Dispersing agent DCA-821

Introduction

DCA-821 is a high molecular weight dispersant containing alkaline groups, which improves pigment wetting, reduces the time required for the grinding process, and stabilizes pigment dispersion. It has a good wetting effect on inorganic fillers and carbon black with acidic surface, and can be used for dispersion and viscosity reduction of inorganic fillers and carbon black. This additive strongly reduces viscosity and improves the gloss and leveling of coatings, and has a particularly strong affinity for acidic groups on the surface of pigments.
