Emission-free, hyperbranched wetting and dispersing additive for solvent-free epoxy systems and other reactive systems

News International-French

24 Dec 2012

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.


About BYK Additives & Instruments:
BYK Additives & Instruments is one of the world’s leading suppliers in the additives and instruments sector.

Approximately 87% of our sales are generated by foreign countries. Our major export markets are Europe, the United States, and the Far East.

Additives are chemical substances that are used in small quantities to improve product properties such as scratch resistance or surface gloss. Manufacturing processes are also optimized through the use of additives.


The coatings, printing inks, and plastics industries are some of the main areas of application of BYK additives. Yet in paper surface finishing, or the production of adhesives and sealants as well as construction chemistry, BYK additives are also improving the product properties and production processes. In 2009 BYK extended its portfolio with raw materials for the production of mold release agents for aluminum die casting.


BYK Instruments can quantify the quality of color and gloss and the physical properties of paint, plastic and paper products. Instruments from BYK are predominantly used for quality control.


BYK Additives & Instruments is a member of ALTANA, Wesel. ALTANA develops and produces high-quality, innovative products in the sector of specialty chemicals.

BYK Additives & Instruments employs around 1,400 people worldwide, 25% of whom work in research and development departments or technical laboratories.
