Coapur™ 520 W

Arkema Rheology & Specialty Additives

Coapur™ 520 W is a solvent-free and APEO-free HEUR thickener. It provides a very balanced rheology profile, contributing to both high-shear and medium-shear viscosities. As a consequence, it provides very good leveling in satin paints and improves spattering resistance significantly, while also offering some anti-settling 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.
