Solsperse 22000 is a polymeric dispersant additive widely used in coatings, inks, pigments, and plastics industries. It improves pigment wetting, dispersion stability, color strength, and reduces viscosity in high-performance pigment systems. It is especially suitable for organic pigments, carbon black, and difficult-to-disperse inorganic pigments in solvent-based coatings, printing inks, and industrial formulations.
