Reduced complexity in waterborne formulations: inherently matte acrylics and cationic functionality without compatibility issues

 
Using a proprietary process, Zschimmer & Schwarz offers an inherently matte acrylate polymer. After drying, a film with low gloss, high flexibility, excellent stability and, above all, excellent transparency is formed. The time- and labour-consuming incorporation of solid matting agents is eliminated, making the formulation much simpler, more stable and more economical. The IPN technology (interpenetrating polymer network) of Zschimmer & Schwarz involves two different ionic structures in the same polymer network at a neutral pH value. These polymers form cationic functionalities during drying, providing excellent tannin, stain and dye blocking without the compatibility problems common to cationic polymers. This talk outlines how these innovative polymer technologies benefit applications in graphic arts or wood coating, meeting the increasingly demanding requirements of modern coating formulations.
