Product overview
Coapur™ 2740 is a solvent and Alkyl Phenol Ethoxylate (APE) free associative polyurethane thickener designed for water based formulations. Coapur™ 2740 can be used sole or in combination either with other polyurethane thickeners or with any type of rheology modifiers such as acrylic or cellulosic thickeners, acting at low shear rates. Coapur™ 2740 is a pure associative thickener. It is designed to interact strongly with the binder of the formulation, in order to control the rheology at high shear rates. Coapur™ 2740 helps to match the highest coating quality possible for water-based formulations.
