Abstract: Multi-component materials are substantially homogeneous and fully curable and comprise an elastic filler, an isocyanate curing agent, and a polyol resin ingredient that when combined produce a polymeric matrix, polyurethane and/or polyurea, having the filler dispersed therein. The material has a variation in polyisocyanate weight ratio of up to 350%. The filler is ground rubber tire particles sized 20 mesh or smaller. The mix weight ratio of the curing agent to resin ingredient is from about 40:100 to 140:100. The material is made and dispensed using a system configured to combine a heated mixture of the resin and filler with the curing agent at a desired variable mix ratio. A controller is used to provide the desired mix ratio and permits “on the fly” adjustment of the mix ratio while the resin and curing agent is being dispensed.
Abstract: A method for producing a vegetable oil-derived polyol having increased hydroxyl functionality by reacting a vegetable oil with an oxidizing agent in the presence of an organometallic catalyst is provided. The resulting higher functionality polyols derived from vegetable oil produced by the process are also provided. Also provided is a method for decreasing the acid value of a vegetable oil-derived polyol by reacting the vegetable oil-derived polyol with an epoxide component in the presence of a Lewis base catalyst. Urethane products produced using higher functional vegetable oil-derived polyols and/or lower acid vegetable oil-derived polyols are also provided.

Abstract: A building material composite that includes a building substrate at least partially lined with a urethane material. The urethane material of the present invention is typically the reaction product of an A-side that includes an isocyanate and a B-side that typically includes: a blown vegetable oil, a cross-linking agent, and a catalyst; a blown vegetable oil and a multifunctional alcohol; or an esterified polyol and a catalyst where the esterified polyol is typically the reaction product of a first polyol and a blown vegetable oil.

Abstract: A filled multi-component material applied by a dispensing system is disclosed. The material can be produced by mixing a first reactive component comprising a resin and a filler with a second reactive component comprising a curing agent. The filler can comprise a hard filler and/or an elastic filler such as ground recycled tire material. The first reactive component and the second reactive component can be fed to a dispensing apparatus and mixed by a static mixer, each of which can be disposable. The mixture can then be dispensed onto a surface using air spray, airless spray or extrusion, for example. When applied to a surface, the mixture typically polymerizes and entrains the filler materials to provide a protective layer having improved properties. In certain embodiments, the filler materials can include recycled tires that have been ground into fine particles, providing environmentally friendly new products from old tires that typically end up as landfill.
