Polyurethane Thickener (HEUR)
CAS Number: 160617-49-2
Hydrophobically modified ethylene-oxide-urethane (HEUR) associative thickener that provides Newtonian to slightly pseudoplastic rheology in waterborne coatings, improving spatter resistance and leveling. It builds high ICI (mid-shear) viscosity for excellent roller and brush application. Compatible with a broad range of waterborne resin types.
