Furfuryl alcohol and lignin adhesive composition

The present disclosure relates to a novel and economical process for preparing bonded wooden substrates using an adhesive formulation based on a by-product obtained from a chemical pulping process. The adhesive formulation, which is novel and also forms part of the present invention, contains two parts, a reactive component and a catalyst component. When the two parts are mixed together and heated under pressure, they produce a strong, persistent bond. A wood adhesive formulation containing furfuryl alcohol, lignin, maleic anhydride, and iron and zinc catalysts.
