Rheology
YT-255B is a nonionic, solvent-free, hydrophobically-modified polyurethane leveling modifier (HEUR). It imparts excellent flow, leveling, gloss development and medium-shear viscosity to waterborne coatings. Tin-free and toluene-free, it is an eco-friendly rheology modifier suitable as a drop-in alternative to 8W for coatings and printing inks. 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.
