Abstract: Disclosed is a method of preparing compositions comprising submicron particles of a metal salt. The method comprises providing an aqueous alkaline solution comprising a metal, one or more ligand that forms a soluble complex with the metal under alkaline conditions, and optionally one or more dispersant; and admixing the solution and a source of carbon dioxide to reduce the pH of the solution such that submicron particles of a metal salt precipitate. Also disclosed are compositions prepared by the method. Also disclosed is a method of treating a substrate, such as lumber, comprising applying the compositions and substrates treated by the method.

Abstract: Compositions and methods for use in treating, in particular, lignocellulosic substrates such as lumber, are provided; wherein said compositions comprise a preservative or biocidal species, other than boron, in the form of a glycolate. The methods may be used for the purpose of, for example, preventing the growth of pest organisms, or for providing other specific properties to the substrate.

Abstract: This invention relates to compositions for, and methods of, delivering treatment compounds to lignocellulosic substrates, wherein the solvent is recovered using RF energy.

Abstract: Method of delivering compositions to organic substrates, particularly lumber. Method involves heating a target zone of the substrate and then applying the composition to the surface of the substrate wherein the temperature of the composition is lower than that of the target zone of the substrate. Compositions include biocidal, strength modifiers, waterproofing and polymers.

Abstract: A method of conditioning an organic substrate is described The method involves heating the substrate using RF energy under desired pressure conditions in a constrained environment At a desired time point, the pressure is rapidly reduced causing any water present in the substrate to rapidly boil and convert to steam.

Abstract: A biocidal composition useful for providing antifungal or antibacterial protection to a substrate such as wood, the composition comprises in its use form a use solution of pH of 4 or below containing at least one biocide and a source of free phosphite ions. A preferred source of phosphite ions is phosphorous acid. The composition allows deep penetration of a biocide such as copper oxine into where it can be fixed by pH change and confer a degree of protection beyond that hitherto obtained with such a biocide simply applied to the surface of the substrate.
