Description:
Coapur™ 830 W is a solvent and Alkyl Phenol Ethoxylate (APE) free polyurethane thickener suitable for all types of water-based formulations, especially solvent-free ones. It can be used alone or in combination with other polyurethane thickeners or with other types of rheology modifiers like acrylic or cellulosic thickeners. It offers excellent coating properties due to its high associative effectiveness with various binders. It specifically increases viscosities at medium and high shear rates to enhance tool load, film build, leveling, and brush drag. Additionally, it prevents settling and sagging tendencies in low PVC formulations.
