Efka 4330 Acrylic block copolymer Efka Additives Dispersing agents >> Hyperdispersants Color pigment & dye >> Inorganic Pigment Color pigment & dye >> Organic Pigment Coatings >> Solventborne methoxypropylacetate High molecular weight dispersing agent for deflocculation of all pigments in solvent based systems. Acrylic block copolymer. EFKA-4330 is a high molecular weight dispersing agent suitable for stabilising all pigments for solvent-based coatings. The high performance of EFKA-4330 in pigment dispersions gives the following advantages: • high colour strength • good stability against flooding, floating and flocculation • low viscosity of the mill base • high pigment loading EFKA-4330, due to the very wide compatibility in most current systems used in solvent-based coatings, is especially suitable for the production of resin minimal pigment concentrates in combination with a multi compatible dispersing resin, e.g. EFKA-1125 Acrylic block copolymer. Shows high color strength, low viscosity of mill base and high pigment loading. Used in solvent-based coatings, suitable for the production of resin minimal pigment concentrates.
