Patent number: 9920228Abstract: 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: GrantFiled: March 17, 2017Date of Patent: March 20, 2018Assignee: The Willamette Valley Company LLCInventors: Philip N.

Patent number: 5952053Abstract: This invention relates to a process for producing filled polyurethane elastomers, and more particularly to a process for producing highly filled polyurethane elastomers in which resin solid separation is substantially reduced. The separation rate of the solid particulate fillers contained in a filled polyol resin is significantly reduced, and the subject process can be optimized to lower the viscosity of the uncured liquid reaction mixture prior to curing same to form a solid, thereby substantially non-cellular filled polyurethane elastomer. The above-described benefits can be accomplished by reacting together a three-component polyurethane system comprising (a) a filled polyether polyol resin having a particulate filler material dispersed therein, (b) a polyisocyanate, and (c) a catalyst solution for reacting (a) and (b) to form said filled polyurethane elastomer.Type: GrantFiled: September 26, 1997Date of Patent: September 14, 1999Assignee: Willamette Valley CompanyInventor: Scott A.

In this way, the restored railroad tie can be reused in subsequent rail replacement operations. The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems. The used railroad tie provided has at least one spike hole located therein. In each the means defining a railroad spike hole is formed a polymeric plug. The polymeric plug comprises a substantially non-foaming, non-cellular polymeric material. The polymeric material preferably comprises a polyurethane. The polymeric plug infiltrates and tightly bonds with the railroad spike hole to prevent moisture infiltration. Thus, substantial tie rot due to moisture is impeded, and the leaky railroad spike hole is effectively and efficiently dammed to enable complete filling thereof.Type: GrantFiled: June 9, 1997Date of Patent: September 14, 1999Assignee: Willamette Valley CompanyInventors: Scott Adams Colby, Robert Mark Loomis, Amy Laverne Clement
