Wetting and dispersing additive for solvent-based and solvent-free coatings to improve pigment wetting, reduce the time required for the grinding process and stabilize the pigment dispersion. Deflocculation of the pigments stabilizes hue and color strength and prevents flooding/floating. The additive strongly reduces viscosity and improves gloss and levelling of the coatings. BYK®-220 S is able to stabilize all pigments and is preferably used in industrial paints. It increases gloss, prevents flooding/floating and reduces millbase viscosity. BYK®-220 S is distinguished by a broad compatibility in two-pack acrylic systems. It is used in industrial, architectural, automotive, wood and furniture coatings.
