A composition for treating cellulosic materials is provided. The composition comprises a dispersion of micronized additives. The dispersion comprises additive particles with diameters in the range of 0.001 to 25 microns. Also provided is a method for the application of the additive-containing composition to wood, as well as wood products which have been treated with the composition.

The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.

A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.

Disclosed herein are compositions including a dispersion of solid particles of a substantially insoluble copper compound, and an organic biocide, wherein at least 20% of all particles of the composition have a particle size greater than 25 microns. Also disclosed herein are methods of making and using the same.

The invention relates to biocidal mixtures comprising penflufen-containing polymer particles, copper compounds and specific alkanolamines and to the use thereof for protecting wood and wood products, and also to wood preservatives comprising biocidal mixtures and optionally further active ingredients.

To provide a board material processing composition allowing for production of a board material laminate that is non-combustible and is excellent in adhesion performance. In order to solve this problem, a board material processing composition inhibiting combustion of a board material due to heating, comprises: a carbonization promotion component, being inorganic, promoting carbonization of an organic component within the board material at the heating; a chain inhibition component, being inorganic, inhibiting a reaction chain to a neighboring component due to a product of endothermic decomposition generated at the heating; and binder particles, being inorganic and hydrophobic, bonding the organic component within the board material to the carbonization promotion component and the chain inhibition component, wherein the carbonization promotion component includes boric acid, the chain inhibition component includes ammonium dihydrogen phosphate, and the binder particles include silica sand.

Techniques and products are described for coloring acetylated wood products. An acetylated wood product can be impregnated by a coloring medium within a chamber and the colorant or colorants contained within the coloring medium can be fixed to the acetylated wood product by the application of heat or by application of radio frequency radiation to color any external surface or interior region of the acetylated wood product which has been impregnated by the coloring medium.
