Alessia Venturi Editor-in-chief Direttore Responsabile
Digital transformation has been accomplished.
W
e have proof of this every day, when visiting companies for our articles: there is no longer any management that does not choose the Industry 4.0 route. From single coating booths to whole plants, digitisation and automation have found application in all European business models. Industry 4.0 generated 13 billion of investments in one year (2017) In Italy alone1, far beyond the already optimistic forecasts of the Italian government that launched the related investment incentives. The purchase of machinery, hi-tech equipment, robots, artificial intelligence devices, and digital solutions to optimise production has gone hand in hand with the development of clusters of firms that combine their skills to develop applications, software, tutorials, and online training courses offered through special buying platforms, actual digital market places for the manufacturing industry. Once again, the automotive sector has acted as a driving force: long since dominated by robotics in all production phases, it is now turning digital solutions into maintenance assistants, artificial inspectors of coating anomalies, and simulators used to define specific process parameters for each product to be processed. On May 17, during the last Open House of Dürr AG, the world market leader in the production of car coating systems, we have seen the future – above all, the first Automated Guided Vehicles (AVG) for the transport of bodies and materials from one station to another, an innovation stemming from the tendency to design painting plants no longer as a production line but rather as a series of modular workstations. Custom coating application on bodies with no overspray and no need for masks was even more surprising, although it is already going to be outdated by the pro version of this technology, which is currently being tested and will soon offer the possibility of coating logos and lettering in a similar way to digital printing. What you have in your hands is one of the most beautiful and content-rich issues that we have produced in these first ten years of business at EOS Mktg&Communication, the publisher of ipcm®. I would call it a record issue, in terms of both content quality and advertising spaces. There was no better way to celebrate our first attainment than by doing our job (although the actual party is coming soon). We founded our company on the desire to work, on professionalism, on the enthusiasm and the will to offer a completely new product in terms of form, content, multichannel and international distribution, and visibility – not a clone, but something new and fresh able to reflect the world industry’s two main focusses: internationalisation and digitisation. In this issue, including a content-rich special report on coating technologies for the automotive and transport sectors, we tell the innovation stories of several prominent companies from various countries, united by the passion, professionalism, and know-how of those who have contributed to achieving such innovations. We tell about the coating sector. Because communicating is the most beautiful journey. 1 From an article by Luca Orlando, Il Sole 24 Ore, May 14, 2019

This type of machine is used for removal of sand and finishing the surfaces of casted mass products (Fig. 2). Special features bring decisive advantages to the operator. The brackets of the steel mill tumble belt are designed to be particularly wear-resistant. The change intervals extend significantly. The ventilation of the blasting chamber has

this way, the cycle time can be short ened. A longer air outlet is avoided after the blasting process. In addition, the system has comparatively small gaps in the blasting chamber. This prevents jamming of the workpieces and ensures their quality. In addition, the plants will be equipped with the strong and easy-to-maintain AGTOS high-performance turbines. Even the reliable filter technology is a popular advantage due to the maintenance-friendly design. The exhibition team likes to show the details at the exhibit.
Process flow The workpieces are fed to the blasting system by means of a feeding device. A steel caterpillar belt forms a hollow and mixes it. After the machine is closed, the blasting process starts. Highperformance turbines installed in the upper part of the blasting room throw the blasting abrasive onto the parts. This way they are removed from the molding sand and blasted. By changing the belt movement in the forward run the workpieces move back from the blasting chamber into grid boxes, or on a discharge belt. After the blasting process, a coating or the dispatch of the workpieces follows.

of distillers for solvents and cleaning solutions, have chosen to create a partnership precisely in order to keep up with these changes. We have talked about this with Tommaso Ponara, the owner of Water Energy Srl (San Pietro in Casale, Bologna, Italy), and Massimiliano Mingacci, one of the partners of IST-Italia Sistemi Tecnologici SpA (Modena, Italy), during the international event European Coatings Show, where the two companies had a common stand. ipcm®: How did the collaboration between IST and Water Energy start? “It started a few years ago, when IST realised that a sudden transition from solvent-based coatings to more sustainable, water-based solutions was occurring among both users and manufacturers,” says Massimiliano Mingacci. “IST mainly operates in the graphic arts sector and, for some years now, in the industrial coating one, for which it produces cleaning systems for drums and containers dirty with both solvent and water-based paints. We looked for a flexible and close partner, in terms of both location and vision, which could help us offer a complete technology package to our customers. We found it in Water Energy (Fig. 1), a company specialising in the production of process coating water treatment, sludge treatment, osmosis, and chemical-physical systems. “Thanks to this synergy, IST is now able to offer a complete solution for any need: when a firm needs to eliminate paint residues from drums and containers, as well as treating and purifying the waste water produced by this cleaning operation, we integrate our systems with Water Energy’s technology. Recently, the graphics sector also saw an increase in the use of water-based products at the expense of solvent-based ones: this shows that our solutions will be able to also serve new markets in the future.” “This collaboration with IST proved to be a winning choice for Water Energy, too,” states Tommaso Ponara. “For years, we have offered our plant solutions to specific market niches in the coating sector: now, our target also includes the producers and formulators of paints, inks, and pigments, thus expanding our customer base worldwide.” ipcm®: What technological innovations are you presenting at the ECS? “We have just launched two new plants for cleaning bins and drums containing both water-based and solvent-based coatings (Fig. 2).

machine with a gentle rolling movement (Fig. 3).
Figure 3: The troughed belt principle: The work pieces are gently rolling over the transport rods equipped with a polyurethane lining. They do not collide but are passing through the machine by gently touching each other.
The transport rods are covered with a polyurethane lining, which further protects the work pieces from getting damaged or nicked. Since there is a technological trend towards more delicate components, which must be blast cleaned, the gentle work piece transport through the shot blast machine is especially important. The Walther Trowal troughed belt transport system makes sure that the work pieces are passing through the machine without getting damaged. For somewhat larger work pieces with complex shape the troughed belt machine concept also produces better blast cleaning results than spinner hanger shot blast machines: While passing through the trough the work pieces are continuously rotating. This ensures that the blast media is reaching all work piece surface areas, and always from the same distance. The result: All-around highly homogeneous 2 1

