  • Patent number: 10829648
    Abstract: A composition containing succinate dehydrogenase inhibitor and a potentiator has been discovered to enhance the activity of the succinate dehydrogenase such that the amount of the succinate dehydrogenase inhibitor need to effectively treat a microbial substance can be reduced substantially. The compositions may be used as additives for paints and coatings, and protecting crops, seeds, wallboard, metal working fluids, wood from mold, fungi and other microbes.

  • Patent number: 8911792
    Abstract: Disclosed herein is a composition concentrate that is suitable for treating wood upon dilution with water in a weight ratio of concentrate to water of between 1:10 and 1:100. The concentrate contains copper ammonium cations, zinc ammonium cations, arsenate and/or hydrogen arsenate anions; carbonate and/or bicarbonate anions, ammonia and water, wherein the total amount of copper and zinc is from 17% to about 22% by weight based on the total volume of the concentrate. Also disclosed is a process for producing ammoniacal copper zinc arsenate concentrate.

  • Patent number: 8414931
    Abstract: Disclosed is a wood preservative composition comprising micronized copper and copper-amine complex, wherein the copper component of the copper amine complex is from about 5% to about 50% by weight, based upon the total weight of copper in the composition. The copper amine complex serves to avoid wood surface “chalking” that is otherwise attributable to the presence of micronized copper in copper-based slurries used to treat wood products. In addition, the copper-amine complex enhances the antimicrobial efficacy of the composition when used in wood treatment applications by facilitating cell wall penetration of the treated wood.
