  • Patent number: 9920228
    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.
    Type: Grant
