Dispersions, Resins and Additives
Efka® PA 4400
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, reduces flooding problems, and provides 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 significant higher molecular weight compared with the Efka polyurethane-based polymeric dispersants. This gives better deflocculation of organic pigments.
