BYK Introduces DISPERBYK®-2152, a Hyperbranched Wetting & Dispersing Additive

Published on 2012-12-21. Author : SpecialChem

In order to obtain excellent pigment deflocculation and stabilization, an additive with highly effective pigment-affinic groups is required. These pigment-affinic groups are mostly aminic and able to react with epoxy resins. The ideal solution would be an additive with encapsulated aminic pigment-affinic groups. However, creating such an additive was not possible using existing technologies.

In 2011, BYK Additives & Instruments have developed DISPERBYK®-2151, an innovative additive which combines high effectivity with stability.

Now, BYK Additives & Instruments takes it to the next level with the new DISPERBYK®-2152 which is a 100% additive based on the same active substance. Thus, the mechanism of DISPERBYK®-2152 is analogous to that of DISPERBYK®-2151. The additive contains no solvents or volatile components and fulfills the strict requirements of the German AgBB as well as French VOC standards.

DISPERBYK®-2152 is recommended for use in industrial, wood and furniture, protective, and automotive coatings, as well as for ambient curing systems and adhesives.
