Coapur™ XS 83

Arkema Rheology & Specialty Additives

Coapur™ XS 83 is a solvent-free polyurethane thickener recommended for use in water-based systems, which should combine high in-can viscosities with excellent pigment compatibility, suitable for tinting machines, manual coloration, industrial, and architectural coatings.Coapur™ XS 83 provides a unique pseudoplastic rheology profile with a strong shear-tinning behavior. Its use ensures a smooth structure and an optimized ease of application by spray, roller, or brush. The highly pseudoplastic rheology profile, combined with a fast recovery of the viscosity following the application makes the Coapur™ XS 83 suitable for industrial and decorative applications requiring high film thicknesses and excellent sag resistance. Coapur™ XS 83 contributes to improving color strength and reducing rub-out issues when using pigment pastes, even in the presence of problematic binders. The use of Coapur™ XS 83 also limits viscosity drop after pigment paste addition, pigment flooding, and floating during storage.
