Dulux launches Colour Sensor

SAPMA AGM- tackling important issues

OCCA: An overview

Technical Article

Half-measures don't work! The more things change, the more they stay the same. We are approaching the final days of 2021, but it feels as if I have been taken back in time. It was almost a decade ago, that I first listened to Dr Mathee speaking at a SAPMA meeting about lead in paint. Why it was dangerous and how the industry needs to eradicate its use in coatings. But the South African government implemented a half-measured approach. Lead was bad for certain applications, and fine for others. What a mess. Now, lead is back in the spotlight. This time around the legislation is much tougher. However, as Tara Benn, executive director of SAPMA, rightly says in her letter this month – the proof is in the pudding. It is all fine and well to have legislation, but if it is not enforced – then it is not worth the paper it is written on. I call on members of our industry to hold each other responsible to ensure we create a better environment for our communities. Hold your colleagues accountable if they transgress – this

ed’s note

is good business practice. The next thorn in my time machine – load shedding. How is it that it has been nearly 15 years since the first time Johann Gerber we experienced load shedding, and the problem has not improved? I am dumbstruck. And my positive self has left the building. My fellow colleagues of this wonderful industry, we must do what must be done to ensure we survive. I have no message of positivity – there is none. Run your businesses as efficiently as possible, navigating the dreaded load shedding, and position your brand and product as well as you can to survive. All we can do is pray that we will jump two decades into the future and find our industry in a more certain position. I trust you will all have a strong end to the year and enjoy the short industry break before we tackle 2022. Happy Trading

Message from the Executive Director

New leaded paint laws are great – but will they be enforced? By Tara Benn SAPMA welcomes the news that the government has decreed that, from 22 October 2022, lead will virtually be a banned component of coatings. The new legislation was announced by SA Minister of Health, Dr Joe Phaahla, in the Government Gazette, in October 2021.

he new technical laws shift the classification of leaded paint under South Africa's half-century-old Hazardous Substances Act, and effectively changes the legal definition of leaded paint. It follows decades of lobbying for the removal of lead in paint by SAPMA in collaboration with the Medical Research Council. Back in mid-2010 already, South Africa declared leaded paint as a Group I Hazardous Substance, but with exceptions. Paints with lead at a level below 600 parts per million were then not affected, and there were exceptions for paint used as industrial coatings, garden equipment and some toys. The new rules will now totally ban paint with lead above 90 parts per million (0.009%, instead of 0.06%) – and apply to all ‘paints and coating materials’. Dr Angela Mathee, director of the Medical Research Council’s Environmental Health Research Unit, has told the press that the new law is ‘tantamount to a ban on the addition of lead to paint’.

SAPMA is delighted with the new legislation. But we have one major concern: we want to see whether – and how effectively – the government will police the new regulations. We have for many years urged the authorities to start prosecuting unscrupulous paint producers who blatantly included hazardous lead

SAPMA is convinced that the new legislation will only be effective if the government make examples of culprits and prosecute them.

levels in their paints. We have urged that retailers who sell such paint be taken to court. Random samples taken from hardware shelves by the government regularly showed that hazardous levels of paint were still being sold. But that was that. No report of any offender being charged by the police appeared in the press. SAPMA is convinced that the new legislation will only be effective if the government make examples of culprits and prosecute them. In fact, why wait until the new laws become effective in October next year? Start arresting offenders who are transgressing even the current limits. Do it now. Such action would justify the costly and time-consuming efforts our members have made to comply with ethical policies in terms of leaded coatings. Many members, producing South Africa’s major brands, have for some years now already eliminated lead in decorative paint, and have diligently worked towards the total elimination of lead in the manufacture of paint, including industrial products such as road-marking paint. But these members have not heard of any prosecution of competitors who arrogantly flaunted – and are still flaunting – the country’s laws. So, SAPMA must be forgiven if we are not yet shouting from the rooftops about the new laws. We first want to see culprits in court. The only way to show offenders that the government means business, and will enforce laws relating to leaded paint, is to nameand-shame the criminals. And this should happen in massive metros or tiny towns where lead still goes into paint cans. c Tara Benn Executive Director

