Pigment Dispersant
CAS Number: 28212-44-4
Polymeric pigment dispersant with controlled anchor groups and polymer chains designed to provide high-affinity adsorption onto organic pigment surfaces and steric stabilization in both waterborne and solvent-borne systems. It significantly improves color development, tinctorial strength, and transparency of organic pigments, particularly phthalocyanines, quinacridones, and diketopyrrolopyrroles.