You have all the necessary information at a glance for quality audits at any time. A proof of specification is directly visible and comprehensible.
Thermal Barrier The TS04 thermal barriers with heat sink are made of high heat-resistant stainless steel, robust closures and 100% silicone-free insulation material. The microporous insulation and the built-in phase change heat sink provide enormous heat protection in a compact size. Designed for typical cure temperatures of

140 °C - 220° C and cure times of approx. 30 minutes, the thermal barrier TS04-60 measures 60 mm in height, 180 mm in width and 420 mm in length. The barrier provides thermal protection at 200 °C of 0.8 hours.
Thermocouples For temperatures up to 300 °C, probes are available for various mounting methods. This makes sensors with magnets ideal for ferrous workpieces. For other materials, sensors are available with clamps or with open tip, for gluing on (ref. Opening photo). All sensor cables are equipped with double PTFE insulation and additional steel mesh, and are available in various cable lengths. For special applications, other mounting options or materials, such as high temperature glass fiber cable insulation, can be used.
Conclusion Temperature logging in industrial ovens has been applied for many years. The benefit of such procedure is process control and resulting product coating quality. In addition improved oven efficiency and optimized operating costs are possible. All this is directly related to the correct setting of the ovens. The aim of every oven measurement is to bring the energy and the quality of the products into balance so that both are optimized. This is precisely what the PhoenixTM ‘thru-process’ temperature monitoring systems provide.

coating, metalizing or galvanizing (Fig. 3). However, we continuously experienced fluctuations in the blasting results although according to our monitoring, all process parameters, such as blast pressure, distance and angle to the object, were constant.” The cause of the fluctuations was the very quickly during blasting and thereby rapidly lost its grain size. These changes to the blast media were consequently transferred to the blasted surface, resulting in the required roughness no longer being achieved. Even within one production charge of blast media deviations can occur. Jo Tilkin adds, “That is not acceptable if one demands top quality. In addition, the aluminium oxide usage was very high and there were always delivery issues.” In the search for a blast media change, Jo Tilkin came in contact with Bert Gysen from Magistor, the representative of VULKAN INOX blast media in Belgium. Bert introduced Jo to GRITTAL®, an angular and very hard stainless-steel grit blast media, manufactured from high quality raw materials and alloys. Bert saw GRITTAL® as being the solution to Jo’s requirements. That is because GRITTAL® is extremely durable and the breakdown of the individual grains, compared to mineral grit blast media, takes place very slowly.

elcome to the third and final part of our first Five on Five interview. Earlier this year, we asked 15 questions to five senior figures of five leading companies from within the surface treatment industry. We split the answers into three sets of five and with each article we delved deeper into how the industry is embracing Sustainability and facing its challenges, what it represents business-wise and how companies are measuring up to competitors. In case you missed the first two articles you can read them online at www.myipcm.com: - Part I can be found by selecting issue n. 55 of ipcm® (January/February 2019) and scrolling onto page 38; - Part II can be found by selecting issue n. 56 of ipcm® (March/April 2019) and scrolling onto page 28.

Our aim was to give our readers some unique, thought-provoking and hopefully inspiring content to go hand-in-hand with our newly launched sustainable section. The Five on Five format allows for a broad overview of the actual picture of sustainability within the industry, which thankfully shows that each and every player has this as a genuine priority throughout their organisations. Lastly, we would like to thank once again all the below who took time out of their busy schedules to work with ipcm® on this series: the time spent answering our questions alone shows how serious these companies are about sustainability.

SUSTAINABILITY doing this is by developing and marketing products under our Brighter Living Solutions brand – so-called because they are demonstrably better than mainstream solutions in terms of their environmental (e.g. CO2 emissions, resource extraction, waste) and/or social impact (e.g. working conditions and health and safety). Brighter Living Solutions currently account for 62% of DSM’s product portfolio. DSM is striving to be a leader in product stewardship. Our focus is to consume fewer resources overall; replace scarce, toxic or polluting raw materials; extend product lifetimes and enable retrieval and recovery of organic waste streams – all while growing and improving our innovative product portfolio and business performance. Specifically, DSM has identified three key platforms where we can drive sustainable growth: climate change and energy, resources and the circular economy, and nutrition and health.
Can you describe your 11 sustainability program? Joel Svendsen, Belzona – We started working on steel, but of course steel isn’t the only material that suffers from degradation. Over the years we have gone after various different materials, so we can extend their lifespan. In trying to do this, we’ve also strived to not include nasty chemicals or have a high level of toxicity. So, Belzona has tried really hard in using materials that are as environmentally safe as possible. And safe for people as well. These things tend to go hand-in-hand. If you can, use ingredients that have low toxicity or low volatility. Helen Mets, DSM – Our sustainability strategy revolves around people, the planet and profit - and they not only apply to how we view the external world – so the products we develop and the relationships we form across the value chain - but also to how DSM conducts its own operations. We believe that combating climate change is a responsibility and a business opportunity, so we are very active in improving our own carbon footprint and advocating for climate action. We plan to realize 30% of our own carbon footprint reductions. One way the company is
John Falder, HMG – The HMG sustainability program is a way of being at HMG. From your first day you can see how we try to act. HMG Paints is committed to making continuous improvement in the management of its environmental, economic and social impact. We work with our partners to promote environmental care, increase understanding of environmental issues and disseminate good practice.
Fredrik Calenius, TEKNOS – We have defined four focus areas in our CSR program: sustainable solutions & services, responsible operations & supply chain, people development, and future generations. –– Sustainable solutions & services: We invest in and develop solutions and services which are better whether it is for environmental, quality, health, safety or human aspects. This goes beyond just environmental-friendly products; it can be e.g. a service educating our clients. –– Responsible operations and supply chain: We work as a responsible company within our entire value chain, from procurement of raw materials to the manufacturing and delivery of the products to our customers on time, safely and with the respect for the environment. –– People development: We strive to foster a culture based on our company values Creativeness, Persistence and Fairness. People are our biggest asset. We are committed to develop our employees’ competences and skills, attracting the best talents, and creating an environment in which ideas and initiatives flourish. –– Future generations: Continuity describes and affects all our actions. We want to make choices, which bear to all the generations to come. We want to build a company, which the next generation will be proud to lead and be part of in the future.

