Weatherproof aqueous wood coatings
An aqueous based coating composition comprising a fatty amine quaternary having the structure of formula (I): R.sup.1R.sup.2R.sup.3R.sup.4N.sup.+X.sup. wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from saturated or unsaturated, linear or branched, substituted or unsubstituted alkyl, aralkyl, or alkenyl groups comprising from 1 to 30 carbon atoms, whereby at least one of R.sup.1, R.sup.2, R.sup.3, and R.sup.4 is a C12-C30 group, and X.sup. is an anion from an inorganic or organic acid, is provided. The fatty amine quaternary may contain ethoxy and/or propoxy groups. One or more of R.sup.1, R.sup.2, R.sup.3, and R.sup.4 may be substituted and contain one or more hydroxyl substituents or ether linkages. Methods for imparting water resistance to a wood substrate having up to 100% moisture by applying a coating composition having the fatty amine quaternary of formula (I), and for preparing an aqueous coating composition comprising the fatty amine quaternary of formula (I) are provided. Also provided is a coated water resistant wood substrate comprising the fatty amine quaternary of formula (I).

WOOD TREATMENT FOR DIMENSIONAL STABILIZATION
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.
