The adhesive includes, as a primary ingredient thereof, a polymer containing one or more monomers which would when polymerized, or copolymerized yields a Shore D hardness greater than the Shore D hardness of the wood substrate. Monomers of this type include styrene, methyl methacrylate, vinyl acetate, vinyl chloride and diphenylmethane diisocyanate. The adhesive may also contain a tackifying resin, a flexibilizing polymer, a plasticizer, a filler, and other conditioning additives. |