These promises guide our sustainability initiatives and support the business development from the sustainability point-of-view: –– We drive our portfolio towards maximized performance with minimum environmental impact –– We improve and protect air quality with our products and professional services –– We drive at better resource efficiency with quality, safety and durability on top of our minds

–– We are a responsible and active partner in our communities –– Based on these promises, we are in the process of defining new sustainability targets and agenda.
s there a project that didn’t 12 Iwork out? Joel Svendsen, Belzona – Quite a long time ago, perhaps the 1990s, we put a lot of effort into water-based systems. It was one way of reducing the cost, without incorporating any hazardous solvents into the product. We were able to make these systems work, but we were unable to achieve the same level of performance as the two-coat systems that we already had. So, in the end, the performance
dictated our path. It was the right thing for customers. It was better to have a more expensive solution that lasted longer. From a sustainability standpoint, even if it’s a more expensive solution, if it allows you extend the lifespan and performance of that structure or equipment, it’s worth it. Helen Mets, DSM – Rather than a project per se that didn’t work out, in terms of obstacles, DSM finds itself in a challenging position where it needs to pull the market along. The value of sustainability and sustainable products is not fully understood. Sustainability itself is not the only benefit. Product performance, appropriate price point and even materials that are easier to work with, are high priorities for both industrial customers and consumers alike.
SUSTAINABILITY John Falder, HMG – One of the key areas that we struggled with is plastic. Plastic waste is difficult to deal with, so HMG favours metal packaging wherever possible which can be recycled. As we know there is a worldwide push on plastic usage currently and HMG is fully supportive of this. Fredrik Calenius, TEKNOS – We are still in the very early stages of implementing our sustainability policies so it’s a little bit early to answer this, however so far everything is going smoothly.
UHS platform technologies VOC-compliant coating
Minna Avellan, Tikkurila – Of course, there has been demanding projects during the years – in product development, finding new raw materials, in the development of production processes etc. We have strict quality requirements and if those are not met, we might discontinue a project.
o employees actively participate in these 13 Dprograms or activities? Joel Svendsen, Belzona – I do think it’s important to get our staff involved in these programs and activities as well. I will say, it is much easier these days. In decades past, there was a certain negativity towards environmental initiatives. For example, I remember a lot of people saying “If it’s not a nasty chemical, it’s not going to work well. Give me the really nasty, dangerous stuff - that’s the good stuff!” Crazy to think that people would have had this approach to sustainability. So, certainly it’s good to see people move away from this standpoint. Helen Mets, DSM – Sustainability is part of our DNA and we have a shared mission and regard ourselves as a “purpose to life” company, so our employees are actively engaged in all aspects of our sustainability activities – from energy saving initiatives to research & development. Our extensive scientific community – or who we refer to as our Bright Science team - are dedicated to creating innovative, sustainable solutions in the fields of nutrition and health, climate and energy, and resources and the circular economy. John Falder, HMG – Yes, employees from all levels of the business actively engage in programs and activities. Especially those activities which have an impact on our
UHS-Systems The conversion from solvent-based to water-borne coating systems is often linked with high investment costs. The new ultra-high-solid platform technologies from FreiLacke can significantly reduce solvent consumption, even without system conversions. FreiLacke is now using its new ultra-high-solid systems (or UHS for short) which entirely meet the demands for a reduction in the VOC content in paints and coatings. With a solids content of up to 80 percent by weight, they have a VOC value of less than 350 g/l. www.freilacke.com

local community and those that have an impact on the day-to-day running of HMG. This has been reflected in the two BCF Coatings Care Awards that HMG has won. Fundamentally, it’s also key that employees are sustainable away from HMG, being good neighbours and providing a positive impact on society. Fredrik Calenius, TEKNOS – During 2018 and late 2017 Teknos conducted internal stakeholder interviews and workshops to define key priority areas and materiality for its sustainability work. The process started with an initial stakeholder interview, which was held in autumn 2017 by a third-party organization and was followed up by the establishment of a CSR team and ongoing workshops and interviews with key stakeholders inside the organization. Stockr @ shut terstock

N. 57 - MAY/JUNE 2019 - international PAINT&COATING magazine
The CSR team represents different functions and units of Teknos including R&D, QEHS, Procurement, Sales, Marketing, Product safety and HR to ensure that the voices of internal and external stakeholders are taken into account. In spring 2018, Teknos involved over 130 people in face-to-face workshops from different business functions and countries across the organization to define the most crucial topics, opportunities and risks in terms of sustainability. The future will show, but we surely hope and anticipate that our employees will continue to participate actively. Minna Avellan, Tikkurila – Depending on the country, employees can participate in various sustainability-related campaigns and projects, for instance community involvement projects and safety campaigns. Moreover, we
have been inviting people to contribute in the development of the company’s sustainability agenda. This is an important topic and we will definitely put more efforts to engaging employees.
hat is the role of third-party 14 Wcertifications in sustainability
within the paints and coatings industry?
Joel Svendsen, Belzona – Their biggest role is in the realm of energy efficiency. Most importantly, they’re helpful because there is a temptation to make poor decisions when they aren’t in place. They ensure people look at the long-term goals and aims, rather than short-term, easy-to-achieve “success”.
SUSTAINABILITY Helen Mets, DSM – Third-party certifications play a very important role for their ability to instil confidence and trust in consumers. They raise the bar in consumer choice – so much so, that they function like a demand driver, particularly for more sustainable, safer and high performing products. John Falder, HMG – The BCF Coatings Care program has been important. Even though Coatings Care is a voluntary programme, it’s a great basis for good management practices. It offers HMG and other participating companies the opportunity to pursue a common, effective management approach for their health, safety and environmental programmes and advises best practices on how to achieve high standards by self-assessment and by measurement of improved performance.
Fredrik Calenius, TEKNOS – Sometimes it can be hard for customers to understand or even believe a company’s sustainability claims. Third-party certifications are a good way to demonstrate to different stakeholder that the company lives up to its sustainability claims and also to help customers to choose the most sustainable option, i.e. to increase trust in the company and to help customers make the right choices. In my opinion, the coating industry makes no exception in this. As the interest and knowledge from the customer’s side for these certifications grows, they can also prove to be a competitive advantage, and help the whole industry to develop towards a more sustainable direction. Thus, I believe that certifications have a big and increasing role for both customers and coating companies.
Minna Avellan, Tikkurila – The third-party verifications reflect proven and standardized quality, durability and safety of our operations and products. Because we want to continuously improve our performance and promote the sustainability aspects of our operations, different kind of third-party certifications are a trustworthy proof that we are progressing and meeting the international standards. The majority of Tikkurila’s sites are certified according to the ISO 9001 quality management system standard, the ISO 14001 environmental management system standard, or the OHSAS 18001 health and safety management system standard. The certificates confirm the compliance of our management, processes and practices with the international quality, environmental, occupational health and safety standards,

