Dispersant
CAS Number: 9003-01-4
High-molecular-weight polyacrylic acid dispersant that provides electrostatic and steric stabilization of pigment and filler particles in waterborne coating and ink formulations. It enables high pigment loading, lowers viscosity of pigment pastes, and prevents flocculation and color float. Suitable for use with inorganic pigments such as TiO₂, iron oxides, and carbon black.
