ABSTRACT:
A wood processing composition comprising a dimensional stabilizer which penetrates wood and restrains its swelling and shrinkage to prevent cracking and to give it dimensional stability, and a hardening filler composed of synthetic resins which hardens after penetrating wood to prevent the dimensional stabilizer from flowing away from said wood, fills the cavity of the wood to restrain its shrinkage, and protects the wood against decay and damage by termites. It preferably further contains a flame retardant consisting of at least one of a phosphoric acid compound and dicyandiamide, and a water-soluble flame-retardant solution containing urea and a 37% aqueous solution of formaldehyde by weight. Wood is impregnated with the composition by appropriate means and, after drying, it may be impregnated with a surface reinforcing synthetic resin. The wood as processed is free of any unnatural color, is harmless, and retains a durable surface which is characteristic of wood.
