A reaction system for forming polyurethane elastomers includes a cardanol modified epoxy polyol. In particular, the reaction system has an isocyanate-reactive component that includes the cardanol-modified epoxy polyol and 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 1:1 to 1:5, and the epoxy-reactive component includes a cashew nutshell liquid having a cardanol content of at least 85 wt %, based on a total weight of the cashew nutshell liquid.

The present disclosure provides an adhesive composition comprising derivatives of native lignin and an isocyanate-based binder such as methylene diphenyl diisocyanate. The present compositions may further comprise formaldehyde-based resins such as PF, UF, and MF. While not wishing to be bound by theory, it is believed that incorporating derivatives of native lignin in isocyanate compositions will reduce incidence of pre-curing.

The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.
