Provided herein are polymers, including polyureas, polyurethanes, and polyurea-polyurethane hybrids, made from an isocyanate, a secondary polyetheramine, an aspartic ester amine, and optionally a polyol. The secondary polyetheramine may be used in combination with the aspartic ester amine to increase flexibility or modify other properties and lower cost of the final polymer product while maintaining a desirable cure time. |
