| 20080207796 | Furanic resin aggregate binders and method - Broadly, the invention provides for newly available bio-derived formaldehyde free furanic materials for aggregate binding. The specific example case is aggregate binding for forms used in the metal casting process. The new materials make possible higher productivity and lower phenol, formaldehyde, urea, and/or furfuryl alcohol content in the metal casting form-making process. It is expected that the formulations will work well in other aggregate binding situations as well. | 08-28-2008 |
| 20080207847 | Furanic-modified amine-based curatives - Difunctional aromatic diamines (e.g. Ethacure® 100 and 300) are derivatized with furan-2,5-dicarboxylic acid (FDCA) to form FDCA-derived bisamides; the derivatives have enhanced curative properties when used as curatives for polyureas, hybrid epoxy-urethanes, hybrid urea-urethanes, chain extenders for polyurethane and polyurea elastomers, and also for reaction injection molding (RIM) products. | 08-28-2008 |
| 20100081774 | FORMALDEHYDE FREE BINDERS - New polyols; oligomers, and polymers made from the polyols; and binders made from the new polyols, oligomers, or polymers that can be used in binders, where the binders typically include one or more polyols, and a polyfunctional acid or a polyfunctional nitrile. | 04-01-2010 |
| 20100280186 | FURANIC-MODIFIED AMINE-BASED CURATIVES - Aromatic polyamines are derivatized with polycarboxylic acids or their derivatives to form polyamine amides) containing pendant amine groups; the derivatives have enhanced curative properties when used as curatives for polyureas, hybrid epoxy-urethanes, hybrid urea-urethanes, chain extenders for polyurethane and polyurea elastomers, and also for reaction injection molding (RIM) products. | 11-04-2010 |
