Abstract: Methods for spraying a coating composition, with or without a fire retardant, onto a wood product, and wood products produced by the methods are disclosed. The method comprises a two-component system comprising (i) one or more aliphatic isocyanate compounds; and (ii) one or more aliphatic amine compounds, and, optionally, one or more fire retardants which are stored separately and combined in a spray gun to form a mixture which is then sprayed onto the wood product to form an external coating on one or more surfaces of the wood product. Wood coated with the compositions disclosed herein have increased dimensional stability and are resistant to checking and/or splitting compared to untreated wood.

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.

Abstract: The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.
