  • Patent number: 10894337
    Abstract: According to the present invention there is provided a method of treating timber with a creosote-containing preservative formulation adapted for use at substantially ambient temperature. The formulation comprises: creosote; one or more surfactants such that when diluted with a predetermined quantity of water, the creosote is present as an oil-in-water macroemulsion or microemulsion; and optionally, an anti-foaming agent and/or a fire retardant. It is found empirically that the inventive concentrate allows for the use of creosote, a known-effective biocide, without many of the drawbacks inherent in such use.

  • Patent number: 9045681
    Abstract: According to the present invention there is provided a carrier formulation adapted to operatively support a preservative or preservative mixture within a material for treating wood, said carrier formulation comprising water and one or more water-miscible, water-soluble or water-emulsifiable compounds wherein said carrier formulation provides for preservative penetration and substantial preservative retention within the treated wood; and wherein the treated wood requires relatively little post-treatment drying. The carrier formulation provides for substantially complete or envelope penetration of the preservative within the treated wood.

  • Publication number: 20140147691
    Abstract: The present invention relates to a preservative formulation for use in treating wood or other cellulosic materials, said formulation comprising: at least one biocidal metal compound; at least one preservative; and an aqueous carrier, wherein the preservative formulation has an uptake in the sapwood of less than about 220 l/m3 yet achieves substantially full penetration of the sapwood. Preferably, the preservative formulation is copper/tebuconazole in a ratio of about 25/1 w/w; and the wood is around 25 mm in thickness—for instance, decking timber.

  • Publication number: 20050038182
    Abstract: A process for treating wood comprising: a) impregnating the wood with a solution of furfuryl alcohol; b) allowing the impregnated wood to sit so as to permit diffusion of the furfuryl alcohol solution into the wood; and hot pressing the wood under conditions to effect polymerization of the furfuryl alcohol within the wood.
