inding the extraordinary in the ordinary. Sometimes, this means to invent. To tune to a more subtle wave frequency in order to innovate where it seems that everything has already been invented. And to be able to see new potentialities in the common reality. For example, the sun can be exploited as a cooling source thanks to the invention of a new two-layer coating system that filters a part of the sun’s rays and converts heat into light, cooling below room temperature. It is as if the paint turned into a thin layer of ice that becomes thicker and thicker as the sun gets stronger. This is the topic of one of the articles that inaugurates the new editorial year of ipcm®. The January issue of a magazine reflects what is coming next, the mood of the market after the Christmas break, and even the laziness of the first weeks of a the new year, when there are twelve months of discoveries before us and it seems impossible to plan them all. Starting the new year with an issue full of brilliant articles is the best way to take stock of the year just ended. When the ipcm® project was born, one of our main goals was to offer knowledge and experience with a new perspective to our partners and readers all over the world. Nine years later, thanks to a long but constant growth that brought us to every corner of the world to show the highest achievements of the coating and surface treatment industry, we are pleased to say that we have made it. In this issue, we will continue to deal with both conventional and nanotechnology pre-treatment processes and their key role in surface treatment cycles in order to ensure quality, presenting two case studies about companies that have focussed precisely on pre-treatment to achieve success with their products. Again focussing on quality, we will also deal with corrosion protection: super durable coatings, new raw materials for anti-corrosion paints based on zinc powder, fluoropolymer coatings for high-value infrastructure. Finally, we will present the successful case of an Italian company, a world leader in the integrated water resources management field that maximised the energy, production and environmental efficiency of its finishing processes thanks to the design skills and expertise of a coating plant engineering firm and to a high automation level reached following 4.0 principles.

available as part of complete coating systems from the WAGNER Group. Special flushing devices allow for consistently sharp, or if required point-accurate markings of the type that are important in adhesive processing, including with quick-drying inks. The robust and high-quality construction, on the other hand, safeguards smooth production processes in even the most difficult conditions. To allow the processing of abrasive or moisture-hardening materials as well as quick-drying inks, Walther Pilot has a variation of this product in its portfolio: the robust, fully automatic PILOT GA 9010 Marking Membrane has a membrane instead of a needle seal.
One signwriting gun for many applications While Walther Pilot has so far offered three spray guns and a complete system for line and spot marking, one gun now reliably covers the entire broad bandwidth of possible applications. Markings on cog wheels, for example, help make assembly errorfree. In steel production, thanks to the use of signwriting guns working in parallel, batch numbers can be written onto steel coils that are still decipherable even from a great height. In sawmills, on the other hand, the absorbent surface of tree trunks is marked for

The spray gun is also ideal for applications such as machinereadable line markings on pipes and profiles, or the colour marking of currency notes that are to be destroyed.
Special signwriting inks prevent blockages of the nozzle During spot and line marking with the GA 9010 Marking spray gun, signing inks are used which are ground to a high quality meaning these inks are less prone to blocking the nozzle than conventional coating materials. The inks are marketed by Walther Pilot and are available in all popular colours. Special colours are available on request. The signwriting inks can be used on wet, hot (up to 800°C), smooth, porous or even greasy surfaces. This means that they are perfect for marking on panels, pipes, plastics, textiles, glass not to mention also wood, paper, ceramic or rubber. They are quick-drying, provide good coverage, oil-resistant, light-fast and waterproof.

Walther Trowal: New Modular Controls Enhance the Process Safety of Mass Finishing Applications especially when different work pieces must be treated (Fig. 1). At the Euroguss exhibition Walther Trowal presented a mass finishing system for finishing of castings equipped with a brand-new control panel.b This allows fully automatic finishing operations in the rotary vibrators of the model range CB, especially with interlinked systems. It helps not only to minimize manual process control but also increases the overall process safety. For the suppliers of mass finishing equipment so-called ‘cup-shaped’ castings can pose major challenges: upon completion of the finishing cycle such work pieces, for example battery housings, can contain a certain amount of processing media, which might be carried out of the machine with the work pieces. This can pose serious problems with downstream manufacturing operations. That is one of the reasons, why Walther Trowal developed the SZ-Plus control panel for the CB model range, which was introduced to the public at the Euroguss 2018 exhibition. It covers the entire surface finishing process including automation stages like work piece loading, the finishing step itself, discharging of the finished parts from the machine, work piece drying and work piece transport before and after the finishing step.
Figure 1: The mass finishing technology can be used for surface grinding, smoothing and polishing as well as for deburring of castings.