Discover Clariant’s new Licosperse Licosperse, a new product line from Clariant, is heavy metal and resin free, non-toxic, and non-flammable, recommended as a sustainable replacement for oil- and solvent- soluble dyes. Its ready-to-use blends save time and cost in the colouration process.

lariant has expanded its contribution to sustainability with the launch of its new product line, Licosperse, eco-friendlier pigment preparations for polish applications. To simplify use in the end user’s manufacturing processes, the preparations are produced with non-toxic raw materials, are non-dusting, and are heavy metals and resin free. “The pastes are readily incorporated in the base media for the effortless production of consistent colour. They can also be incorporated at high temperatures as the production method requires. There are no dangerous goods restrictions for transport and storage, reducing the risks in product handling and transportation,” said Rossitza

Dimitrova, Clariant’s regional technical marketing manager, Middle East and Africa. Licosperse preparations are recommended as alternative colourants to replace dyes in solvent and oil- based applications such as shoe and floor polishes, fertilisers and herbicides as well as wood stains and varnishes. Further application areas are expected in the future. With improved durability and low-migration properties compared to traditional dyes, which in many cases need to be pre-dissolved, the new pigment preparations are easy to incorporate with no need to pre-dissolve. Licosperse pigment dispersions are providing a competitive advantage

to customers. As a single product that is applicable for many different applications, the ready-to-use blends save time and costs in the colouration process. Colour recipes for popular shades are readily available, for easy integration into most systems and simplified quality control. This new line supports Clariant’s objectives to ensure that products meet international environmental, health and safety performance standards. The company’s organic pigments and colourants have a global reputation for technical performance and high quality. c For more information, visit www.clariant.com.

Vice-chairs call for stronger support SAPMA has elected Bobby Bhugwandin and Stephen Reinecke as joint vice-chairpersons for the year ahead. Both new office-bearers have emphasised SAPMA’s vital role in the coatings sector having a unified voice.

hugwandin, a SAPMA stalwart, is currently the supply chain director for Kansai Plascon, overseeing all manufacturing plants, warehouse and distribution, procurement, SHERQ and forecasting. His first introduction to SAPMA was serving on the Technical Committee, first representing Plascon and then chairing the Committee for two consecutive years. In addition, he has also served on SAPMA Executive Committee for a few years. His career in the coatings industry began straight from college at Dulux, where he worked for 13 years in Research and Development. This was followed by two years at Synthomer before joining Kansai Plascon 13 years ago to fill various roles such as senior executive – Research and Development, and general manager of the Kansai Colourants business, prior to his appointment as executive director in 2018.

Bhugwandin is passionate about unity. He explains, “All industries need a representative body to take on industrybased challenges. Together, our voice is stronger, and this becomes critical when dealing with government and other stakeholders on issues such as regulation, tariff conditions etc that will affect the viability of the industry and ultimately the survival of many individual companies. Coatings plays a vital role in the South African economy and for it to grow and survive, we need a unified body such as SAPMA to represent it at the relevant forum,” SAPMA’s other new vice-chairperson, Stephen Reinecke, in 1991 co-founded and became Director of Promac Paints, SAPMA members for several decades. He has served on the SAPMA Executive and Management committees for the past two years. With 30 years’ experience in the paint industry, Reinecke is an ardent SAPMA supporter. “SAPMA, for me, remains

to be a critically important forum, voicing the coatings sector’s stance in communicating with government, industry, the public and the exchanging ideas of business practices between members. I believe every member must have a key representative, attending to all meeting and SAPMA matters timeously. “Members surely cannot be satisfied with decisions from poorly attended forums and meetings. SAPMA’s voice needs to be collectively represented – by at least 80% of its members. The need for retailer and contractor membership is extremely important to strengthen our industry’s image, Health and Safety status and, most importantly, our environment and integrity. The unity and collective contribution by all members, and securing many new members, will strengthen SAMPA to a healthy balance of industry representation,” Reinecke adds. c

We need unity in turbulent times For the past 11 years, Sanjeev Bhatt has served as joint vice-chairperson for SAPMA. He has been elected to take over the reins of the association from Aggie Argyrou.

ounder and managing director of resin supplier, Synthetic Polymers in Krugersdorp, Sanjeev spoke about his role in SAPMA and the way ahead:

When did your involvement with SAPMA start? It started way back in 2007 when I convinced my employer at the time to become an Associate Member.