and ensure that those are developed systematically. Within our portfolio, we have more than 300 eco-labelled products. The ecolabels include the Nordic Swan Ecolabel, EU Ecolabel, M1 classification measuring low emissions and allergy label.
ow do you see the future of 15 Hsustainability? Joel Svendsen, Belzona – I think something we have to accept about the near-future of sustainability is that for some areas, there are no alternatives to petroleum products. For operating airplanes and ships, vessels that need to carry a great deal of energy, we’ll see petroleum for a long time. However, as battery technology improves, we’re going to see more and more things moving away from petroleum power. Cars are leading this shift. I think we’re going to be increasingly shifting to electric cars, which means our power plants must be bigger. Previously, it was thought the size of power plants, or our electrical distribution networks didn’t need to increase. People thought that we could continue to improve energy efficiency in lieu of our energy infrastructure. But it’s much more efficient to produce power in a plant, rather than in an electric car. And of course, by using electric power you open a whole load of other energy sources such as wind power, geothermal etc. – areas, which we are already working in and providing repair and protection solutions. We predict that there will be more work for us in electrical

distribution, battery manufacturing and mining materials for the batteries. Helen Mets, DSM – Becoming more circular and reducing carbon footprint are the most pressing challenges for industry to solve. We have to think big and bold and develop a future where every product has a value proposition which supports its sustainability credentials traceably through the supply chain, as well as performance - and at an affordable cost. DSM believes there will be opportunities created by dynamic shifts driven by positive changes in consumer behaviour and rapidly emerging
technologies. We will become even more focused, extending our innovative spirit into new industries and applications, challenging boundaries and exceeding expectations about what sustainability can deliver. We will also continue to lead the charge through advocacy to truly shape a sustainable future. John Falder, HMG – The next steps for HMG are keeping sustainability on our agenda with continuous improvement
across the business and extending this to our upstream and downstream partners. Sustainability has played an important role in the previous 88 years of HMG Paints and we believe it will play an equally important role in the next 88 years. Fredrik Calenius, TEKNOS – Sustainability will be more and more important in a company’s success. In the future we believe that the focus will be on developing new business models and solving the social and environmental problems. This is the way we will build our business. Elisa Markula, Tikkurila – Our purpose is to offer “surfaces that make a difference” and that includes sustainability as a part of our DNA. Especially Millennials want to work in companies that have a purpose and when we embed sustainability as part of our core, we believe that we will not only attract new talents but also engage our current employees to serve our purpose. We will continue the work in all operations and © Belzona functions in our company as everybody has a clear role to execute sustainable actions in their work, and we want to make that work more visible through clear measurements and KPI’s. We will require more sustainable actions also from our suppliers to keep developing truly sustainable products and services and increase our communication towards stakeholders, especially for our customers. We want to be seen as the most responsible and sustainable employer and player in our market areas.

While coating thicknesses with the old coating system line generally varied between 150 and 200 µ, the use of the new system was able to lower the coating thickness by approx. 80 µ down to 120 µ. A high level of process control, due to Nordson’s Dense-Phase Technology, will allow the customer to achieve further powder savings and higher quality as he can precisely control his powder application in further optimizations.

The piece-carrying skid then reaches a lifting platform, which transfers it to the bridge crane that handles the flying bars along the pre-treatment and cataphoresis tanks. All other products, including the ones that the company coats as a contractor, are hung onto the FUTURA power&free overhead equipped with different storage buffers; this is done by means of an elevator with a 5,000 kg capacity located in the loading station (Fig. 7). “The parts are hung to the flying bars and then to the FUTURA load bars, which directly proceed towards the pre-treatment and cataphoresis line without going through the tilter or the lifting platform,” explains GEINSA

Moreover, the line employs a reverse-cascade system and draining units, exploiting the water with a lower conductivity value to reduce that of the tanks with lower quality,” explains Jon Franco. Thanks to a telemetry system and continuous data collection by its software package, the whole plant is monitored and controlled from one management room (Fig. 11) located next to the pre-treatment and cataphoresis line.

In the first step, osmosis lowers such value to 60-70 µS; the second brings it under 10 µS. The system can generate 12,000 l/h of water with conductivity <60 µS and 7,000 l/h of water with

operators can control the entire plant from a single location, without having to monitor each PLC. During loading, a 24-digit barcode is associated with each workpiece; besides transferring all process information to the different stations of the coating system so that they work according to the matching program, this also collects all the process and treatment parameters required for traceability.” In the tank #8, i.e. the cataphoresis one (Fig. 12), the flying bars are separated from the bridge crane to ensure that the voltage is not transmitted to the factory structure and they are swung to eliminate the air bubbles generated during immersion. Only in this way can the deposition of the cataphoresis coating be uniform on the entire workpiece surface. The cataphoresis tank was designed to treat a maximum surface area of 150 m2, although the average surface of

iron and aluminium, and therefore we chose to use a multi-metal pre-treatment technology with Chemetall’s Oxsilan product. This is a great advantage with a view to the future development of our contracting service. Indeed, our main raw materials are carbon steel and galvanised steel (also from coils), but flexibility is the real strength of this new coating plant.

a chassis ranges between 70 and 75 m2. “The thickness to be applied is very high: it ranges between 40 and 50 microns, i.e. greater than the thicknesses normally applied to car bodies,” says Jon Franco Labrador, “because the impact of gravel on semi-trailers is much more severe than on a car. The tank is therefore equipped with a 1,200 amp rectifier to evenly apply such thicknesses over a surface up to 150 m2. Lecitrailer, e.g. semi-trailer tippers, reach this size.

