Product overview
Coapur™ 830 W is a solvent and Alkyl Phenol Ethoxylate (APE) free polyurethane thickener designed for all types of water based formulations, especially the solvent free formulations. Coapur™ 830 W 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. Coapur™ 830 W 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, build film, levelling and brush drag. Thanks to its exclusive rheological features, Coapur™ 830 W also prevents from settling and sagging tendency in low PVC formulations.
