Cognis at Chinacoat 2010: high-performance solutions for successful green coatings

(PresseBox) (Monheim, ) Sustainability and performance are key drivers of today's paints and coatings market. At this year's Chinacoat, global specialty chemicals supplier Cognis exhibited a variety of market-ready products for the Asian paints and coatings industry that are aligned with these demands. These included a performance enhancing natural oil-based coalescent, a multifunctional dispersing and wetting agent, and highly efficient rheology modifiers. Also presented at the company's booth were a range of innovative defoamers with outstanding performance, and a new generation of renewable non-ionic surfactants.

The green trend is starting to become a part of mainstream society in Asia, driven by greater awareness of environmental issues on the one hand and stricter regulatory requirements on the other. With its Greenovating concept, Cognis Functional Products focuses on developing genuinely green chemical solutions with quantifiable benefits. These products enable manufacturers to make verifiable marketing claims that help them to achieve success in the paints and coatings market.

State-of-the-art coating additives

At the show, Cognis featured Loxanol EFC 300, a highly efficient, VOC-free, natural oil-based coalescent that offers excellent efficiency in reducing the minimum film-forming temperature. It also provides higher pendulum hardness, which means improved dirt pick-up resistance compared to petrochemical-based benchmarks.

Another Cognis product on display was Hydropalat 216, an APEO-free wetting and dispersing agent suitable for organic and inorganic pigment concentrates, tint bases and factory-finished paints. It is a more efficient, low-foaming alternative to inflexible polymeric and alkyl-blocked APEO-based universal wetting and dispersing aids.

Also presented at the show was a range of highly efficient rheology modifiers, based on state-of-the-art associative thickening technology for water-based paints and coatings. These offer a wide variety of rheological profiles, and contain no VOCs, APEOs, heavy metals or solvents. They included:

- DSX 3291, a low-shear rheology modifier which is up to five times more efficient than the benchmark. It offers easy handling, easy incorporation without high shear mixing, and excellent sag resistance in thick coatings.
- DSX 3121 is a Newtonian high-shear (ICI) viscosity builder that exceeds HEUR technology in both performance and efficiency. It offers improved syneresis resistance and is ideal for one-coat coverage. It is one of the latest additions to Cognis' range of rheology modifiers.

In addition, a number of innovative defoamers offering excellent defoaming performance and efficiency were showcased at the Cognis booth. These products are specifically designed for paints across the full PVC range and for tinting systems. On show were:

- Dehydran SE 2, a high performance, VOC-free, silicone-polymer emulsion defoamer for paints over the whole PVC range that offers an optimum balance of compatibility and defoaming efficiency. Dehydran SE 2 can be added at either the grind or the let-down stage of manufacture.
- FoamStar A 10, A 12, enhanced mineral oil hyperbranched-polymer-based defoamers that provide very fast bubble-break times for mid to high-PVC paints.
- FoamStar A 34, A 36, A 38, based on hyperbranched high-end organo-silicone polymers that deliver fast defoaming action and very high efficiency in resin-rich and surfactant-rich, mid to low-PVC paints and tinting pastes.
- FoamStar A 46, a trouble-shooting defoamer that gives an excellent film appearance and is up to 50 percent more efficient than benchmark silicone defoamers. It is an excellent choice for use in hard-to-defoam systems and where microfoam trapping is a problem.

Finally, Cognis introduced the new Disponil NG series of next-generation, gel-free, low-foaming, low-pour-point, non-ionic surfactants for emulsion polymerization. These properties result in easier handling and reduced energy consumption during latex production compared to traditional surfactants. Emulsion production times are reduced, and transport and storage can be carried out at lower temperatures, without the need for additional heating. The new Disponil NG products are suitable for use in all types of latices, as either in-process or post-stabilization surfactants.

"In the Asia-Pacific region, the green trend is increasingly becoming a major driving force," comments Shailesh Shah, Director Global Marketing Coatings. "If manufacturers want to succeed in their markets, they need to be able to develop products that satisfy consumer demands while also complying with new regulations. With our expertise in additives for water-based architectural and industrial paints and coatings, we are well placed to help manufacturers leverage the green trend and gain a competitive edge in their markets."