These have also improved in terms of aesthetics: unlike the silvery tone of galvanised steel, the grey cataphoresis layer enables us to customise all products with the RAL colour required by each order – which is going to last over time, as we give a 10-year anti-perforation warranty. Finally, although we conventionally apply a two-layer system including cataphoresis + polyurethane finish, we can guarantee even greater protection upon request with a three-layer coating that includes cataphoresis + epoxy or zinc-rich base coat + polyurethane finish.” “We have favoured flexibility over productivity, even though the coating capacity of this plant is much higher than our needs: the production takt time is 28-30 minutes, whereas the coating one is 15 minutes, i.e. about double,” says Martín. “Our objective is to increase the coating quality of Lecitrailer’s whole production, by offering better performances to our customers, while at the same time starting to offer a contracting service ourselves.

an RFID tag that uniquely identifies it. During coding, we match the FPT identification tag (containing all product data, such as GAN, serial number, design, client, date and time of progress, and FPT approval state) with the related coating program. From that moment, the match between the bar number and the carried workpiece is unique,” explains Renato Piazzolla. “Thanks to the MES software system, a first quality gate enables us to detect eventual anomalies: after a gun reads the barcode,

the MES displays a check-list on a dedicated monitor, based on which the operator can identify any native defect of the workpiece. We can thus immediately identify right, at the beginning of the production process, any non-conformities such that the workpiece does not have the necessary requirements for a correct application of paint (blocking non-conformity). “The component database is shared by Pieffeci and FPT and it is continuously updated. We carry out a weekly update of our coating programs matched with FPT designs,” states Mario Rizzolio. “Currently, we have 70 coating programs to handle 12 macro-families composed of the about 4000 products that make up FPT’s production range and that can even only differ in the position of a sensor. Our team constantly updates the database following the addition of new product variants and matches them with the part-specific coating programs; or, if needed, a new program is defined.” The plant’s takt time from coding to unloading is 56 seconds. Pre-treatment (Fig. 2) occurs on an Imel plant with Henkel products. The cycle includes six stages: alkaline degreasing, rinsing with mains water, rinsing with demineralised water, phospho-degreasing with light iron salts, rinsing with demineralised water, and further rinsing with demineralised water. The next stage is a blow-off operation performed in a fixed station at the end of the pre-treatment tunnel and in two robotised stations (Fig. 3), one on each side, which act on specific deposit spots following pre-set programs. “Before this 4.0-oriented investment, we generated a single FIFO queue of coating programs during the coding phase,” says Renato Piazzolla. “Now, after our RFID readers read the tags placed on the load bars, the various machines of the line, such as for example the blow-off robots, collect the data related to each program

Each workstation has a different FIFO queue. The plant is composed of seven different chains – slow, very slow, and fast. With the old management system, a FIFO queue was created during coding and the parts were transferred from one chain to another with the risk of not following the FIFO order and thus generating gaps. The current management system, on the other hand, detects any gaps on the chain; moreover, the creation of a FIFO queue for each workstation has eliminated a problem that made the company lose valuable production time.” decides to make a last-minute program change for any reason, there are no consequences on the overall coating cycle.” Subsequently, the parts enter the drying oven at 60 °C for 30 minutes to eliminate any residual moisture or water deposited in blind holes (Fig. 4). At the exit of the oven, there is a cooling station where an AHU lowers the temperature of the workpiece to make it immediately processable. This is followed by a masking phase with bags and thermoformed films that protect the hubs and studs of axle bridges. Whenever the RFID reader detects a tag, the MES projects part-related work instructions on the Smart TV in real time, until the next reading (Fig. 5); this applies to both masking and sealing instructions. “In this area, we manually seal specific areas of the rear axles intended for Stralis trucks, in order to prevent oxidation on some boxed surfaces (Fig. 6),” explains Mario Rizzolio. “After coating, on the other hand, we automatically perform conventional sealing operations on all the areas of the light axle range requiring it.” At this point, the bridges reach the actual coating area.

Ideal for OEM, repairers and builders within a demanding marketplace, Acrythane 4G has an optimised balance of early hardness, fast cure and long pot life. Its ultra-fast air-dry properties create process and energy savings for users. Developed to provide outstanding gloss, final appearance and properties over traditional systems. “I have been using HMG products for many years now, the 4G product is without doubt the best gloss I have seen from a Commercial Transport coating” said Kenny Wells of

Figure 2: Utilising HMG’s innovative UNIT LITE tinting system Acrythane 4G is available in a wide variety of colours including RAL, BS and Commercial Vehicle standards.
With its revolutionary “one visit application,” Acrythane 4G does not require the end-user to observe the usual intermediate flash-off time. This allows the end-user to save not only time but also energy and materials. Feedback from early users included comments such as “4G is a fantastic product! From its application to its flow out, resulting in an outstanding gloss finish. We just love it.” Brendan Whelan, Enniscorthy Autobody Ltd. Johnie Lee of South Derry Commercial Spraying commented “I am very happy with HMG’s 4G top coat, the thinner options allow me to control the speed in colder and warming weather. This is very important to me as one person painting a large area needs full control of the speed of application.” Acrythane 4G is both VOC and REACH compliant and available as both a coloured top coat and clear coat. Utilising HMG’s innovative UNIT LITE tinting system Acrythane 4G is available in a wide variety of colours including RAL, BS and Commercial Vehicle standards (Fig. 2). 4G can be applied by conventional gravity and HVLP spray guns, giving coverage of 9.3 square metres per litre until 50 microns film thickness. Surface preparation is as simple as a solvent wipe or shot blasting.

