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.

Abstract: An apparatus for distributing a soap based release agent upon a surface comprising; a means for metering a controlled quantity of a liquid metallic soap into a pressurized water stream to form a pressurized aqueous solution having a controlled dilution ratio of soap to water, at least one manifold connected to receive the pressurized aqueous solution, and a plurality of nozzles mounted upon the manifold to uniformly distribute the pressurized liquid solution upon at least one surface. The surface may further be defined as a planar surface, moving unidirectional along a fixed path at a predetermined variable speed and defined by a surface area of length multiplied by width. The planar surface has a fixed width, wherein the surface area moving past a fixed point for a predetermined period of time is a function of the speed of the planar surface moving past the fixed point.
