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.

Claims

exact text as granted — not AI-modified
1 - 56 . (canceled) 
     
     
         57 . A composition comprising micronized chlorothalonil particles with a size of between 0.001 microns to 25 microns. 
     
     
         58 . The composition of  claim 57 , wherein the micronized particles have a size of between 0.001 to 10.0 microns. 
     
     
         59 . The composition of  claim 57 , wherein the micronized particles have a size of between 0.05 to 10.0 microns. 
     
     
         60 . The composition of  claim 57 , wherein the micronized particles have a size between 0.05 to 1.0 microns. 
     
     
         61 . The composition of  claim 57 , wherein the product is dispersed in wood. 
     
     
         62 . The composition of  claim 60 , wherein the product is dispersed in wood. 
     
     
         63 . The composition of  claim 57 , wherein the composition is an aqueous suspension. 
     
     
         64 . The composition of  claim 60 , wherein the composition is an aqueous suspension. 
     
     
         65 . The composition of  claim 63 , further comprising a dispersant. 
     
     
         66 . The composition of  claim 64 , further comprising a dispersant. 
     
     
         67 . The composition of  claim 63 , further comprising a stabilizer. 
     
     
         68 . The composition of  claim 64 , further comprising a stabilizer. 
     
     
         69 . The composition of  claim 63 , further comprising an emulsifying agent. 
     
     
         70 . The composition of  claim 64 , further comprising an emulsifying agent. 
     
     
         71 . The composition of  claim 63 , further comprising an enhancing agent. 
     
     
         72 . The composition of  claim 64 , further comprising an enhancing agent. 
     
     
         73 . The composition of  claim 57 , wherein the micronized chlorothalonil particle is milled. 
     
     
         74 . The composition of  claim 57 , further comprising a pigment. 
     
     
         75 . The composition of  claim 63 , further comprising one or more organic and/or inorganic biocides. 
     
     
         76 . The composition of  claim 64 , further comprising one or more organic and/or inorganic biocides. 
     
     
         77 . The composition of  claim 74 , further comprising one or more organic and/or inorganic biocides.
