FH-20750 is a high performance bio-based polyol that is designed to be used in combination with isocyanates as a reactive component for 2-part polyurethane coatings and casting materials. FH-20750 is suitable for UV-stable and weather-resistant coatings, and shows particular water repellency, which results in less sensitivity to moisture while curing.

Application
In combination with Polymer MDI FH-20750 can be used for the production of 2 pack coating and casting materials. In combination with an aliphatic, HDI-based polyisocyanate, FH-20750 is suitable for the production of UV-stable and weathering resistant coatings.
In addition, FH-20750 is strongly water repellent, which results in less sensitivity to moisture while curing.
