A method includes synthesizing pigment in situ in a porous material and includes impregnating the porous material with a first reactant, and subsequently impregnating the porous material with a second reactant to form the pigment in situ. The method is contrasted with applying a pigment to a material via an external surface of the material, where pigment penetration is limited, and the pigment is not protected from environmental hazards such as ultraviolet light. Forming the pigment within the cells of the porous material provides pigmentation throughout the material and protects the pigment over the life of the product.

A two-part flame-retardant, a flame-retardant oriented strand (OSB) and method for forming a flame-retardant OSB is provided. The two-part flame-retardant composition includes an aqueous solution containing a water-soluble flame-retardant and a flame-retardant powder that is incorporated into an oriented strand board without substantially affecting the mechanical properties of the oriented strand board. The method includes applying the aqueous solution containing a water-soluble flame-retardant to an oriented strand board furnish and applying a flame-retardant powder to the wetted furnish, without requiring an additional drying step.

The invention relates to an agent, in particular a flame retarding agent and/or a fire retarding agent, for reducing the combustibility and flammability of various materials or matters, e.g. like wood and wood products, textiles, paper, cardboard, fibers and fabrics, paints, including composites and/or composite materials therewith, the manufacture of the composition and methods of using the agent and/or the corresponding combination of its constituents to reduce combustibility and flammability. An exemplary composition in dry form (powder) for 1 l of aqueous solvent, in particular for 1 l of water, contains borax in an amount of 30 to 70 wt.-%, boric acid of 30 to 70 wt.-%, sodium chloride (NaCl) in a maximum amount of less than 5 wt.-%, and, if desired, urea in an amount up to 5 g; based in each case on the composition as 100 wt.-%. However, the compositions are preferably free from urea.

A process for producing nano veneers generally involving: placing a veneer to be treated in a vacuum vessel; adding a nano carbon powder and nano silicon dioxide suspension in the vacuum vessel; reducing the pressure in the vessel over a first period of time; increasing the pressure in the vessel; letting the contents of the vessel rest over a second period of time. The veneer may optionally be subjected to ultrasonic treatment, ultraviolet solidification treatment, or subsequent pressurization treatments to obtain the final nano veneer product. As a result, veneer manufactured using embodiments of the present invention will have the advantages of high strength, wear resistance, pollution resistance, acid and alkali resistance, water segregation and decay resistance.
