Hyperdispersant for Carbon Black & Organic Pigment Inks
Polymeric hyperdispersant with anchoring groups and solvated polymer chains, designed to stabilize carbon black and organic pigment dispersions in solvent-based, UV-curable, and waterborne printing inks. Analogous in performance to BYK-163 and Solsperse 32000, this dispersant achieves maximum pigment loading with minimum viscosity, eliminates flocculation, and delivers superior color strength, gloss, and transparency in finished inks.
