FH-20818 is a high performance bio-based fatty chemistry polyester polyol that is designed to be used in combination with isocyanates as a reactive component for 2-part polyurethane coatings. FH-20818 is a universal polyol with low viscosity that imparts good self leveling and bonding properties while producing excellent flexibility in the final coating even at low temperatures.

Application
In combination with Polymer MDI FH-20818 can be used to produce 2-pack coating and casting materials. Due to the hydrophobic properties and its low viscosity, this material is therefore eminently suitable for electro potting compounds.
In addition, FH-20818 is strongly water repellent, which results in less sensitivity to moisture while curing.
