February 06, 2026
Dispersogen 145 is an anionic, surfactant-based dispersing agent for water-based and solvent-based pigment preparations, suitable for organic and inorganic pigments.
Dispersogen 145 is recommended for use in point-of-sales colorants in combination with a nonionic dispersing agent, e.g. Dispersogen MT 200.
The general dosage recommendation is 2-3% on organic pigments and 2-3% on inorganic pigments.
