DISPERBYK-163

DISPERBYK 163 is a high molecular weight block copolymer wetting and dispersing additive that stabilizes pigments of all types for solvent-borne coatings and pigment concentrates. DISPERBYK 163 deflocculates pigments and stabilizes them through steric hindrance, providing equal electrical charge to pigment particles. This results in repulsion and steric stabilization that prevents co-flocculation, reducing issues like flood and float-free color in pigment mixtures. The deflocculating properties of DISPERBYK 163 increase gloss, color strength, transparency, and hiding power while reducing viscosity of the millbase. For the advanced materials industry, DISPERBYK 163 delivers benefits like enhanced material performance, color consistency, optical properties and process efficiency during manufacturing through better pigment stabilization and dispersion.
