DISPERBYK®-2008 - The Efficient Way to Matting High-Solids and Solvent-Free Coatings

Published on 2009-03-31. Author : SpecialChem

WESEL, Germany -- The matting of high-solids and UV coatings essentially depends on the perfect incorporation and dispersion of preferably high levels of silica-based matting agents. However, the use of these high levels of silica-based matting agents produces high viscosities, which in turn create production and application issues. On the other hand, the more perfect the orientation of matting agents in finished coating films, the higher the matting efficiency.

To solve this problem, BYK tailored a new additive based on CPT (Controlled Polymerization Technology) - DISPERBYK®-2008. Its pigment-affinic groups have been designed in such a way that they work equally well on surface-treated silicas and on untreated silicas. Special binder-compatible groups provide compatibility with many different polymers and monomers, and a special modification achieves excellent stabilization of both the finely dispersed silica particles and the inorganic fillers in the coating. The result is a powerful matting effect - so strong that it can even be achieved with standard matting agents and at low dosage levels. In addition, the significant reduction in viscosity provides easier processing properties for matt coatings made with DISPERBYK®-2008.