Figure 2: The processing media is safely removed during the separation phase, even from “cup-shaped” parts.
One major feature of the new control system is that, compared to the actual finishing step a higher vibratory amplitude can be programmed for the screening step, i.e. the separation of the finished work pieces from the media. This greatly facilitates the removal of media, which might have been carried out of the finishing machine by cupshaped work pieces (Fig. 2). The new control system helps automate finishing processes and eliminates many manual operations like, for example, the manual adjustment of the machine settings. In the program library the processing parameters can be easily selected for a wide variety of different customer work pieces. The new panel controls not only the timing of the different process stages but also ensures that compound and water are injected into the machine at the precise required quantities. This helps prevent operator errors and ensures absolutely constant and high finishing qualities. The CB rotary vibrators allow the processing of castings with dimensions of up to 380 mm (15”). Of course, they can also be used for finishing other high value work pieces that are processed in multi-stage processes with grinding and polishing pastes. This includes so-called “Trowapast” processes, which are employed for stainless steel work pieces and even, components made from ceramic. For further information: www.walther-trowal.com

steels, according to customers needs), supplied by our partner foundries. In terms of machining activities, we produce in-house about 70% of our total volume. The rest of the production is entrusted to external partners with which we have consolidated relationships.” After machining, the production process continues with a cleaning, rinsing and drying cycle of pumps’ individual components, the assembly of pumps, and the coating and packaging stages. “We chose not to clean our products after assembly and before coating because their morphological characteristics are not suitable to such a process at that production stage,” states Donato Marchi. “We clean and treat the parts contaminated with machine tools’ lubricants and machining shavings in a continuous flow basket tunnel, performing a phosphodegreasing, two rinsing, and

Unlike cleaning, the coating phase takes place after the assembly of pumps. The operative choice to coat the products after assembly results in the impossibility to use powder coatings, because thermosensitive components, such as rubber gaskets, would not withstand the high polymerisation temperature.” Coating: a complex phase Unlike cleaning, the coating phase takes place after the assembly of pumps. This ensures film uniformity and good aesthetic quality finishes. “We cannot paint individual components due to our projects’ peculiarities,” states Donato Marchi. “The operative choice to coat our products after assembly results in the impossibility to use powder coatings, because thermosensitive components, such as rubber gaskets, would not withstand the high polymerisation temperature. It is also important to note that the coatings applied on our pumps must be compatible with drinking water contact, as required in numerous applications. We therefore need to use coating products certified according to the Ministerial Decree no. 174 for Italy, the WRAS approval in the UK, the CS approval in France and the KTW 270 certification in Germany.” “Our requirements to our coating suppliers are therefore complex: we need a product that can be applied with robots, is anticorrosive, ensures salt spray test values of at least 600 hours, dries in the required time, and is certified for drinking water contact,” states Giovanni Rizzati. “For all these reasons, after using a one-layer water-soluble system during the 1990s, we switched to a mixed system featuring a two-component solvent-based primer, surface tolerant and with good corrosion resistance properties, and a two-component water-based epoxy enamel. When we examined the project of the new coating plant with Trasmetal, we immediately clarified that the process had to be perfectly fine-tuned for the products already in use, since this mixed cycle has allowed us to meet the increasingly high quality requirements of the sector for some years now.” For the Caprari Group, coatings are applied primarily for functional reasons: they must be certified for drinking water contact and give the products the corrosion resistance required. Secondly, there are also aesthetic reasons, since nowadays the look of any kind of product must convey the perception of a high quality object (Fig. 3).

