FH-20815 is a high performance bio-based branched polyether/polyester polyol that is designed to be used in combination with isocyanates as a reactive component for 2-part polyurethane coatings and pigment pastes. FH-20815 is a universal polyol with low viscosity that imparts good chemical resistance with an elastic memory effect in the final coating.
Benefits
