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.
