CX 4340 is a highly effective- low viscosity dispersing agent for water-borne coating systems. It is especially suited for the dispersion of inorganic pigments. This straw colored liquid is a solution of a sodium salt of an acrylic copolymer in water. The copolymer is manufactured to a relatively narrow molecular weight distribution thus resulting in a consistent product quality with maximum effectiveness. The special copolymer backbone is designed for complete compatibility with polypropylene and hexylene glycols used in high proportions in water-borne high gloss coatings to promote wet edge time. It is more hydrophobic than DISPEX AA 4140.