What inspired you to join?

At the time I was employed by a relatively new company that had invested in South Africa in 2001 and had heard a lot about SAPMA and its activities in the local coatings market. It seemed the perfect platform for a new entrant to the industry to understand the market dynamics and be part of a robust coatings market.

Post-Covid, not only the coatings sector, but the entire manufacturing base in South Africa is facing immensely turbulent times. Local problems such as Eskom energy constraints, electricity tariffs, and the cost of labour have compounded already existing issues of high freight rates and extended shipping and logistical delays.

South Africa to other big economies in Africa, such as Egypt and Nigeria? To ensure fair trading conditions is an important facet of SAPMA’s role to lead the industry and maintain a healthy manufacturing base.

What do you see as the major challenges facing the coatings sector now – and in future?

BP006.pdf

tariffs have soared by almost 300% and frequencies between various important ports are now operating 50% lower than before the pandemic. Manufacturing locally is challenging and government policies are not assisting to alleviate the pressure. How would SAPMA be able to play a role in leading the industry in this regard? It is very difficult for individual companies to lobby with government stakeholders on their own. Working in isolation will not help. The only way we could achieve our goals is being collective through the auspices of SAPMA. As an association that is over 80 years old, SAPMA has experience in lobbying government to institute policies conducive to the coatings sector locally. The African Free Trade Agreement is a classic example: sure, it’s good to open free trade across the African continent, but are the playing fields level when we compare

What are your personal aspirations in terms of SAPMA? How do you see the association, say, in five years’ time? As a core focus, I would like to see membership increase and members become more active. Moreover, we should also broaden the membership base to include many more retailers and contractors. And try and revive the training of young chemists and ensure true empowerment and transfer of skills. An organisation is only as good as its members. With unity and increased involvement by all members, SAPMA’s future is assured and membership will become even more meaningful. c

These are colours that bring in the positive effects of nature to create a vital space. Studio colours (consoling tones) Pale pinks, reds and oranges, these warm, consoling shades can help turn any space into a soothing sanctuary. Subtle and inspiring, they can help us recharge and escape the everyday.

SAPMA 2021 AGM report The Coatings Confederation – There’s little doubt that the sustainability and impact of SAPMA will be dependent on the effective formation of a broad-church or organisations, which together with SAPMA can maintain a healthy and progressive Confederation for Coatings in South Africa (CCSA). By Dr Ivor Blumenthal To this end, SAPMA has resolved to: • Create and register this confederation with SAPMA as its Patron • Ensure that for the industries included within the scope of the confederation are either active and wish to participate within the confederation, or need to be established under the ambit of SAPMA.

Industries currently included in the Coatings Confederation which SAPMA would be responsible for: • The SCEA • Retail Paint & Hardware Association

The Surface Coatings Employer Association Report • Currently the SCEA represents 17 out of the full complement of SAPMA’s Membership. • The SCEA is a party to the National Bargaining Council for the Chemical Industry.

The SCEA has negotiated a role as a party within the NBCCI which results in: • A sectoral addendum to the main agreement for the Industrial Chemical Chamber of the NBCCI, specifically for surface coatings relating to Wages and Conditions of Employment • A moratorium for four years preventing the extension of any NBCCI agreement to SAPMA Members who currently are regarded as non-parties • An agreement with the NBCCI that on a voluntary basis, SAPMA can offer its members NBCCI membership designed to ensure that those members do not have to enter into individualised plant based agreements with trade unions, and access to the NBCCI Dispute Settling Mediation and Arbitration Services so that SAPMA members do not have to appear before the CCMA without representation. On this basis any annual agreement reached by the SCEA constituting the addendum would need to be applied by those SAPMA members.

