Dispersing agent specifically used in coil coating applications and polyester / melamine stoving enamels. EFKA PA 4400 is a modified polyurethane for stabilizing inorganic and organic pigments with strong viscosity depressing properties. It improves gloss- reductions of flooding problems- higher color strength and lower viscosity. This product is used in all kinds of solvent borne coatings. EFKA PA 4400 is an acrylic polymer with significat higher molecular weight compared with the EFKA polyurethane-based polymeric dispersants. This gives better deflocculation of organic pigments.