The realisation of the new plant For its new coating plant, Caprari imposed the following requirements to Trasmetal: 1. It had to accommodate a larger average physical dimension of pumps than the old system – designed and built twenty years ago according to the production needs of that time, it had a maximum load capacity of 250 kg per hook and a size capacity of 800x800. 2. It had to ensure better quality results, because the use environments of pumps are increasingly harsh, water

Each product to be coated is identified by a barcode. Thanks to CMA’s software, the operator reads the barcode on the tag applied on the pumps from assembly to packaging, and the monitors installed on a pulpit in the loading area display pictures of the incoming workpieces and their related hanging and masking detailed instructions (Fig. 7). The software program matches each part code with a hook; the operator confirms the loading operation is finished and starts the cycle. At the booth’s entrance, the system reads the load bar number and the barcodes associated with each hook, enabling the robot to select the coating program corresponding to each product and proceed with the paint application (Fig. 8). A 4-spot buffer was created in front of the primer application booth. When the cycle time of a load bar ends, the software program opens the booth and the robot identifies the following workpieces. A flash-off station performing a 48-minute process at 40 °C is located between the primer and enamel application booths. The load bars exiting the former are transferred alternately to the right and left lane to allow the flash-off phase to take place for the time needed even in a small space (Fig. 9).

produced by the afterburner. “When designing this plant, we primarily focussed on its ecological aspects,” states Dario Zucchetti from Trasmetal. “The coating cycle adopted was not completely water-soluble, which would have allowed for the emission into the atmosphere of the air from the booths. Given the mixed cycle employed by Caprari, it took us a long time to design the air treatment system in order to comply with regulations and at the same time achieve the main goal of energy efficiency. Once we decided to use automatic booths with an air recycling system, we had to find the most
technologies as well as activated carbons. Of course, the choices made for the emission treatment operations affected other plant engineering decisions.” “After assessing different options, we chose to install an energy recovery thermal afterburner without any concentrator to limit emissions (Fig. 13). This resulted in the need to limit airflows, too, and to use high concentrations of solvent in the booths (not more than 2 gr/m3). Consequently, both booths were conceived as completely automatic machines with an air recirculation system. The air

It consumes half the energy it would have required, for instance, with a ceramic afterburner and a curing oven, each with its own burner. Clearly, this choice is closely linked to the automation of the coating process, because no operator can access the booths due to the high solvent concentration in the air.”

emitted from the booths flows into the afterburner and the heat generated by the solvent combustion is completely recovered and used to heat the curing oven. The whole system, therefore, works with one burner,” explains Dario Zucchetti. “The overspray issue, on the other hand, was easily solved also thanks to Caprari’s experience. We opted for continuing with dry filtration.” A system structured like that of Caprari Spa, as well as fully complying with VOC regulations, enables to save energy. It consumes half the energy it would have required, for instance, with a ceramic afterburner and a curing oven, each with its own burner. Clearly, this choice is closely linked to the automation of the coating process, because no operator can access the booths due to the high solvent concentration in the air. “When an operator needs to enter a booth, for example for the robots’ self-learning programming operations, it is possible to open it and activate the direct air expulsion system,” says Zucchetti (Fig. 14). “From the operational point of view, however, we realised that it is easier for the operators to assess the products’ coverage by the robot in the enamel application booth, since most of our workpieces are already coated with a foundry primer in an oxide red colour identical to the one we apply.

Moreover, each product is subjected to control procedures at all stages of manufacturing as proven by our ISO 9001 certification, an international certificate of conformity guaranteeing the presence of an optimised organisational structure and processes of adequate quality.” Finally, for several years FANTIN has been supporting an ethical project for strict compliance with all environmental requirements at every stage of the production process, thus respecting the environment and manufacturing 100% recyclable furniture.
The key role of pre-treatment for optimal coating operations “FANTIN’s new business strategy,” says Rango Fantin, owner and paint shop manager, “is centred around medium-high-end furnishings combining sturdiness and durability with aesthetically pleasing coatings. This can only be achieved with a perfect balance among machining, surface preparation and paint application. That is why we paid particular attention to the pre-treatment phase: it is often seen as secondary, but for us it plays a key role.” FANTIN has cooperated for over ten years with Kemmex, a supplier of chemical products for substrate preparation and consulting services on process optimisation. “During our partnership with FANTIN,” says Gianni Zilli from Kemmex, “we have switched from the supply of liquid products to that of high performance gel formulations: thanks to their higher concentration degree, these enable to work with smaller quantities of product and therefore create a lower risk of tank pollution. Moreover, the correct dosage

