A description is given of a wood-encased pencil comprising a casing and a core, the casing consisting of wood material impregnated with a saccharide component, the saccharide component comprising at least one mono-, di- or oligosaccharide in solution in a vehicle.

Disclosed herein are compositions and methods for treating wood to give it a desirable color that is durable over time, while at the same time rendering the wood resistant to fungal decay and insect attack. The wood may be pressure treated in a two-step process whereby the wood is first treated with a wood preservation composition, and then treated with a composition comprising pigments, or vice versa. Alternatively, the wood may be simultaneously treated with a composition comprising a wood preservative and a composition comprising pigments.

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

In a method for treating wood, wherein a wooden body is impregnated with a polymerizable compound which is polymerizable by oxidation, the polymerizable compound is brought into contact with an oxidizer in the wooden body in order to polymerize the polymerizable compound in situ. The polymerizable compound applied therein comprises a heterocyclic compound with nitrogen and/or sulphur as heteroatom. The oxidizer is brought into solution and the wooden body is saturated with a solution of the oxidizer. The wooden body is subjected to a vapour phase of the heterocyclic compound under an increased pressure and the heterocyclic compound is polymerized in situ in the wood.

A durable palm fiber composite material is obtained by impregnating an unprocessed palm bark in a resin adhesive solution prepared by using a palm leaf as a raw material and then hot-pressing. The palm bark is dried under a natural state without additional processing. The palm leaf is made into a tannin resin adhesive solution under the effect of additives such as furfuryl alcohol, paraformaldehyde, and others. A pH value of the adhesive solution is controlled to be 9-11. A solid content is 40-60%. An adhesive amount applied to the palm bark by the resin adhesive solution is 800-1500 g/m.sup.2. Odd number of layers (three or more layers) of palm barks that are impregnated by the resin adhesive solution and are hot-pressed to the composite material. Hot-pressed parameters are as follows: the temperature is 150-180 C. the unit pressure is 0.8-1.5 MPa, and the time is 10-30 s/mm.

A multifunctional broad spectrum antimicrobial composition is described. The composition can be incorporated into a wood preservative, or used as an additive to provide antimicrobial properties to water-based wood coatings. The composition is a concentrated water-miscible emulsion containing 3-iodo-2-propynyl N-butylcarbamate (IPBC), carbendazim (BCM) and propiconazole (PPCZ), and has antimicrobial activity against a wide variety of fungal organisms, including surface molds, blue stain fungi and wood rotting fungi. The composition can act as an in-can preservative and is useful for antimicrobial protection of wood and wood-based substrates.

Wood preservative compositions comprising a particulate copper compound in a solvent carrier with low aromatic content. Particulate copper dispersions in this composition demonstrated superior stability, and wood treated with the composition is protected from attack by wood decay fungi and termites. The invention is also directed to wood preservative compositions comprising: (a.) a biodegradable organic solvent carrier selected from the group consisting of vegetable oil, renewable resource oil, and biodiesel; (b.) a dispersion of solid particles of a metal compound having a particle size between about 0.005 microns to about 10 microns; (c.) an organic biocide; and (d.) a dispersant; ratio of the dispersant to the metal compound is from about 1:500 to about 100:1 (wt/wt). The invention is also directed to compositions comprising penflufen and solvent carriers. The invention is also directed to methods of treating wood using the compositions, and wood treated with the disclosed compositions and methods.

Here are described boroxine-containing compounds and their compositions for the treatment of wood. For instance, the treatment of wood includes its protection against moisture and/or degradation caused by insects or microbes.

The present application relates to wood treatment. More specifically, the present application relates to wood treatment compositions having antimicrobial properties, methods using the same and wood products treated therewith. The present application includes a wood treatment composition comprising: an antimicrobial additive comprising at least one tannin; and a water-based solvent. The present application also includes a method for treating a wood product to stop or prevent microbial growth applying a wood treatment composition on the wood product, and optionally applying a wax; wherein applying the wood treatment composition comprises heating at least one surface of the wood product and impregnating the composition.
