DISPERBYK-2163

Wetting and dispersing additive for solvent-borne coatings and pigment concentrates. The additive deflocculates pigments and stabilises them by means of steric hindrance. It provides equal electrical charge to the pigment particles. The resulting repulsion and the steric stabilisation prevent a possible co-flocculation, which leads to flood and float-free colour in pigment mixtures. The deflocculating properties of the additive increase gloss, colour strength, transparency, and hiding power and reduce the viscosity of the millbase. The additive is recommended as a substitute for DISPERBYK-163 in all applications, especially for solvent-borne coatings and pigment concentrates.
