    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: 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.

    Abstract: Disclosed herein are compositions and methods for treating wood to give it a desirable color that is durable over time, while at the same time rendering the wood resistant to fungal decay and insect attack. The wood may be pressure treated in a two-step process whereby the wood is first treated with a wood preservation composition, and then treated with a composition comprising pigments, or vice versa. Alternatively, the wood may be simultaneously treated with a composition comprising a wood preservative and a composition comprising pigments.
