Abstract

See full text

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.