of technical and sales employees. Both its one and two-component systems achieve excellent anti-corrosion, mechanical, and chemical performance levels. As for application, they are much appreciated for their ease of use and resistance. Very long pot life, high verticality, and excellent distension are the main features of new generation water-soluble paints (Fig. 3). Among water-based products, Direct-to-Metal (DTM) or “one-coat” products represent a niche of ever-growing importance; these coatings, in fact, enable to replace primers and top coats with a single coat of paint. Franchi&Kim offers both one-component alkyd or polyurethane and two-component acrylic solutions. The latter, in particular, are the core of a new coating philosophy that combines high performance with great ease of use. Indeed, twocomponent acrylic DTM products simplify coating by allowing to use only one paint and one catalyst instead of a traditional epoxy primer and a polyurethane finish with their respective catalysts. This is a considerable advantage in automatic systems with limited tanks for painting products: by simplifying the coating cycle, it is possible to allocate more space for a higher number of colours. Using only one coating brings benefits also in terms of equipment cleaning, since epoxy, polyurethane, and acrylic products have different requirements for pipe cleaning solvents. This reduction in materials and products also eliminates many problems and errors that may arise when different catalysis percentages must be adopted if different catalysts are used, which can generate confusion and mix-ups among products; the reorganisation and stocking operations are also considerably

easier to manage.
The use of a single product speeds up the paint application phases. In many cases, by taking advantage of the verticality of the Franchi&Kim formulations, it is possible to obtain the required thicknesses (70 to 100 µm) with just one coat or to apply two coats with a wet-on-wet process, without any downtime for repainting. This also applies to any oven process, which does not require a first stage for the primer and a second one for the top coat.”

Franchi&Kim’s new DTM coatings have very long pot life times of up to 90-120 minutes, thus enabling to set the cleaning process and any system alarms with very high parameters and ensuring excellent continuity of use, without the waste due to unnecessary plant cleaning operations. The use of a single product speeds up the paint application phases (Fig. 4). In many cases, by taking advantage of the verticality of the Franchi&Kim formulations, it is possible to obtain the required thicknesses (70 to 100 µm) with just one coat or to apply two coats with a wet-on-wet process, without any downtime for repainting. This also applies to any oven process, which does not require a first stage for the primer and a second one for the top coat. Franchi&Kim’s two-component acrylic DTM products have a high cross-linking reactivity and they are fully hardened with a quick dwell time of 40 minutes at 55-60 °C. Once out of the oven, the workpieces can be packaged and stored immediately.

This mixture is then separated in the subsequent lamellar decanter. Such separation leads to the formation of two flows: water, free of any dissolved substances, and sludge, collecting all the removed impurities. After filtration with sand and coal, water can be discharged; the sludge collected from the bottom of the decanter is sent to a thickening and dehydration section with a plate filter press.

n the field of surface treatments, the automotive industry is certainly among the sectors demanding the highest coating performance and compliance
with the most stringent requirements. One of the most overlooked aspects in this framework is the paint stripping of car components that need to be recovered and reworked. The number of these parts is higher than one might think and the complexity of this operation is determined by the different materials used (aluminium, zamak, galvanised sheet metal, steel, etc.) and the number of recovery attempts made on defective parts, which are uneconomical to eliminate from the coaters’ production process (ref. Opening photo). PSP Sverniciature Sas (Bornasco, Pavia, Italy) specialises in the maintenance of frames, hooks, and piecehanging accessories intended for coating lines and in the recovery of coated parts that present any defects. During its history, it has implemented all development stages of the various stripping technologies. “PSP was among the first companies to start a paint stripping contracting business at the end of the 1980s,” says Massimiliano Prederi, the owner of this firm together with his wife Elena. “The development of this field contributed to regulate both the paint stripping of coating hooks and the recovery of defective parts, which used to be performed with operations that did not respect health and the environment. “PSP started by using the cryogenic technology to paint strip frames and hooks. Then, we implemented the thermal technology with a pyrolytic oven for the Opening photo: Car components such as windscreen wipers and roof rails are among the most complex products to paint strip.

FASTRIP’s requirements “The FASTRIP paint stripping plant installed in the factory of PSP is a modular system with one tank,” says Alit Technologies owner Loris Rossi (Fig. 2). “The parts are loaded into a basket that subsequently enters the first tank, where they are treated at a temperature of 120 °C (Fig. 3). During the spraying of the paint stripping product, the basket rotates by 360° for the whole cycle, which ends with a suction phase. After checking that all workpieces have been properly stripped, the basket is removed from the stripping tank and is placed in a second, identical tank containing water at 70 °C to rinse the components. In this way, after verifying that they have been stripped in compliance

structure allows replacing only the saturated bath while using the second tank for cleaning and rinsing, so that it is not necessary to completely replace the stripping solution. However, Alit did not only design and supply a mere paint stripping plant. “Besides meeting the customer’s paint stripping requirements,” adds Rossi, “our staff identified other critical issues related to this process. That is why we tried to provide PSP with a complete system integrated with all useful devices to make its operation cost effective and eco-friendly. In addition to the new stripping technology, our engineers designed and installed a diathermic oil heater, a scrubber for fume abatement, and a sludge treatment unit.”
PSP chose to add this new treatment to the ones already performed with the aim of offering, in addition to the paint stripping of coating frames and accessories, a process suitable for all the materials that are difficult to handle with the cryogenic and thermal technologies, such as for example the aluminium workpieces constituting automotive components and design products like handles and lamps.”
paint stripper and the waste produced by the coating removal process, are gathered in a decanter to be dehydrated and then filtered with a filter-press specifically developed to recover the paint stripper, which is separated from sludge and recirculated into the machine with some fresh product. The solid residue is disposed of as special waste.
The advantages of the new spray technology “Thanks to the technology installed,” says Prederi, “for our chemical paint stripping process we can use products with a low environmental impact, which are activated at 120 °C (i.e. almost the double of the temperature required by immersion processes, occurring at 50 or 60 °C) but

longitudinal direction in the simulative model construction until it buckles. The U-profile buckled at a force of 49.2 kN. The OEMs’ specifications – depending on the vehicle model – are only approx. 35 kN. The over-sizing was already evident here. For this reason, the second step was to investigate up to what plate thickness the U-profile can be reduced under a given buckling load of at least 35 kN without neglecting the required buckling strength. The simulation showed that the sheet thickness of the U-profile could be reduced to approx. 2 mm – with full compliance with the required buckling strength. This means that the mass can be minimised by up to 30%.
The daily work and development of long-lasting corrosion protection technologies drove Dörken MKS to the question of how high the theoretical weight reduction of components can be through wall thickness reduction.

