A cardanol modified epoxy polyol may be used for forming a polyurethane resin system for use in applications such as coatings and composites formed by filament winding. The polyurethane resin system includes an isocyanate-reactive component that has a first cardanol component and the cardanol-modified epoxy polyol, and includes an isocyanate component that includes at least one polyisocyanate. The cardanol-modified epoxy polyol is a reaction product of an epoxy component and an epoxy-reactive component at a ratio of epoxy groups to epoxy reactive groups from 1:0.95 to 1:5, and the epoxy-reactive component includes a second cardanol component.
A polyurethane resin system, comprising:
The polyurethane resin system as claimed in claim 5, wherein the at least one other polyol includes at least one selected from the group of a low molecular weight polyol having a number average molecular weight less than 500, a high hydroxyl number polyol having an average hydroxyl number from 260 to 800 mg KOH/g, and a natural oil derived polyol.
