Abstract: Wood preservative compositions comprising a particulate copper compound in a solvent carrier with low aromatic content. Particulate copper dispersions in this composition demonstrated superior stability, and wood treated with the composition is protected from attack by wood decay fungi and termites. The invention is also directed to wood preservative compositions comprising: (a.) a biodegradable organic solvent carrier selected from the group consisting of vegetable oil, renewable resource oil, and biodiesel; (b.) a dispersion of solid particles of a metal compound having a particle size between about 0.005 microns to about 10 microns; (c.) an organic biocide; and (d.) a dispersant; ratio of the dispersant to the metal compound is from about 1:500 to about 100:1 (wt/wt). The invention is also directed to compositions comprising penflufen and solvent carriers. The invention is also directed to methods of treating wood using the compositions, and wood treated with the disclosed compositions and methods.

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.
