Abstract
The invention is a wood composite including wood particles, a binder, at least one wood stabilizer, and optionally other ingredients. Examples of the wood stabilizer are an ammoniacal wood stabilizer or ammoniacal copper dimethyl glyoxime. The wood stabilizer is present in an amount effective to reduce the swelling value of the wood composite to less than that of an analogous wood composite not treated with the wood stabilizer. A method for making wood composites and the product of that method are also disclosed. The method includes providing green wood particles and applying to them a wood stabilizer as described above, preferably without an intervening drying step. It is contemplated that the wood stabilizer can be applied in an amount effective to at least substantially preserve the resulting wood composite against at least one of rot, termites, and carpenter ants. While or after applying the stabilizer, a water repellant material is applied to the wood particles. The treated wood particles are then formed into a wood composite.
