According to the present invention there is provided the use of one or more low aromatic or substantially low aromatic solvents as a carrier, for efficacious use within a preservative formulation for treating wood or other cellulosic species. The invention also provides for a wood preservative formulation comprising such a carrier. In an embodiment, the carrier is selected from the commercially-available range of Exxsol® D and Isopar® fluids.

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.

Wood markers and processes for durably marking and subsequently identifying both original grain wood products and wood-plastic composite products. The wood marker can be dispersed beneath the surface of the wood, where it is protected from the elements and may endure years of exposure to the elements. The wood marker is compatible with state-of-the-art pressure-treating processes and may subsequently be detected for authentication purposes by known analytical methods.

The present disclosure relates to use of an aqueous dispersion of siloxane for reducing grain puffing of a wood substrate and an article comprising an anti grain puffing coating. The article comprises (a) a wood substrate having at least one major surface; (b) an anti grain puffing coating directly applied on the major surface of the wood substrate, formed from an aqueous dispersion of siloxane; and (c) one or more coatings applied on the anti grain puffing coating, formed from an aqueous coating composition, wherein the siloxane contains one or more hydrophobic group and one or more hydrophilic group chemically bonded to its molecule skeleton; and wherein the siloxane has a particle size in the range of 5 to 100 nm.

A synergistic wood preservation composition comprising a polymeric betaine and 3-iodo-2-propynyl butyl carbamate (IPBC). Also, a method of controlling microorganisms that produce mold and/or sapstain on wood or wood products or wood coating solutions by applying to a wood or wood product or wood coating solutions the synergistic wood preservation composition to control the microorganisms.
