Ink Dispersant
CAS Number: 68002-97-1
A high-performance polymeric dispersant engineered for pigment stabilization in solvent-based and UV-curable ink systems. It adsorbs strongly onto pigment surfaces to provide steric and electrosteric repulsion, preventing flocculation and sedimentation. The result is superior color strength, transparency, and gloss in finished ink formulations.
