Coapur™ XS 83

Coapur™ XS 83 by Coatex (Arkema Group) is a solvent-, APEO- and tin-free polyurethane thickener. Coapur™ XS 83 provides a unique pseudoplastic rheology profile with a strong shear-thinning behavior. Its use ensures good gloss development, good sprayability, smooth structure and an optimized ease of application by spray, roller or brush. Coapur™ XS 83 thickener is recommended for water-based systems and is suitable for industrial and decorative applications requiring high film thicknesses and excellent sag, water, stain and corrosion resistance. This polyurethane thickener contributes to improved color strength and reduce rub-out issues when using pigment pastes, even in presence of problematic binders. It displays high storage modulus with improved suspension power. Provides unique elastic character leading to long term & overnight storage stability and anti-settling property. Offers no detrimental effect on adhesion or visual properties. The use of Coapur™ XS 83 also limits viscosity drop after pigment paste addition, pigment flooding and floating during storage. Recommended dosage levels are 0.1-0.8 % when used alone in decorative paints, 0.1-1.0 % in industrial coatings, 0.05%-0.8 % when used in combination with a medium and/ or high shear effective thickener in all kinds of formulations.
