Abstract
A process for forming a polyurea coating on a wood composite substrate comprises the steps of applying an isocyanate to an edge of the wood substrate to form a pretreated edge and applying a polymer latex to the pretreated edge to form the polyurea coating. This polyurea coating provides excellent protection against the penetration of water through the edges and into the interior of the wood composite material and wood composite materials having this polyurea coating have significantly less edge swelling and adsorb considerably less water than wood composites that have no such protective coatings.
