Polyurethane thickener  RJ-650
Introduction：
Polyurethane efficient thickener RJ - 650 is a kind of nonionic, low solvent, hydrophobic modified polyurethane association thickener, can effectively improve the medium and high shear viscosity, and have higher thickening rate. And cellulose thickener and alkali swelling type thickening agent has excellent formula compatibility, can make the paint designer the freedom to choose collocation of cellulose thickener and alkali swelling thickening agent.
This product is designed for preparation of latex paint, and thickener or thickener T - 905 T - 901 used under low dosage can effectively improve the shear viscosity, including make coating has high thickening effect and rheological properties.
Recommended for a variety of emulsion system, can also be used in industrial paint, textile sizing agent, adhesive, printing ink, leather and other water system.
