EFKA^® FA 4600

Anti-settling agent for non-aqueous systems; provides good anti-settling properties in polar systems.

EFKA^® FA 4600 is an antisettling agent for non-aqueous paints. As a modern anti-settling agent, it acts via adsorption phenomena on the pigment surface and effectively prevents pigments from settling and forming hard, difficult-to-stir sediments even in low-viscosity coatings such as, e.g., dipping paints and wash-primers. This is possible even in the presence of specific high density pigments based on lead, chrome, barium, iron and titanium. In addition, the uniform electrostatic charge imparted by EFKA^® FA 4600 prevents re-agglomeration thereby counteracting any premature settling of the pigments. EFKA^® FA 4600 is an easy to use liquid anti-settling agent, the particular advantage of which is that it is effective over a broad range of polarity. It can, therefore, be used in a nitrocellulose lacquer, the solvents of which are mainly polar, as well as in decorative paints which only contain white spirit, i.e., a non-polar solvent. EFKA^® FA 4600 is also an excellent anti-settling agent for low-viscosity printing inks, e.g., flexographic and gravure. In particular it counteracts the tendency of inorganic pigments to settle.
