Abstract: An aqueous dispersion of octylisothiazolinone has been found to be useful for delivering OIT to wood for protecting the wood from fungal discoloration. The OIT dispersion can be applied to the wood to develop a protective barrier of preservative relatively at or near the exterior surface of the woodpiece.

Abstract: An aqueous dispersion of octylisothiazolinone (“OIT”) has been found to be useful for delivering OIT to wood for protecting the wood from fungal discoloration. The OIT dispersion can be applied to the wood to develop a protective barrier of relatively preservative at or near the exterior surface of the wood piece.

Abstract: A penetration indicator composition has been discovered which is soluble in solvent-based wood treating solutions, normally invisible to the human eye, and capable of exhibiting a visible color under test conditions. The indicator composition includes a hydrophobic borolane or a hydrophobic borate ester which exhibits a visually detectable color under the influence of a color change reagent. The new indicator composition is chemically stabile under wood treating conditions and detectable at relatively low ranges of concentration. Oil-soluble preservatives such as pentachlorophenol, iodopropynyl butylcarbamate, propiconazole, and tebuconazole are compatible with the new indicator composition. Methods for indicating penetration of a non-aqueous solvent composition in wood or a wood-composite are also disclosed.

Abstract: An aqueous dispersion of octylisothiazolinone (“OIT”) has been found to be a superior vehicle for delivering OIT to wood for protecting the wood from discoloration by mold or fungi. The OIT dispersion can be applied to the wood by spraying, dipping or pressure treating, among other methods.
