FH-20780 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. FH-20780 is suitable for UV-stable and weather-resistant coatings, and shows particular water repellency, which results in less sensitivity to moisture while curing. A high Tg also imparts high hardness in the final coating.
