Dispex® AA 4140 is a derivative of a family of highly effective, low-viscosity dispersing agents for water-based coating systems, especially suitable for the dispersion of inorganic pigments and fillers. It is a solution of a sodium salt of an acrylic polymer in water and serves as an ideal dispersing agent for a wide range of water-based coatings. Offering improved storage stability for both pigment dispersion and formulated paint compared to inorganic dispersing agents, Dispex® AA 4140 exhibits little or no adverse reaction to high temperatures or pH changes.
