COAPUR™ 520 W
Solvent-free liquid polyurethane thickener
Product overview
Coapur™ 520 W is a solvent-free and APEO-free HEUR thickener. It provides a very balanced rheology profile contributing to high-shear viscosities and medium-shear viscosities. As a consequence it provides a very good leveling in satin paints and improve significantly spattering resistance while offering also some antisettling properties. Furthermore, it provides very good response and efficiency in VAE binders. This new polyurethane thickener could therefore easily replace the use of a combination of high-shear and low-shear thickeners.
