Efka 4300 Acrylic block copolymer Efka Additives Dispersing agents >> Hyperdispersants Color pigment & dye >> Inorganic Pigment Color pigment & dye >> Organic Pigment Coatings >> Solventborne Automotive OEM Automotive refinishing methoxypropylacetate High molecular weight dispersing agent for deflocculation of all pigments in solvent based systems. Acrylic block copolymer. EFKA-4300 is a high molecular weight dispersing agent suitable for all pigments in solvent-based coatings. The high performance of EFKA-4300 in pigment dispersions gives the following advantages: • high colour strength • good stability against flooding, floating and flocculation • strong viscosity depressing effect EFKA-4300 is suitable for high quality solvent-based coating systems where the performance of difficult organic pigments is needed, like automotive OEM and refinish. Acrylic block copolymer. Shows good stability against flooding, floating and flocculation. Suitable for high quality solvent-based coating systems.
