Polyurethane thickener  RJ-665
Introduction：
Thixotropic polyurethane thickener RJ - 665 is a kind of nonionic, low solvent, hydrophobic modified polyurethane association thickener, can effectively improve middle and low shear viscosity, have a good thickening effect, high thixotropic performance and high yield value.
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.
Can be used to formulate coatings has the stereoscopic pattern effect, and the T - 901 used under low dosage can effectively improve the low shear viscosity, the coating has high pseudoplastic.
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.
