Wood treatment process and chemical composition

Treatment and preservation of wood, wood fiber products, and porous surfaces with a stabilized solution of periodic acid or iodic acid is provided.

Fire retardant for woody materials

Abstract of the disclosure A fire retardant for woody materials, which is an aqueous solution comprising 100 parts by weight as solids content of a water-soluble 3-(dialkylphosphono-propionamide) represented by the following general formula

Compositions and methods for treating cellulose-based materials with micronized additives

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.

Controlled release microbiocide for porous surfaces

Algal defacement of coated and non-coated porous masonry and wood construction materials is prevented by pre-treatment of the construction material with an aqueous composition of a copolymer that releases 2-propenal (acrolein) over time.

Additives for use in wood preservation

The present invention relates to a wood preservative formulation comprising a biocidal agent which is a copper or zinc ion complexed with an amino compound selected from the group consisting of ammonia, a water soluble amine or aikanoiamine and an aminocarboxyiic acid and a cationic polymer, as well as to aqueous treatment solutions comprising such a formulation and methods of treating wood or other cellulosic material utilising said formulation.

Low leaching antifouling organotin polymeric materials

LOW LEACHING ANTIFOULING ORGANOMETALLIC POLYMERIC MATERIALS ABSTRACT OF THE DISCLOSURE Objects which are designed to be submersed or submerged are rendered antifouling by using an organotin polymer wherein the tin is chemically combined in or bonded to the polymer. The polymer inhibits fouling of the exposed surface of the object while minimizing the effect on the surrounding environment due to reduced leaching of the organometallic compound from the polymer.

METHOD FOR RETURNING WOOD AND USE OF THE RETURNED WOOD

Method of pressure treating boards

A method for pressure treating wood products is provided wherein wood products are pressure treated in an aqueous solution of a silicate, a rheology modifier, a wetting agent and, optionally, borax; the aqueous solution having a pH of at least 9Ø A suitable dye can be added to the aqueous solution to color the wood product. The present invention is also directed to an aqueous solution for pressure treating wood and a wood product prepared according to the method of the present invention.

Sorbent material

Abstract Granular sorbent material comprising a granular high surface area support impregnated with a water soluble, essentially non-volatile primary or secondary amine with equivalent weight less than about 400 and bearing either zero or two carbonyl substituents attached directly to the amino nitrogen atom is disclosed. The resulting material can be used as the filtration media in respirators, powered air purifiers, room air purifiers, ventilation filters, exhaust filters, process gas filters and the like to reduce the formaldehyde content of air.
