Solvent-free liquid polyurethane thickener
Contact our experts
Product overview
Coapur™ 975 W offers an unique pseudo plastic rheology profile, performing strongly at medium shear rates while contributing significantly at high shear rates. It builds low shear viscosity reasonably high in order to help optimize both levelling and sag resistance. Coapur™ 975 W is a solvent, Alky Phenol Ethoxylates (APEO), tin and heavy metal free associative polyrethane thickener and opens new perspectives particularly for low emission water based paints needing attractive in can apperance and tool load, outstanding coatings properties and colour acceptance. Coapur™ 975 W is easy to use and suitable for automatic dosing systems thanks to its low viscosity. Coapur™ 975 W is designed to be used sole or in combinaison ideally with high shear viscosity builders such as Coapur™ 2025 if brush drag, film build or spatter resistance have to be increased specifically
