COMPOSITION BASED ON FATTY ACIDS AND PARAFFIN DERIVATIVES FOR PROTECTING LIGNOCELLULOSIC MATERIALS

摘要

A protective composition comprising hydrocarbon in aqueous form and/or as a colloidal mixture of solvent, zirconium and/or aluminum is used for wood and timber materials. The hydrocarbon has 4-60 carbon atoms. It has hydroxyl groups that act as reactive groups. The hydroxyl groups comprise n-methylol, ketene, ketene-dimer, optionally cyclic anhydride, or groups of isocyanates. An independent claim is included for wood or timber material impregnated with the protective composition as above.
