Abstract
A method is provided for improving the bond strength and quality between a borate-treated wood material and a phenolic resin in a wood composite product, the method having the steps of bonding the wood material with an adhesive system comprising the resin and an additional base, the base providing a substantial increase in the alkalinity of the adhesive system over that provided by the resin, the increase sufficient to limit the bonding of borate molecules with the phenolic resin molecules to such an extent as to allow a substantially complete cross-linking of the phenolic resin molecules to occur. An adhesive system is also disclosed for use in the production of wood composite products.
