Byk -155 Sodium salt of an acrylate copolymer BYK Chemie Dispersing agents >> Surfactants-like >> Sodium polyacrylates / Polyacrylic acids Flow / Levelling agent >> Polyacrylate Coatings >> Waterborne Architectural / Decorative General Industrial /Maintenance Pigment concentrates Water Byk® 155 is a solution of a sodium salt of an acrylate copolymer. Dispersant for emulsion paints and aqueous systems to reduce the time required for the grinding process and to stabilize the pigment dispersion. It improves gloss and levelling. BYK®-155 does not stabilize foam and can be used as the sole dispersing additive in gloss and semi-gloss emulsion systems. In tinting systems, it achieves (in combination with a wetting additive such as Disperbyk®-181) good color acceptance. It is used in architectural paints, general industrial coatings and pigment concentrates. BYK®-155 is stable over a pH-range of 4-10. BYK®-155 is only available on the North American market. Solution of a sodium salt of an acrylate copolymer. Used in architectural paints, general industrial coatings and pigment concentrates. Offers improved gloss and levelling.
