Efka 4340 Acrylic block copolymer Efka Additives Dispersing agents >> Hyperdispersants Color pigment & dye >> Organic Pigment Coatings >> Solventborne Automotive OEM >> Top coats >> Basecoat Automotive refinishing methoxypropanol High molecular weight dispersing agent for deflocculation of organic pigments in solvent based systems. Acrylic block copolymer. EFKA-4340 is a high molecular weight dispersing agent designed for use in solvent-based high-end performance coatings systems like automotive OEM and Refinish. EFKA-4340 has improved pigment affinity for organic pigments, especially where high transparency is required. EFKA-4340: • improves colour development with organic pigments • improves transparency • improves viscosity reduction at high concentration of pigments in the grinding stage • has excellent compatibility with CAB containing base-coat systems • gives excellent glossEFKA-4340 is specially designed for use in solvent-based high-end performance coatings systems, such as automotive OEM and refinish. It is also highly suitable for CAB base-coats and all topcoats. Acrylic block copolymer. Improves viscosity reduction at high concentration of pigments in the grinding stage. Used in solvent-based high-end performance coatings systems.
