A wood preservative composition and method for preserving wood by contacting wood with said composition comprising a polyurethane polymer, non-aqueous solvents, and a wood preservative active.

Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

An invention relates to thermal or thermomechanical processing of hygroscopic material to adjust the material properties. The invention concerns a modification arrangement for the hygroscopic material. The modification arrangement comprises a modification unit (202) and a fluid container (204) that is coupled with a control valve (205) to at least one fluid aperture (203). The modification arrangement is configured for heating the hygroscopic material in the modification unit (202) to extract water from it and, in response to opening of the control valve (205), leading fluid from the fluid container through said at least one fluid aperture (203) into the modification unit (202). The modification arrangement further comprises a treatment agent (207) added to the fluid so that the treatment agent (207) is absorbed into the hygroscopic material and modifies it. The treatment agent (207) includes at least one of the following ingredients: a preservative, a dye, a pigment, an aroma, an odour eliminator, a pesticide, an impregnation ingredient, or a fire retardant.

The present invention provides a solution and related composition of matter and methods which synergistically improves a fungicide's effectiveness in resisting undesired fungal growth. The invention also provides wood and wood products which have been treated with the solution, method or compound.

A protectant and sealant solution and method of use thereof, configured to protect wood from premature decay when disposed in contact with the earth. The solution is composed of processed hemp oil which is mixed with bio-diesel and other oils to form the protectant solution. The wood is then impregnated with the solution via pressure treatment within a retort cylinder. The solution is configured to protect utility poles and other wooden construction members which are known for prolonged contact with soil. The solution is designed as a safe replacement for pentachlorophenol solutions which have been found to be harmful to the soil and water table.

An integrated reed protection and storage system is provided. The system includes a controlled solution container. The system also includes a sponge material positionable within the container. Further, the system includes at least one reed holder positionable around the sponge material. Additionally, the system includes at least one reed, the at least one reed positionable on the at least one reed holder. The at least one reed is configured to contact a surface of the sponge material.

A composition for preparing an emulsion or microemulsion, the composition including the following components (A) to (D): component (A): an active ingredient having a solubility in water at 20 C. of 200 ppm or less; component (B): a water-insoluble solvent having no alcohol group; component (C): at least one nonionic surfactant selected from the group consisting of a polyoxyalkylene alkyl ether, a polyoxyalkylene alkenyl ether, a polyoxyalkylene alkyl amino ether, and a polyoxyalkylene alkenyl amino ether; and component (D): a monohydric alcohol having 8 to 12 carbon atoms.
