EFKA FA 4609
EFKA FA 4609
EFKA® FA 4609 is a polymeric wetting and dispersing agent with acidic groups. It shows outstanding performance in dispersing and stabilizing inorganic pigments in particular titanium dioxide. In combination with a universal solvent based grinding resin, low mill base viscosities with reduced pseudoplastic flow behaviour can be achieved. Furthermore, EFKA FA 4609 is highly suitable to disperse iron oxide pigments.