The Retail Paint & Hardware Association This Association has recently been registered by SAPMA. It is designed to cater to retail members of SAPMA who require a collective voice where two structures are currently being created by two different government departments: • A Bargaining Council for The Wholesale and Retail Sector by DE&L • A Wholesale and Retail Charter Council by the DTI&C

THE SAPMA CERTIFICATION MODEL The South African Paint Manufacturing Association is launching an Internal Member Accreditation Service, designed to cater for the recognition, registration, and quality assurance of two specific organisational initiatives amongst a section of SAPMA’s members. Firstly, training and development of staff within the paint manufacturing sector has become so specific in many instances, especially in relation to product designed for customised market requirements that internal training has had to be developed and, in some instances, accredited in South Africa or through multinational arrangements in other countries. In some instances, the motivation in offering internal training has to do with strategic advantage and market presence. The requirement from those members who have internal training departments, is for those divisions to be registered, assessed, and recognised against a National Standard. Once identified, SAPMA members that engage in internal training and competency certification, will collaborate with SAPMA on a collective standard of training,

development and certification which all SAPMA-registered internal training departments and activities will ascribe to and follow. SAPMA maintains that the national standard must speak to the training division itself in terms of structure, administration and quality control. Once the actual administration of training is dispensed with and recognised, the focus shifts to the quality of the training programmes themselves, including the credentials of those offering the training as well as those assessing competency. What should be attractive to SAPMA members, in this regard, is that the final certification offered to those who complete the programme, would be done in association and partnership between the registered member company and SAPMA. The second SAPMA initiative relates to the registration, recognition and endorsement of internal laboratory services for product certification amongst our members. Once identified, SAPMA members that engage in internal product certification, will collaborate with SAPMA on a collective standard of certification, which all SAPMAregistered internal laboratories will ascribe to and follow. Where a SAPMA member company has elected to implement internal product certification using a standardised nationally recognisable system, SAPMA would encourage that company to register this activity with it, so that the division within the company can be assessed and recognised by SAPMA for this purpose. This activity of recognising a member's internal laboratory services is not designed to bypass any SANAS accredited quality assurance process

Feature nor is it designed to represent that in SAPMA recognising an internal laboratory service, such recognition is offered in any way, in partnership with SANAS or that it confers any SANAS Accredited Status on the company being recognised for this purpose.

What is, however, accomplished, is that the self-certification of product by the SAPMA member company, which is permitted by the SABS and SANAS by-way of affidavit, is reinforced when the internal laboratory service is registered,

quality assured and recognised by SAPMA. The self-certification will certainly have more credibility because of the level of accountability to SAPMA. SAPMA will endeavour to formalise its quality assurance activities in this regard with the respective regulators ASAP. THE PROFESSIONAL BODY PILOT PROJECT The Coatings Confederation will be introducing professional recognition for employee’s covered by the scope of the confederation. SAPMA will commence the exercise with retail members of SAPMA. Within the Retail Chamber (The Retail Paint and Hardware Association) SAPMA will be implementing the following professional designations for employees within retail establishments, in-association with the Canadian Retail Association.

THE PILOT PROGRAMME FOR SAPMA’S ‘PUBLIC ACCOUNTABILITY & ETHICS OMBUDSMAN’ BRANDING CAMPAIGN SAPMA has commenced with the advertising and brand building campaign about SAPMA members accountability to SAPMA in-terms both of trained and recognised professional competency and of behavioural accountability. This campaign will be replicated in provinces which currently represent inexcess of 15% of SAPMA Members. THE SAPMA TRANSFORMATION BAROMETER The DTI&C have impressed upon SAPMA the fact that for SAPMA to legitimately be the mouthpiece as a sectoral association, SAPMA will be held accountable for creating a Real-Time Dashboard of Gender and Racial Transformation for the Coatings Sector. Where there is a confederation

that burden will be placed on the confederation instead. It has been stressed that such transformation is required to be reflected not just in the economically active population amongst SAPMA’s members, but also amongst the management structures of members. Importantly, the same EAP Profile needs to be reflected amongst the office bearers of SAPMA. In this regard the DE&L has urged SAPMA to take responsibility for engaging on the Employment Equity Targets and creating an EE Profile for Coatings, which is acceptable to the DE&L for purposes of the certification of our Members for Preferential Procurement. The table below reflects the impact which the new DOL targets for the Construction Sector will have on coatings unless we are able to negotiate a sectoral profile more in-line with our actuals, than what the DE&L think is the case. Below find some of the DE&L views on how transformation needs to be implemented in the construction sector.

