Aquavis™ uls 255 NSAT is a nonionic, hydrophobically modified ethylene oxide urethane (HEUR) rheology modifier that offers excellent flow and leveling, uniform film formation and high thickening efficiency in water-based paints. It is designed to provide high thickening efficiency for Stormer (KU) viscosity build, enabling superior flow and leveling characteristics in the applied paint or coating. Aquaflow™ uls 255 has been shown to significantly reduce or eliminate latex agglomeration in paints containing vinyl-acrylic and vinyl acetate-ethylene latexes.