Zinc flake coating: Low wall thicknesses with the same component performance The results were clear: The 2 mm wall thickness test specimen coated with the zinc flake system performed without red rust infestation in all three corrosion tests. 1,000 hours in the salt spray test and six cycles each in the climate change tests were achieved. At the same time – both loaded and unloaded – a bending stiffness between 3.2 and 3.4 kN/mm was achieved in the 3-point bending test. By way of comparison: The 2.6 mm thick U-profile showed recognisable red rust infestation at the same times and an unloaded bending stiffness of approx. 4 kN/mm and values between 3.8 and 3.9 kN/mm after loading.
Within the scope of the study, the influence of corrosion on the mechanical properties was also investigated with the aid of a 3-point bending test (based on DIN EN ISO 14125). The bending test showed hardly any deviations between the test specimen with safety pad and the 2 mm thick U-profile. If it were not for the risk of corrosion.”
Weight saving due to effective coating system The ACS study commissioned by Dörken MKS shows: The additional 0.6 mm, which is planned in practice as a safety component, can be saved with the aid of effective corrosion protection. It became clear that this could also reduce the buckling strength. An effective corrosion protection thus fulfils both the different corrosion properties and the mechanical properties and can lead to an overall saving of around 30%. More than promising for the future of lightweight construction!

For over thirty years Novaresine has been creating highly innovative products to meet the needs of the alkyd and polyester resin market. Continuous investments in research and technology allow us to offer a cutting-edge brand for various sectors, with a wide range of products to cover the specific needs of the clientele.
“As for the coatings, the Salcomix system enables us to create custom-made products. We supply Officine Pilla with three types of white and a grey shade, mainly used for counter-frames,” says Picciotti. “However, we have also happened to be required particular types of orange or green, which we have custom-produced for Officine Pilla. This is the advantage of the Salcomix system: it allows us to create tailor-made products based on customer requests while ensuring excellent quality performance and result repeatability.” The latest innovation implemented by Officine Pilla in terms of coating was the adoption of electrostatic guns. “Whereas for coating small parts we use Graco airmix guns and pumps (Fig. 5), at the beginning of the year we also implemented Graco Pro Xp electrostatic guns with Triton pumps (Figs. 6 and 7) to paint large workpieces,” explains Nicola Pilla. “This project was also developed in collaboration with Colormax, which supplied us with the whole equipment. The electrostatic system has enabled us to increase our application speed and improve coverage. Moreover, although it has been adopted for a relatively short time, we have already observed a 30% product saving.”
All-round collaboration “Colormax has been our only supplier for our entire coating process for many years now,” says Nicola Pilla. “The relationship that has been created now goes beyond a mere working relation.

environment. One aspect is detailed hygiene regulations. For example, employees must change their gloves and clean the workplace before starting production. There are also measures to prevent contamination or dust, as well as glass and blade management procedures. Maintenance regulations and checks on the machines, systematic pest control throughout the entire factory premises, requirements for the controlled use of all working materials, especially greases and lubricants, and a secure goods receipt complete the package.
Seamless traceability Schütz manufactures the Cleancert packaging just-in-time on the basis of specific customer orders: the IBC inner bottles are transferred to the final assembly stage and installed immediately after the blowing process. Each production step and each component can be clearly assigned to the corresponding packaging. Identification via a barcode system enables complete traceability, right down to the batch and process level. On request, Schütz can also assign individual identification numbers for articles or packaging materials. Finished Cleancert IBCs are loaded indoors and shipped directly without intermediate storage. Pre-produced components such as screw caps, outlet valves or bung plugs are also hygienically packed in small quantities and stored separately. If dispatch is to take place at a later date, the containers are stored in special closed rooms. Optional plastic covers offer additional protection. Combined, all of these precautions make a considerable contribution to maintaining the quality of the subsequent filling product.

ema brings high performance to manual powder coating: The PowerBoost function of the new OptiFlex Pro series delivers 110 kV high voltage
and 110 µA charging current at the touch of a button. With this full increase in power, any coating, even with the most difficult powders, can be applied quickly and safely. Coating large areas manually takes time and effort. This fatigues the coaters and lowers the coating quality. Gema’s solution to this problem is PowerBoost. Directly at the new OptiSelect Pro manual gun, 110 kV high voltage and 110 microampere additional charging energy can be activated via a button (ref. Opening photo). The result is maximum area performance and greatly improved productivity, even with the most difficult powders. The maximum charging power of 110 kV over the entire working range optimally charges the powder particles in every situation and regardless of the type of powder. Gema has made no compromises on safety. The OptiSelect Pro manual gun was designed, tested and certified by Gema as usual for maximum operational safety. This also applies to all accessories of the new line.
PowerBoost - the interaction of the latest technologies PowerBoost is the integrated interaction of coating gun, control and flat spray nozzle. The components newly developed by Gema and designed for PowerBoost result in a high total area performance with clever fan expansion of the powder cloud. This works like a broad brushstroke and enables fast work with perfect layer build-up. The high coating performance, the precise control with the proven DVC and PCC functions and the

Cost is always an important factor for any coating but it’s even more sensitive for decorative paints.
154
N. 57 - MAY/JUNE 2019 - international PAINT&COATING magazine
SUSTAINABILITY can only be achieved by resin manufacturers, integrated coating companies and other additive suppliers working together. Collaboration is not always an easy process but it is much more likely to achieve real change.
Overcoming barriers to adoption Cost is always an important factor for any coating but itâ&#x20AC;&#x2122;s even more sensitive for decorative paints. Fluctuations in the price of raw materials have a key role to play here and one in particular, cobalt is currently undergoing a significant shift. The relative price between cobalt and cobalt free driers has always been significant however, shifts in the cobalt market are closing that gap. As cobalt is increasingly required to produce lithium-ion batteries for mobile phones and electric vehicles, the availability of the metal is decreasing. This is driving up prices and the coatings industry, as a relatively minor user, will bear the brunt. As such, the increasing cost of cobalt could act as a potential driver for the faster adoption of sustainable alternatives. The challenge for the alkyd resin market is to produce a solution that offers the same performance attributes with lower VOC levels at the same, or lower, price with proven sustainability credentials.
Sustainable without compromising performance While bio-based product penetration has progressed well in many industries such as cosmetics and detergents, in the paint industry, green chemistry has so far remained below 5 to 10%. This low adoption rate can be explained by two key factors; technical performance and cost. From a technical perspective many coatings based on water-based alkyds have struggled to achieve the required performance attributes such as gloss, adhesion and resistance to corrosion. There is also a need for further development of bio-based di-acids as those currently available on the market have a number of performance limitations. An alkyd could be up to 100% bio-based and performing. The basic components that make up an alkyd are fatty acids, di-acids and the polyol. All three can potentially be extracted from natural non-fossil resources. An example is the polyol Voxtarâ&#x201E;˘ M100 provided by Perstorp AB, that is 100% Bio-based and produced with a heavily reduced carbon footprint.

