  • Copper/amine oxide wood preservatives
    Patent number: 6340384
    Abstract: The present invention provides a composition comprising an amine oxide and an aqueous copper amine complex. Another embodiment of the present invention is a method for preserving and/or waterproofing a wood substrate by contacting the composition with the wood substrate. Yet another embodiment is an article comprising a wood substrate and the composition of the present invention. This composition has high efficacy against fungi, including copper tolerant fungi such as brown rot and soft rot, and is phase stable at high concentrations. Additionally, the amine oxide in the composition may impart waterproofing properties. The composition of the present invention is halide free and is environmentally friendly.
