COAPUR™ 817 BB
Coapur™ 817 BB is a 93% bio-based HEUR thickener. Coapur™ 817 BB is a solvent-free and APEO free pure associative polyurethane thickener (also called HEUR, NISAT or NSAT). It can be used sole or in combination with other polyurethane thickeners or with other types of rheology modifiers such as acrylic or cellulosic thickeners. It increases specifically viscosities at medium and high shear rates in order to improve tool load, film build, leveling and brush drag.
