ABSTRACT:
This invention relates to a process for converting hemicellulose of lignocellulosic material into a thermoset, water-proof adhesive. In one embodiment of the invention the thermoset, water-proof adhesive is used for converting other components of the lignocellulosic material into composite products such as panel products, reconstituted lumber and moulded articles without the use of any other adhesive binders which are an essential part of the conventional dry process of manufacturing composite products, such as wood-based particleboard, waferboard, medium density fibreboard, et cetera.
