METHOD AND KIT FOR TREATING WOOD WITH RED UNDERTONES
In a method for treating wood with red and/or pink undertones to bring it to the desired colour, the wood is provided with one or more finishing layers with the desired colour, and before the finishing layer is applied the wood is provided with a neutralization layer to neutralize the red and/or pink undertones of the wood to be treated. A kit of two different aqueous solutions, which are applied as a single composition for treating wood with red and/or pink undertones, is suitable for neutralizing the red and/or pink undertones of the wood to be treated. The composition is a mixture of a first and a second component, wherein the first component is a solution of a reactive dye in water and the second component is an aqueous alkaline solution, which is suitable for forming covalent bonds with the fibres of the wood to be treated.

WOOD ARTICLE AND PROCESS FOR THE PREPARATION OF THE WOOD ARTICLE
The present disclosure relates to a wood article and a process for preparing the wood article. In particular, the present disclosure relates to a wood article comprising a wood substrate comprising acidic substances and having at least one major surface; a sealing coating applied on the major surface of the wood substrate; and a Michael Addition curing coating applied on the sealing coating, wherein the sealing coating is formed by a sealing agent comprising one or more chosen from an aqueous latex of polyurethane acrylics polymer, an aqueous latex of carboxyl functional self-crosslinkable acrylics polymer, an aqueous latex of cationic acrylics polymer, an aqueous latex of polyvinyl acetate and a two-component polyurethane coating system; and wherein the Michael Addition curing coating is formed from a two-component curable coating composition.
Wood transaction instrument
In some examples, a method of manufacturing a densified wood transaction instrument includes boiling a sheet of wood in a chemical solution, compressing the boiled sheet of wood using a die in a press to form one or more features in the sheet of wood, during the compressing of the boiled sheet of wood, heating the boiled sheet of wood to create a sheet of densified wood, and attaching one or more payment elements to at least one of the one or more features formed in the sheet of densified wood to form a sheet of one or more densified wood transaction instruments.
Black coloring composition
The present application relates to the field of black coloring of materials made from wood, such as reconstituted wood panels or paper/cardboard. The black coloring composition for wood-based materials includes a black pigment, a reactive type black dye and water. It is also possible to prepare a dry extract for some special applications.

Method of treating lumber foundations in buildings
This invention provides method of treating a surface of exterior wood outside of buildings to inhibit the uptake of moisture into the wood by spraying on the surface of the wood an aqueous formulation consisting of one or more film forming non-chloride, long-chain polymers. The aqueous formulation forms a clear micro-film. Preferably, the long-chain polymer is polyethylene-vinyl acetate, polyurethane, or a combination thereof, wherein the clear micro-film contains no detectable volatile organic compounds. A clear colorant is added to the aqueous formulation to verify treatment. The clear colored micro-film maintains moisture content in the wood at 16 percent or less, allows for continued visual inspection of the surface of the wood for termite damage, does not rub off, get diluted with water, or become damaged by workers and pets who come into contact with the clear colored microfilm.
MULCH COLORING
Coloring systems and methods include a reservoir that holds a colorant. A vibrator motor is attached to the reservoir and applies a vibration to the reservoir to cause the colorant to collect at a bottom of the reservoir. An auger moves the colorant from the reservoir to an outlet.