which SAPMA currently has a relationship, look to SAPMA to coordinate trade and marketing data for the benefit of STI&C and DE&L planning purposes. This information in-turn effects the nature, volume and content of supply-side incentive programmes, which are made available to our members from government as well as labour and import and export policy. SAPMA established a Hands-Off Research Programme with Boake, our auditors where at one stage we had 14 companies supplying information regularly and participating both in providing information and having access to the amalgamated reports when they were produced. Unfortunately, that number of 14 has now dwindled to less than five companies participating despite all assurances of confidentiality and anonymity having been provided and contracted by all parties concerned. As a sectoral body, SAPMA and eventually the confederation does not have the luxury of not completing this activity. A specific sub-committee will be meeting to ensure that this programme is revived. c

No alcohol is no solution either

By Udo Schonhoff, Carlos Feito, Frank Abschlag, Elke Piron and Sebastian Heinz

Marine and protective coatings typically have very high requirements in terms of sag stability. The systems are generally spray applied in high layer thickness of around 1000µm or even more in one pass. This high demand of the systems limits the selection of suitable rheology modifiers.

rganic thixotropes are providing the properties to fulfil this specific need. However, especially older classes of this technology have complex requirements in terms of incorporation and activation. Elevated temperatures, at a specified range, combined with high shear, for a defined period of time, in accordance with the system, which can be based on a manifold of binder chemistries and various solvent composition are required to achieve optimum performance (Figure 1).

As from a processing point of view, usually a batch-by-batch technique is used. External heating or cooling equipment is often not available so that active temperature control during processing is either not possible or only available at lab scale. The necessary energy to obtain and adjust the activation temperature is in such cases normally generated by friction during dispersion. The end temperature is dependent on parameters such as disperser speed and pigment/extender loading level and has a strong influence on the entire processing time. Therefore, rheology modifiers which are suitable for use over a wider temperature range show significant benefits.

to for example fumed silica, the low shear viscosity is much higher. With respect to practical relations this means that organic thixotropes are providing potentially the highest film build properties. On the other hand, fumed silica is providing higher viscosities at high shear rates. This effect often is adversely affecting the sprayability, especially the atomisation during the balanced anti sag performance.

For activation, the diamide based rheology modifiers need to be exposed to mechanical forces applied alongside with a specific temperature over a defined period. The mentioned activation temperature needs to be in line with the relevant solvency forces. PRODUCT CHEMISTRY After the activation, the rheological structure is built up by the molecules orientation towards each other forming a fibrillar structure due to the nature of the amide functionality as described in Figure 3. The driving forces for this process are intermolecular interactions such as hydrogen bonding- and van-derWaals forces.

COMPARISON TO OTHER THICKENER CLASSES Organic rheological additives provide outstandingly high low shear viscosity in combination with a strong thixotropic flow character in non-aqueous systems. As shown in Figure 2, in comparison

Castor waxes, the oldest class of organic thixotropes, require a similar processing, however, are much more sensitive to changes in the systems solvency forces and processing temperature. Further, they do not cover the entire solvent range. Additionally, they have a much higher risk of side effects such as seeding and false body. The latest class of diamide rheology modifiers, from the THIXATROL® PM and THIXATROL® AS series, allows the formulator to pull off robust and predictable processing under real life conditions when temperature variations often occur such as summer and winter. These products are applicable at markedly lower temperatures than traditional grades based on similar chemistries. This is of great importance in solvent-free systems where the activation temperatures are normally high. The main advantage of such low temperature activation is energy and cost saving in the manufacturing process. The process can be carried out without external heating and is faster. RESOURCES Also, from a sustainability point of view these kinds of rheology modifiers are very interesting. The new rheology modifiers out of the THIXATROL® product line is produced from renewable resources (>75% bio content). However, even with these major improvements by the described latest developments not all formulations could be covered. In systems of higher polarity, especially when formulating with various alcohols such as benzyl alcohol or butanol, a drop in efficiency in comparison with less polar systems is often the result. Alcohols are becoming

