Clariant unveils two innovative reactive emulsifiers for polymeric binders – Emulsogen® CPA 100 XS and Emulsogen CPN 100 XS – to help paint makers achieve architectural coatings offering outstanding water-resistance and greater resistance to dirt pick-up and snail trails.
Clariant’s new emulsifiers firmly "anchor” to pure acrylic or styrene acrylic binders to create stabilised, outstandingly hydrophobic, small-particle binders. They prevent emulsifier migration that would typically impair key attributes such as paint water resistance and substrate adhesion, or cause unsightly aesthetic defects like snail trails and dirt pick-up, boosting chances for coatings manufacturers to address latest requirements.
"Dirt pick-up and leaching resistance are increasingly demanded of today’s exterior architectural coatings. Although influenced by various factors, an acrylic or styrene acrylic binder that is less sensitive to water uptake will form a tightly-sealed film able to retain ingredients and protective qualities. Without emulsifier leaching to contribute adverse effects to the paint performance, there’s much less chance for unwanted snail trails etcetera to occur. In testing, our new anchored emulsifiers deliver whitening-free, clear films compared to alternatives, an industry-recognised sign of a higher quality, water-resistant binder to advance higher-performing paints and fewer defects,” comments Sebastian Prock, Global Marketing Segment Leader Industrial Applications at Clariant.
On top of paint benefits, Clariant’s new emuslifiers bring the advantages of a smoother, less disrupted binder production process. Because the binder has smaller, stabilised particles, there is less clogging or coagulation from large particles to cause slower stirring or a need for frequent cleaning breaks.
