  • Wood treatment for dimensional stabilization
    Patent number: 10442110
    Abstract: A process is provided for treating wood products including lumber, plywood and other engineered wood products comprising the steps of contacting a composition comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, with the wood product. The invention also provides wood products comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, that have greater dimensional stability compared to an untreated wood product.

  • Compositions and methods for wood preservation
    Publication number: 20070021385
    Abstract: Provided is a composition and method for the preservation of wood. The composition comprises 1) an azole and/or quaternary ammonium compound component and 2) a pyrethroid compound component such that wood treated with the composition has a greater decay resistance than wood treated to the same azole retention with the azole alone. The method comprises the application of the composition to wood.
