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 biocide comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic biocide and an organic biocide, the inorganic biocide 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.
