A wood preservative composition comprising a synergistic combination of RH-287 and one or more co-biocides. Examples of such co-biocides include, fenpropimorph, cyproconazole, imazalil and propiconazole. The efficacy of potential wood preservative compositions can be tested by a simple test provided herein.
A01N 25/00 - Biocides, pest repellants or attractants, or plant growth regulators, characterised by their forms, or by their non-active ingredients or by their methods of applicationSubstances for reducing the noxious effect of the active ingredients to organisms other than pests
A01N 25/34 - Shaped forms, e.g. sheets, not provided for in any other group of this main group
Provided is a method for coloring and, optionally, preserving wood and wood products. The method comprises application of pigment dispersions, and optionally biocide dispersions, to wood such that the wood is impregnated. A composition for coloring and, optionally, preserving wood is disclosed, comprising dispersions of micro nized pigment and, optionally, micronized biocide.
Provided is a method for improving the dimensional stability of wood and wood products. The method comprises impregnation of wood with fluorocompounds. In one embodiment, the method comprises the impregnation of wood or wood products with a composition comprising fiuoro- polymer emulsions and/or dispersions.
The present invention relates to a method for producing metal-containing amine solutions by reacting a metal or metal-containing compound, in particular, copper or a copper-containing compound, with an amine, carbon dioxide and an oxidizing agent. The resulting metal-amine solution can then be used to formulate a variety of metal-based woods preserving products.
A method for the preparation of a composite product, as well as the composite product. The composite product comprises at least two layers. At least one of the layers is of wood or another cellulose-containing material. The process comprises differentially treating the layers prior to, during, or after the lamination of the layers into a composite product.
Provided are compositions for improving the water-resistance and dimensional stability of wood and wood products. The compositions comprises wax and oil components, and can be applied as liquid compositions comprising little or no water. Also provided are methods for the application of the compositions to wood.
B05D 3/10 - Pretreatment of surfaces to which liquids or other fluent materials are to be appliedAfter-treatment of applied coatings, e.g. intermediate treating of an applied coating preparatory to subsequent applications of liquids or other fluent materials by other chemical means
Provided is a composition and method for the preservation of wood. The composition comprises 1) an azole and/or quaternary ammonium compound component and 2) a pyrethroid compound component such that wood treated with the composition has a greater decay resistance than wood treated to the same azole retention with the azole alone. The method comprises the application of the composition to wood.
Provided is a preservation composition having a large-particle distribution which can effectively penetrate and preserve wood. The composition comprises a particulate dispersion of biocidal particles such that at least about 3 weight percent of the particles have diameters are greater than about 0.5 micron, and at least 98 wt% of the particles have diameters of less than about 10 microns. Also provided is a method for preserving wood with the composition.
B05D 1/18 - Processes for applying liquids or other fluent materials performed by dipping
B05D 7/22 - Processes, other than flocking, specially adapted for applying liquids or other fluent materials to particular surfaces or for applying particular liquids or other fluent materials to internal surfaces, e.g. of tubes
A water-proofing process for wood and wood products is provided. The process comprises treating pre-dried wood or wood product with a mixture comprising one or more drying oils and one or more high boiling point oil. The process can be carried out at positive pressures and can also be used to treat wood or wood products with temperature sensitive additives.
