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.

The present invention provides an adhesive composition for optical use, including a polyester-based urethane acrylate oligomer, an acrylate-based monomer, a photoinitiator, and a Anti-hydrolysis agnet, and an optical device equipped with an adhesive layer including photocured products of the adhesive composition for optical use.

A paint according to aspects of the present application has two components that form a solid material when mixed. A lack of Volatile Organic Compounds assist in distinguishing paint according to aspects of the present application from many existing paints. By controlling humidity in the spray (application) booth or in a separate curing booth, the time to cure the coating may be correspondingly controlled. That is, the higher the Relative Humidity, the faster the cure. When heat is introduced along with humidity, the time to cure the coating may be further controlled.
