Efka 4020 Modified polyurethane Efka Additives Color pigment & dye >> Inorganic Pigment Color pigment & dye >> Organic Pigment Dispersing agents >> Hyperdispersants Epoxy Resins Coatings >> Solventborne Architectural / Decorative General Industrial /Maintenance Pigment concentrates methoxypropylacetate Modified polyurethane dispersant for the deflocculation of inorganic pigments, carbon blacks and many organic pigments for aromatic-free systems with low odour. EFKA-4020 is a polymeric dispersant principally developed for stabilizing inorganic pigments including carbon blacks. It also has an excellent performance in many organic pigments. This results in: • reduced grinding time • improved gloss • prevention of flooding and floating problems • higher colour strength Due to its particularly good combination of price and performance, and high solid content EFKA-4020 is a very attractive substitute for conventional wetting and dispersing agents. It is possible to mix combinations of inorganic pigments stabilized with EFKA-4020 and organic pigments stabilized with other EFKA high molecular weight polymeric dispersants. EFKA-4020 has been especially developed as a general dispersing agent for all low aromatic or aromatic-free solvent-based paints from high performance industrial coatings to normal decorative paints. It gives excellent performance in epoxy systems as well. EFKA-4020 can also be used in universal solvent-based pigment concentrates. Modified polyurethane. Stabilizes inorganic pigments and shows excellent performance in many organic pigments. Used as general dispersing agent for all low aromatic or aromatic-free solvent-based paints.
