Coapur™ XS 71

Arkema Rheology & Specialty Additives

Coapur™ XS 71 is a solvent-free polyurethane thickener recommended for water-based systems, which should combine high viscosity with excellent pigment compatibility, for further use on a tinting machine or manual coloration. Coapur™ XS 71 offers a unique pseudoplastic rheology profile, performing strongly at medium shear rates and significantly at high shear rates. Its use ensures a smooth structure and an optimized ease of coat with no spatter. Coapur™ XS 71 ensures the best color development possible while using pigment pastes, even in the presence of problematic binders. The use of Coapur™ XS 71 limits viscosity drop after pigment paste addition, eliminates pigment flooding and floating during storage, and enables matching excellent results based on the rub-out test.