oating, adhesive bonding, sealing, painting – these are just some manufacturing operations calling for profoundly clean, and sometimes activated, part
surfaces. It is with these requirements in mind that Ecoclean has developed a set of new cleaning solutions. One of them combines wet chemical and low-pressure plasma cleaning in a single machine. Another innovation consists in integrating diverse applications for partial or full-surface cleaning or activation – e.g., atmospheric pressure plasma treatment, laser, CO2 snow blasting and/or surface inspection operations – into
one processing system. This toolkit enables operators to cover virtually all pre-treatment needs. In automotive manufacturing and its supplier industries, mechanical engineering, aerospace applications, precision and micro-mechanics, medical and optical systems, electronics and other fields of industry, component parts are subjected to cleaning in order to prevent quality problems in downstream processes and to ensure flawless product performance.

Ultra-fine degreasing by a combination cleaning process with integrated low-pressure plasma treatment For workpieces made of steel, aluminium, glass, ceramics and some other materials that are cleaned in batch processes – whether in bulk or arranged in part carriers – the company has developed a combination cleaning technique merging wet chemical cleaning with a subsequent plasma cleaning step (ref. Opening photo). To this end, a low-pressure plasma cleaning operation is integrated into the wet chemical cleaning line. Since virtually all components needed for this cleaning technology – e.g., vacuum, measuring and control equipment – are already in place in the manufacturer’s wet chemical cleaning machines, the additional cost and engineering

and industrial cleaning water. The technology developed by this company naturally increases the efficiency of processes through a resource with a very low cost and environmental impact, which often results in the minimisation or even elimination of chemical additives and in the reduction of energy costs. Finally, Biokavitus’ systems are characterised by a low investment cost, which is also reflected in their management costs. Indeed, these machines take advantage of the formation of nano bubbles, air, and different gases within the fluid to be treated; their technology can be applied to all industrial sectors, such as automotive, mechanical engineering, aluminium die-casting, precious metal processing, textile, food, and many more. The flagship product of Biokavitus’ range is the Phoenix equipment (Fig. 1), intended for the regeneration of industrial liquids and already adopted as an innovative technology by some of the leading European automotive companies. When used to regenerate cooling lubricant emulsions, Phoenix guarantees the effective separation of pollutants, such as oils and metal particles, from fluids. The nano bubbles generated by this system act as a natural “filter”, which captures and brings to the surface all extraneous oil, thus allowing a subsequent removal not only of the decanted particles, but also of the suspended ones. Similarly, it guarantees the effective separation of extraneous oil linked to metal particles produced during machining, which can thus be removed through filters designed specifically for this application. The formation of nano bubbles of air into the process fluid leads to its over-saturation, very different from conventional oxygenation occurring through standard technologies. The nanometric dimensions of the air bubbles multiply exponentially the benefits obtainable, such as for instance the effective control of odours correlated to bacterial charge. Moreover, Biokavitus’ technology ensures better cleaning of machine tools, thus reducing the plants’ cycle time and improving the skimmers’ performance. This improves the entire production cycle through greater economic savings, performance level, and environmental protection. Besides being used for treating cooling lubricant emulsions, Biokavitus technology allows performing effective and accurate cleaning processes, even at low temperatures. The washing water is cleaner thanks to the induced flotation of suspended particles and extraneous oils, which results in a clean and odourless process. When used to regenerate industrial cleaning water, the Phoenix device guarantees better purifying action on difficult-to-clean parts and better skimmer performance, but it also reduces the use of detergents, water consumption, waste water disposal costs, and energy costs for heating the cleaning water itself.

Processing Component Surfaces – a Multifaceted Task
© Rösler
ICT - TECHNOLOGY OVERVIEW
Although the surface quality of the component depends on the utilised printing technology, design and material, post-processing is nevertheless indispensable in most cases. This involves a great variety of tasks. They range from removing the build plates, support structures and residual powder, as well as processing the usually rough surface – for example by means of smoothing, polishing and rounding – right on up to cleaning the workpieces in order to assure the required cleanliness for downstream processes (e.g. coating, bonding or welding). These manufacturing steps are still frequently executed manually which is costly and time-consuming, and leads to inadequate reproducibility of the final result.
Reproducible and Efficient Post-Processing The first step required for processes based on powder beds is to separate the workpieces from the build plate after coarse removal of the powder, for which vibration systems with targeted oscillation

parts2clean 2019: Future-proofing the Cleaning of Industrial Parts © Deutsche Messe AG
I
n light of global trends such as electromobility, autonomous vehicles, lightweight construction,
miniaturization, automation and digitization, the industrial parts and surface cleaning sector is facing new challenges. parts2clean 2019 shows how these challenges can be met. The 17th International Trade Fair for Industrial Parts and Surface Cleaning will be held from 22nd to 24th October 2019 at the Stuttgart Exhibition Center. Areas of current interest include new and modified production technologies, such as the growing use of adhesive bonding, laser welding and coating processes, as well as the additive manufacturing of components. At the same time, there is increased demand for the cleaning of workpieces made from new materials or material combinations,

cleaning with compressed air. The Guided Tours will be offered in English on all three days of the show. Focusing on selected exhibitor stands, they give visitors the opportunity to gather information about specific areas of interest in industrial parts and surface cleaning at every stage of the process chain. For them it is a quick and easy way to discover relevant solutions and innovations and identify likely suppliers who can solve their problems. The Guided Tours are also an excellent business opportunity for participating exhibitors, who can present their products and innovations directly to a pre-selected target audience at their stands, resulting in additional contacts and sales prospects.
