Wood Plastic Composites (WPC), OSB, chipboards and particle boards with higher durability and quality

Scientists at the University of Göttingen developed a novel timber protecting composition based on fatty acids and paraffin derivatives for protecting Wood Plastic Composites (WPC), chipboards and particle boards. Particularly the durability and quality is increased. Developed was a pre-treatment of the lignocellulosic material by paraffines containing an alumina catalyst or by activated fatty acids. These residues contain N-methylol groups as a reactive group, and do not only adhere to the basic material, but chemically react with the hydroxyl groups of lignocellulosic material and remain covalently bound to the material.
