Abstract: 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.

Abstract: An adhesive may be formulated with a functional component that reacts in the presence of ultraviolet light with a neighboring functional component to form a nonreversible bond therebetween. The functional component may include at least one —C═C— functional group that is able to undergo dimerization with a neighboring component. A method for making the adhesive includes covalently bonding the functional component to a support polymer, wherein the functional component may be covalently bonded to the support polymer by a linking molecule. A kit containing the adhesive and an ultraviolet light source is also provided.