Technical more popular and are often formulated at higher concentrations to reduce aromatic solvents. In addition, they are also required to stabilise the system and to enhance the adhesion of the coating to the substrate. The new THIXATROL® PM 8058 has been developed to provide solutions exactly for this kind of formulation utilising higher amounts of highly polar solvents. Furthermore, THIXATROL® PM 8058 is significantly more effective than the other rheology modifiers in the THIXATROL® PM and THIXATROL® AS series. These improvements with THIXATROL® PM 8058 become obvious in the following model study in which a high solid epoxy-based primer of 83% solid content has been formulated with variating solvent ratios in comparison to commercially available reference organic thixotrope. In all case the concentration was chosen on a very level of 0.5%. This was done to emphasise the effect of the organic thixotrope at lower viscosity levels and to show the effect of the various solvent compositions on the viscosity build.

As visible in Figure 4, in the standard formulation the solvent part is dominated by the Xylene portion. In case of both other versions either isobutanol or benzyl alcohol is used in the highest concentration. The activation process was performed by a tooth bladed cowles dissolver at 16 m/s. The activation temperature was in all cases adjusted to 66°C for 25 minutes. A comparison of the rheological characteristics was done 24 hours after manufacturing. The data visualised in Figure 5 display the performance of both organic thixotropes in the systems equipped with described various solvent compositions with a special focus on the low shear viscosity. The small graph in the upper right corner displays the viscosity variations of the alcohol rich samples to the sample in the Xylene dominated system.

With both alcohol-rich systems, it is evident that the reference thickener loses significant viscosity at low shear rates. A different picture can be observed when utilising THIXATROL® PM 8058 in the same range of systems. Contrary to the market reference product, a viscosity rise in comparison to the reference product has been observed. This is the case when benzyl alcohol is dominant in the formulation. For systems dominated by isobutanol, the difference was slightly less than 10%. The viscoelastic characteristics of the tested coating, generated in a structure recovery test, are also underlining the benefits of THIXATROL® PM 8058. To simulate the post application behaviour systems, the structure of the coating was disrupted in a rotational measuring step by high shear rates of 1000 s-1. In a second, oscillatory step, the behaviour after the removal of initially applied shear, to analyse the properties of the coating after impacting the substrate. This is shown in Figure 6. If the displayed damping factor, also called the tan delta value, is above 1, then the fluid behaviour of the sample rules, and indicates that practically no structure is relevant to the system flows. If the damping factor acts below 1, the elastic behaviour of the sample is dominant and indicates the presence of an internal structure. A strong structure indicates excellent sag stability and should consequently correlate with the results generated in practice. However, in this testing also the time behavior plays a major role. The faster the structure recovers, indicated by the crossing a tan delta value of 1 coming from higher, the lower the time window for eventual sagging will be.

It can be seen that all samples display a dominance of the fluid character, indicated by tan delta values of above 1, directly after shear removal. In the case of the reference organic thixotrope, a pronounced influence of the solvent composition on the viscoelasticity can be observed. Directly after shear removal, both alcohols are shifting the characteristics strongly towards a further fluid dominated behaviour. With respect to the time scale, no redomination of the elasticity could be detected. The effects are strongest with a dominant concentration of Benzyl alcohol. The influence of the various alcohols on the sample with THIXATROL® PM 8058 is different. The absolute damping factors are only slightly differing in comparison to the reference sample in the standard, Xylene dominated system. The main difference is the point in time when tan delta is crossing the line of a value of 1. This structure recovery time is in both alcohol dominated systems are somewhat shorter. Consequently, these data are making potentially higher layer thicknesses after application of the coatings with THIXATROL® PM 8058 than with the reference rheology modifier expectable. To identify the optimum activation temperature window, the Xylene dominated system was chosen (Figure 7). In this study, individual samples were equipped either with THIXATROL® PM 8058 or a reference thickener activated at individual temperature.

