Rheology
YT-255C is a nonionic, hydrophobically-modified high-shear polyurethane leveling and thickening agent (HEUR). It imparts excellent flow, leveling, gloss development, film formation and high-shear viscosity to waterborne coatings. Tin-free and toluene-free, it is an eco-friendly rheology modifier suitable as a drop-in alternative to PS166. It performs well in waterborne coatings on plastic, metal, glass, wood and rubber, latex paints, industrial coatings, printing inks, adhesives and petrochemical water-treatment systems.