FANTIN’s new business strategy is centred around medium-high-end furnishings combining sturdiness and durability with aesthetically pleasing coatings. This can only be achieved with a perfect balance among machining, surface preparation and paint application. That is why the company paid particular attention to the pre-treatment phase.” of high yield gel formulations used in synergy with a special highly degreasing additive based on surfactants and solvents enabled FANTIN to solve a major pre-treatment issue: the cleaning of metal sheets heavily contaminated by the difficult-to-remove oils necessarily used during processing.” “Solely following the addition of this particular additive in the appropriate doses,” says Rango Fantin, “we noticed a marked improvement in the workpieces’ cleanliness. This might be trivial, but sometimes it is sufficient to dose the chemicals correctly to achieve maximum efficiency in the pre-treatment process and therefore good-looking end products. And this is a crucial factor, especially at a decisive business stage such as our current attempt to gain a new slice of the furniture market.” The use of specific pre-treatment products also allows to remove contaminants from welded areas and give them the same film adhesion properties as the rest of the component, thus achieving © ipcm ®
100% coating conformity. “Sometimes,” adds Rango Fantin, “our salt spray test results were positive for some parts of our workpieces, whereas the surfaces near the welded areas presented problems of coating detachment. Therefore, together with Kemmex, we carried out a research study to develop a pre-treatment cycle ensuring a homogeneous degree of cleanliness on our 4 1

furniture through colour is a trend that is increasingly spreading and resulting in pressing demands from our customers. After a research study on the new trends in the fashion world, we have had 23 unusual RAL colours produced for the market. We were surprised that the coating manufacturers we contacted were available to produce even only small batches since, only until recently, it was necessary to order fairly high minimum quantities. Perhaps, this is a sign that also the relations with paint suppliers are changing radically. As FANTIN needs to align its production capacity to the functional and aesthetic concepts of designers and architects and to understand their requests, so the coating manufacturers grasp the applicators’ needs and meet them by offering innovative shades and effects that will become the future trends of the market (Fig. 6).” During 2018 FANTIN will add some new home furnishings to its catalogue, e.g. cupboards, tables and kitchens with metal components in different colours, and it will advance along the path of internationalisation in order to make known and distribute its

Figure 1: Dörken MKS-Systeme developed a bulk cataphoresis process called DELTA-eLACK® with a drum system.
Due to the characteristics of the cataphoresis process itself, requiring the workpieces to be hung onto frames, bars or skids, until some time ago it was unthinkable – or at least too burdensome in terms of labour and process times – to use cataphoresis to coat very small parts such as fasteners, screws, bolts, pins and washers. On the German market, the cost per cataphoresis-coated component is 3 to 10 cents (calculation based on the dimensions and size of parts). That is why, despite its exceptional strength and aesthetic properties, cataphoresis was never used as an anti-corrosion treatment for bulk small components. Dörken MKS-Systeme, a company based in Herdecke (Germany) and a leading manufacturer of zinc-lamellar anti-corrosion coatings, developed a bulk cataphoresis process a few years ago. It is called DELTA-eLACK® and it enables to coat small-sized components with a drum system (Fig. 1). Metallveredelungswerk Sulz GmbH (Sulz am Neckar, Germany), specialising in galvanic, zinc-lamellar and anti-corrosion coatings, was one of the first companies to implement the new DELTA-eLACK® process offered by Dörken by developing an eco-friendly treatment cycle. This ensures high anti-corrosion protection performance and the application of a black layer of uniform thickness on fastening parts intended for the

because molecules in these materials absorb photons whose light is of one frequency while spontaneously reemitting higher-frequency photons, which also carry more energy. Since energy is lost, the temperature of the material is reduced in the process. “Heat from a building could be absorbed and re-emitted as light,” Yaron Shenhav says. “As long as the sun is shining on it, it would be continuously cooled.” The problem is that the sun’s spectrum is much broader than that of laser light. SolCold’s team had to create a material that could do the same trick using several frequencies of scattered light. The result is a double-layer paint with an outer layer that filters out some of