It can be observed that THIXATROL® PM 8058 provides significantly higher viscosities at a shear rate of 0.1 s-1 than the reference product over the entire tested temperature ranges from 35°C to 75°C. Stable and predictable viscosity build with THIXATROL® PM 8058 can be obtained in a temperature range between 45°C and 75°C. The influence on the activation time at

Technical various temperature on viscosity build and sag control of THIXATROL® PM 8058 is shown in Figure 8.

The results are confirming the wide activation temperature window. Already with 30 minutes dispersing time at the lowest activation temperature of 35°C excellent viscosity build at low shear of 0.1s-1 could be detected. The most stable values have been obtained in a temperature range as of 45°C up to until 75°C could be repeated. In this range, an activation time of 30 minutes is sufficient for proper viscosities. An extension of the activation period to 45 minutes is generating a further slight increase of the performance. Also, in terms of stability after four weeks of storage at elevated temperature of 50°C, THIXATROL® PM 8058 provides excellent results. In Figure 9 it is shown that only when activated at 35°C noticeable changes of the viscosity or the sagging stability could be observed. As of an activation temperature of 45°C only slight variation of the viscosity could be detected. In the case of the sagging control no changes at all were seen.

Comparing the achievable maximum applicable layer thicknesses after application by airless spray in Figure 10, is showing that THIXATROL® PM 8058 is clearly outperforming the reference rheology modifier clearly.

The market reference organic thixotrope allows a maximum a layer thickness of 300 µm. THIXATROL® PM 8058 formulated at equal concentration and activation conditions guarantees sag control up to a range of 500-700µm. The investigation of various processing conditions has shown that the activation of THIXATROL® PM 8058 can successfully be performed by various methods (Figure 11). The best results at all were achieved when adding THIXATROL® PM 8058 to the grind process from the beginning of manufacturing, or alternatively, in a readily formulated, but unthickened coating system. In the last case, the applied shear can not be equally high as with the grind activation to avoid squirting out material from the vessel. In this case, a dissolver tip speed of 12m/s should be used. The relevant activation temperature needs to be controlled externally. In case of the direct addition, 16m/s or even higher tip speeds can be used. Also, no artificial temperature control needs to be done as the friction is high enough to generate the required energy.

Adding the organic thixotrope to the millbase has mostly performed in factory-based production. Post activation offers additional options, eg, a time efficient lab screening. Due to the low shear requirements of THIXATROL® PM 8058 for activation, it might also be possible to create pregels in certain solvents or solvent/resin blends that can then be used further in the coating process.

CONCLUSION As discussed, THIXATROL® PM 8058 extends the series of thixotropes with outstanding efficiency. THIXATROL® PM 8058 utilises the latest technology of highly sustainable diamide waxes being based on more than 75% renewable raw material. Thixatron® PM 8058 can withstand higher amounts of various alcohols and other highly polar solvents, and when compared to other amide based rheology modifiers, it exhibits superior viscosity and sagging stability. THIXATROL® PM 8058 provides a wide activation temperature window for very robust manufacturing under real life conditions. Additionally, when processed at low temperatures for limited periods of time, it is storage stable. Short activation periods of 30 minutes are providing viscosity stable coatings system. Also, the potential activation temperature starts from low levels. At 45°C a significant and stable viscosity build and excellent sagging stability was noticed. A further rise of the activation temperatures up to 75°C at equal dispersion period resulted in only small variations. In comparison to commercially available reference organic thixotropes, THIXATROL® PM 8058 acts significantly higher in efficiency. This allows the formulator to significantly reduce the loading level whilst keeping viscosity and sag control. Consequently, THIXATROL® PM 8058 is an ideal rheology modifier in the cost-effective and sustainable formulation of industrial, marine, and protective coatings as well as other nonaqueous systems.
