DISPERBYK® is a wetting and dispersing additive for solvent-borne and aqueous systems. It is a solution of an alkylolammonium salt of a lower molecular weight polycarboxylic acid polymer. This product is suitable for both aqueous and solvent-borne systems. When added to the millbase of a white paint, it improves color acceptance and color development. In solvent-based and aqueous coatings DISPERBYK® prevents hard sedimentation. Furthermore, DISPERBYK® improves the effectiveness of pyrogenic silica. The water content may cause problems in epoxy and polyurethane systems.