Simulations show that a room on the top floor of a house with the paint applied to the roof will feel up to 10°C cooler than of a house without the coating. According to SolCold, commercialization is due in about 1.5 years from now. © SolCold
In recent years, the increasing focus on the environment, together with the need to reduce the energy costs, has prompted the manufacturers of paints and coatings for metal to seek solutions for allowing to reduce the energy consumption. One example are the painting products for the so-called “cool roofs”, with which it is possible to considerably reduce the temperature of the interiors below. This kind of paint, mainly used for pre-painted metal, reduce the amount of heat that buildings absorb, but they can’t actively reduce the temperature in the building, whereas SolCold’s paint can.
How does it works? The technology is based on the counterintuitive principle of laser cooling, in which hitting specially designed materials with a laser can cool them by up to 150°C. It works

There was also the requirement of the conveyor having the capability of raising and lowering product within the spray booth and at the inspection area whilst allowing the operator to rotate the unit during the spray process. A multi height drop section at the inspection area allowed the operator to inspect the product thoroughly prior to despatching to the appropriate unload stations. In order to achieve all of SEW requirements, the system was designed with 2 loading stations having a stationary trolley set assembly in position that would allow the operator to attach the product onto the trolley load bar support points, smaller products being suspended from any of the rotation units on the load bar, whilst larger product would be suspended from the central rotation point. The operator at either of the two load stations scans the product(s) and then presses a button at his work station that determines if the loaded trolley is to be routed to normal business, colour or Fast Track. When the trolley arrives at the storage lanes, the conveyor switch point automatically diverts the trolley into the appropriate storage lane. A monitor within the spray booth allows the operator to view the jobs in hand, allowing him to select from the appropriate lane. The Fast Track lane can by-pass accumulating daily business enabling the unit to be painted without being held up by normal business. With the trolley now in the spray booth, the operator can lower the drop section as required to an ergonomic height due to the differences in product size to allow him to spray all the relevant aspects of the product whilst remaining stationary (Fig. 2). The load bar assembly was designed such that the products can be turned through 360 degree during the spraying operation and then locked after the spray operation to maintain correct product orientation. A major benefit of the drop section ensured that lowering of the product could be achieved within a small area compared to that of a conventional conveyor rise and fall. With the paint spray process now complete and the drop section in the raised and locked position, the operator again

Upon exit of the main curing, the trolley set complete with dried product would then be automatically diverted either into the normal business line or routed to the “fast track” lane. Products that are deemed for daily business would be diverted into a storage loop which in turn then continues to travel to the multi height inspection drop section, but trolley sets that are deemed as Fast Track (urgent orders) do not enter the normal business loop, these are diverted directly to the inspection drop section. The loaded trolley set is again stationary for the inspection process allowing the operator to raise and lower the product together with rotation through 360 degree for full inspection. Upon completion of inspection the operator determines if the product is to be transported to unload station 1 or 2. And the inspected unit is now

Central Europe to DECHEMA, appropriate protective measures could save up to 30 percent of these costs, amounting to approximately US$ 1 trillion every year. These figures clearly indicate that today corrosion protection is an issue that cannot be ignored. Nonetheless, established methods of surface treatment, including chromating and phosphating, are increasingly coming up against limitations and are seen ever more critically, mainly for reasons of environmental protection. Application techniques for substances containing chromium (VI) are particularly problematic. The use of these substances is being banned in Europe in an increasing number of applications, through such provisions as the second RoHS Directive (Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment), which came into force in 2013. The US, Japan, China, and South Korea have adopted similar regulations. Alternative methods for protecting metal surfaces against corrosion are therefore urgently needed, and these methods

