Abstract: The present invention provides an improved product and method of applying a product to remedy any deficiencies of wood and wood products while maintaining the quality of current processing and increasing efficiency. In one aspect of the present invention, a method of repairing wood or wood products comprises analyzing a wood or wood product for a defect, the wood or wood product having a surface; identifying the defect in the wood or wood product; identifying a location of the defect in said wood or wood product; preparing for repair the surface of the wood or wood product in the location of said defect; applying a two-component urethane to the surface of said wood or wood product in the location of the defect, said two-component urethane comprising a polyol mixture and an isocyanate; and, curing the two-component urethane for a period of time.

Abstract: A multi-component, chemically-curing, non-cellular, polymeric composition includes a resin component having a resin density, a reactive component having a reactive component density, and an aggregate component having a spherical shape, a diameter of about 0.1 mm to about 10 mm and an aggregate density. The density of the aggregate component is within 2 lbs/gallon of the density of at least one of the resin component or the reactive component.

Abstract: The disclosed composite wood particulate products, adhesives contained in such wood particulate products, and methods of making the adhesive and the wood particulate products employ an aldehyde-free adhesive, and more specifically a formaldehyde-free adhesive. The aldehyde-free adhesive includes an inert additive that extends a resin, such as an isocyanate resin, and forms an evenly dispersed, less expensive polymeric adhesive admixture. The extender-filler of the resin is mixed with water to form a slurry. The slurry can then be mixed with a resin, like the isocyanate resin, to form the adhesive. Various rheology modifiers can be added, if desired, to the extender-filler or the slurry. The adhesive can be blended with wood particles to form a mat that is then pressed into a composite wood particulate product.
