Efka® FA 4609 shows outstanding performance in dispersing and stabilizing inorganic pigments in particular titanium dioxide. In combination with a universal solvent based grinding resin like Laropal® A 81, low mill base viscosities with reduced pseudo plastic flow behavior can be achieved. Furthermore, Efka® FA 4609 is highly suitable to disperse iron oxide pigments.
Efka® FA 4609 is suitable for many coating systems such as:
