Furanic Modified Amine-based Curatives
Difunctional aromatic diamines (e.g. Ethacure.RTM. 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.
