ABSTRACT:
A wood enhancement agent treated engineered wood product. The wood enhancement agent typically includes at least one of a preservative, a water repellant, a fungicide, an insecticide, a stabilizing agent, wax, an ultra-violet light inhibitor, and combinations thereof, and may also include an antioxidant. The wood enhancement agent is incorporated into the engineered wood product during a billet making process or after forming the billet. The wood enhancement agent may be applied simultaneously with a bonding agent or at a later time, for example applied to a scrim log mat during a pre-press process or inside a steam press chamber. Alternatively, the wood enhancement agent may be applied to a warm billet after steam press, or to a reheated billet, by dipping, spraying, or flood coating the billet, or by diffusion, vacuum impregnation, pressure, or a combination thereof.
