Additive for matting high-solids and solvent-free coatings
By Coatings Staff | April 06, 2009
BYK has introduced DISPERBYK-2008 to help solve the problem of achieving matting of high solids and solvent-free (such as UV) coatings. The additive is based on controlled polymerization technology (CPT). According to the company, the product’s pigment affinic groups have been designed is 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 is designed to achieve excellent stabilization of the finely dispersed silica particles and the inorganic fillers in the coating. The reduction in viscosity provides easier processing properties for matt coatings, says BYK.