Evonik’s developers rely here on hydrolyzed and condensed silanes that form a binder: the formulation of such binders results in eco-friendly corrosion protection systems. During the curing process a protective film with a thickness in the nanometer to micrometer range is formed; although thin, the film is highly impervious and protects the underlying metal against water and corrosive substances. It can be formulated using other binders and fillers to form thicker corrosion protection systems. In recent years, Evonik’s specialists have developed, under the Dynasylan® SIVO brand name, a series of binders that have proved their worth in a very wide range of materials and application methods.
Environmentally friendly zinc dust paints Paints with an underlying zinc dust primer are the means of choice when long-term corrosion protection is called for and other coatings have reached the limits of their capabilities. Typical application areas include transmission towers, industrial plants, bridges, and shipbuilding. The zinc dust in the paint is deposited as a fine film on the surface of the materials, the particle density being so high that the individual metal particles are in contact with one another. The electrically conducting film so formed then serves as anodic i n f o @ w a t e r e n e r g y. i t w w w.w a t e r e n e r g y. i t

It may nevertheless be necessary to provide even these metals with additional corrosion protection if, for example, they come into contact with chloride. Corrosion inhibition primers based on Dynasylan® SIVO 160 are particularly suitable for protecting materials like aluminum, magnesium, and zinc-galvanized iron or steel against corrosion (Fig. 1). In contrast to the current solutions employed in this area, the binder contains neither heavy metals nor fluorides, which are highly objectionable from an environmental viewpoint. These additives are also not required in the formulation of the actual rust inhibition primer. A film thickness of just 100 to 200 nanometers of this water-based silane system is all that is needed to protect aluminum from further corrosion. For use in exterior applications, the system is formulated with additional additives 1

ORGASIL 01® maintains its stability within a certain pH range (5 to 10): if the pH value falls outside this interval, the organic silanes irreversibly hydrolyse and they are no longer available for the creation of the nanometric coating; it will therefore be necessary to change the bath. That is why it is necessary to make sure that the pH of the bath is as stable as possible. This can be done through some precautions, such as the increase in the number of rinse stages to avoid the dragging of products that can alter the pH value (as in the case of Colortec’s pretreatment process) and the optimisation of the dripping stage required among the different phases, providing for suitable time and space for the conveyor movement.”

Production progress control through a PLC The case of Colortec proves that the human-machine relationship is still crucial to better manage the material and labour resources available. The Colortec’s operators take charge of the incoming orders and selects the right pre-set treatment programs based on the customers’ requests (Fig. 17). There are different parameters to be set, such as pre-treatment specifications, RAL colours, number of bars, and amount of powder to be used. Once the required data are entered, the operators start the production process following all the parameters selected. They simply need to enter the indicated values on each management device of the plant. When the processing cycle ends, the customer is notified by e-mail that its order has been completed; in case there is any problem or surface defect, the system immediately detects it and the notification is blocked until the issue

The quality and resistance of the coatings are constantly praised by the customers, whether it be the companies installing and using the Eurotherm’s systems or firms entrusting Colortec with the coating of their products.”
Conclusions “Colortec,” says Ghiazza, “works in 3 shifts for 5 days out of 7. This results in a sustained production flow, which took time to be optimised and which can certainly be further improved. However, we know that we are moving in the right direction, especially because numerous operators in the sector, above all customers from France and Germany, visit our plant in Volpiano

intermediate steps such as grinding and puttying are still required in order to produce a class A surface. On the other hand, electrochemical corrosion at the edges of the CFRP components needs to be avoided, which can occur after processing if freestanding carbon fibres come into contact with metallic components. Various projects dealing with these issues are currently in progress with the goal of, amongst others, developing a process for appropriate edge sealing.

