Cognis' Dehydran SE 2 - high-performance, VOC-free, ultra-low SVOC, silicone-polymer emulsion defoamer for premium water-based paints and clear coats

(PresseBox) ( Monheim, )
Global specialty chemicals supplier Cognis has launched Dehydran SE 2, a innovative defoamer that offers one of the best defoaming performances in paints with a volatile organic compound (VOC) content of between zero and 100 grams per liter. The defoamer itself is VOCfree (according to EU and US standards) and contains very low levels of semivolatile organic compounds (SVOCs), in line with the strictest emission standards. The defoamer emulsion is based on a combination of patented hyperbranched polymers and organomodified silicones, and is specifically designed for use in paints and coatings with proenvironmental labeling. Dehydran SE 2 enables paint manufacturers to serve consumers' demands for sustainable products while enhancing product performance.

The Dehydran defoamer range from Cognis offers marketleading defoaming performance, excellent longterm efficiency, and outstanding compatibility in a wide range of applications. Cognis is now enhancing its existing portfolio by launching Dehydran SE 2, a highperformance defoamer for premium waterbased paints and clear coats that is highly compatible, easy to handle and minimizes gloss reduction.

Optimum balance between compatibility and defoaming efficiency

Dehydran SE 2 offers excellent foam suppression and long term persistency in premium flat, midlow PVC paints and clear coats. Furthermore, it does not cause haze or fogging and minimizes gloss reduction.

A genuine green defoamer solution

The new defoamer fits with Cognis' innovative Greenovating strategy that was designed to help paint and coatings manufacturers to satisfy the consumer trend for products that are both sustainable and highperforming. It is free from VOCs (in line with the 2004/42/EC directive and the US-EPA 24) and it is one of the most efficient defoamers with ultralow semivolatile organic compound (SVOC) content. Moreover, Dehydran SE 2 helps paint manufacturers to formulate paints and clear coats which meet various environmental standards and safety certifications, such as the German TÜV, Green Seal GS-11, the EU Ecolabel or the Blue Angel environmental seal.

Paula Gómez Perea, Senior Marketing Manager Coatings Europe, comments: "Dehydran SE 2 is the latest addition to our range of defoamers and we expect it to be a real success: various tests, including air entrainment, bubble break times, storage stability and sponge roller application tests, carried out with several paint and coating systems have shown that Dehydran SE 2 offers the optimum balance between compatibility and defoaming persistency with minimized influence on gloss."
