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: The present invention is directed to amine soluble, or solid copper triazole based wood preservative formulations containing certain types of quaternary ammonium compounds, or nonionic sufactants, and the use of these quaternary ammonium compound-, or nonionic surfactant-containing formulations to pressure treat and preserve wood. The addition of the quaternary ammonium compounds, or nonionic surfactants to the wood preservation treatment solutions allows improved penetration of the copper from the solution into wood and reduces the duration of time required to effectively pressure treat the wood with the preservation composition.

Abstract: A method for treating a wood substrate is provided. The method comprises contacting the wood substrate in a field application with an aqueous composition. The contacting is performed at a pressure of less than 20 psia. The aqueous composition comprises, by total weight of the aqueous composition, 1.0% to 10.0% by weight of a micronized basic copper carbonate, 0.35% to 2.5% by weight of a quaternary ammonium compound, and at least 80% by weight of water.
