Coapur™ 830 W by Coatex is a water soluble non-ionic polyurethane. It is a solvent and Alkyl Phenol Ethoxylate (APE) free polyurethane thickener designed for all types of water based formulations, especially the solvent free formulations. Can be used sole or in combination either with other polyurethane thickeners or with other types of rheology modifiers such as acrylic or cellulosic thickeners.
It provides excellent coating properties due to its high associative effectiveness with every kind of binder. COAPUR™ 830 W increases specifically the viscosities at medium and high shear rates in order to improve tool load, film build, levelling and brush drag. It also prevents from settling and sagging tendency in low PVC formulations. The incorporation of COAPUR™ 830 W, as sole thickener in semi-gloss and satin dispersion paints, improves storage stability and coating yield.
