| 20120064244 | VEGETABLE OIL-BASED COATING AND METHOD FOR APPLICATION - A method of applying a urethane material to a vehicle substrate that includes the steps of: providing a vehicle substrate; and applying a urethane material to the vehicle substrate where the urethane material typically includes the reaction product of an A-side that includes an isocyanate and a B-side that typically includes a blown soy oil, at least one polyol at least partially derived from petroleum, and a cross-linker. A vehicle composite that typically includes the vehicle substrate and the urethane material. | 03-15-2012 |
| 20110313074 | NOVEL POLYOLS DERIVED FROM A VEGETABLE OIL USING AN OXIDATION PROCESS - 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. | 12-22-2011 |
