Abstract
Provided is a sprayable polyurethane coating, comprising the reaction product of an isocyanate component and an isocyanate-reactive component, wherein the isocyanate component includes an isocyanate, and the isocyanate-reactive component includes a cardanol-modified epoxy polyol. 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 cardanol component. A sprayable polyurethane based reaction system comprising the sprayable polyurethane coating and a process for forming the sprayable polyurethane coating are also provided.
