ADHESIVES， REACTION SYSTEMS AND METHOD FOR PRODUCING LIGNOCELLULOSIC COMPOUNDS.

Adhesives， reaction systems， and processes for the production of lignocellulosic composites. The reaction system comprises a multi-component adhesive and a lignocellulosic substrate. The lignocelluosic substrate comprises a plurality of lignocellulosic adherends and is preferably a mass of wood particles. The multi- component adhesive comprises a multi-functional isocyanate， a hydrophilic polyahl， and an organotransition metal catalyst. The multi-component adhesive is characterized by being formulated into at least two mutually reactive chemical component streams. The process comprises the separate application of the mutually reactive chemical component streams of the multi-component adhesive to the lignocellulosic substrate， followed by forming and pressing the adhesive treated substrate under conditions appropriate for curing the adhesive and forming a lignocellulosic composite article. The adhesives， reaction systems， and processes are particularly well suited for the production of oriented strand board (OSB).