Highly Efficient Painting Processes Filler-free painting is not entirely new, but it’s still highly relevant. The function of the filler coat is usually implemented by means of a waterbased paint system for this so-called integrated concept. Depending on appearance, hue and the quality levels which can be achieved with the filler-free process, the conventional process with filler, basecoat and clear coat is the more

without intermediate drying. Speaking of appearance, the current trend is moving towards more and more polychromatism and individualised painting. The goal is to be able to paint without masking and to significantly reduce required time and effort. Painting without masking has already been implemented in the aviation industry for tail fin coatings, to which decoration has been added without any overspray through the use of individual droplets. Spray film is another approach which can be applied with a very sharp edge and simply pulled back off again later.

A new conveyor system which transports auto bodies through the paint shop without any skids makes it possible to reduce energy costs, because skids no longer have to be warmed up and cooled down.â&#x20AC;? A new conveyor system which transports auto bodies through the paint shop without any skids makes it possible to reduce energy costs, because skids no longer have to be warmed up and cooled down (Fig. 1). Furthermore, this increases the flexibility of the painting process because speed can be adapted to the respective process step. Cycle times and throughput can be laid out flexibly and optimised in this way. Decorative and functional parts for the vehicle interior, as well as trim moulding such as pillar trim in proximity to the body, are usually manufactured by means of plastic injection moulding. The surfaces of these components are subject to highly individual requirements with regard to optical and haptic characteristics, as well as durability. These requirements can be fulfilled with the help of advanced solutions based on the RIM curtain coating process. The two paint components are injected into the mould during the reforming or in-mould decoration process. If colour is added as a third component, 3-component mixing heads make it possible to inject it directly at the part, and colour changeovers are just as fast and simple as with spray painting. Coated components can thus be manufactured by means of a one-shot process. In the case of conventional spray painting of plastic parts for the vehicleâ&#x20AC;&#x2122;s interior, one-coat systems decrease the number of process steps, thus resulting in increased throughput in addition to time-savings and reduced material consumption. Newly developed paint systems are also available for the protection of fine wooden dĂŠcors. Top coating can thus be completed in roughly 3 hours - using either a manual or an automated spray painting process. As compared with previously used systems, this represents time-savings amounting to 5 hours, which constitutes a considerable increase in productivity.

Where application is concerned, processes which permit coating without any overspray, or with significantly reduced overspray, are the goal. Until solutions of this sort are actually available, highest priority is assigned to increasing paint application efficiency. Companies make use of various optimisation potential to this end, for example modification of the air control units and rotating bells, as well as spray jet adjustability (Fig. 2). Thanks to their flexibility, these atomisers

The air in the paint booth can be recirculated to a great extent in this way. Furthermore, dehumidification of the air as required for wet scrubbing systems is eliminated and the energy consumed for this purpose can be saved.

It was developed during the course of a research project and makes an automatic painting process possible in five steps: First of all, the object to be painted is scanned three-dimensionally and a fluid-dynamic simulation is created on the basis of the scanning data. The trajectories of the paint droplets are ascertained and the ideal paint and air quantities for the desired layer thickness are determined. As a third step, the system works out the best possible robot path for the painting process on the basis of these data. This is followed by the actual painting process, after which quality inspection is conducted as the fifth step through the use of terahertz technology.

evaluate the results of accelerated weathering? Visual effects such as chalking, blistering or rusting are obvious and straightforward, as there are corresponding ASTM standards that can be used to guide these evaluations. Less visible property changes such as sensitivity to moisture can be evaluated by a hardness test or solvent resistance. One of the more comprehensive methods is the evaluation of barrier properties using electrical impedance spectroscopy (EIS) or other electrochemical means. EIS involves applying an AC potential to an electrochemical cell, and then measuring the response. The result is the

change in resistance, as observed by change in magnitude and phase shift. Note however that detecting changes in barrier properties of coatings that are 15-20 mils or more using EIS can be quite time consuming and require long term exposures.
Conclusion: everything is relative. Just like every being on the planet, we are somehow related, and yet unarguably unique. Every service environment has a completely unique “DNA” of circumstances that will drive you crazy trying to replicate. Side-step the confusion by relying on low-end and high-end performers of known durability in all your exposure tests, and the required duration will reveal itself. Instead of searching for the perfect exposure regime and the ideal duration, save the frustration for another project, and break down the opposition into components that you can precisely measure and control.
