COAPUR™ 4820
Solvent free liquid polyurethane thickener
Product overview
Coapur™ 4820 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™ 4820 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™ 4820 provides excellent coating properties due to its high associative effectiveness with every kind of binder.
Coapur™ 4820 increases specifically the viscosities at medium and high shear rates in order to improve tool load, film build, levelling and brush drag. Thanks to its exclusive rheological features, Coapur™ 4820 also prevents from settling and sagging tendency in low PVC formulations.
