摘要： A polyaspartate composition can include a reaction product of a diamine and an amine-reactive component. The amine reactive-component can include a diester and an acrylate combined at an equivalent ratio of diester equivalents to acrylate equivalents of from less than 0.9:greater than 0.1 to greater than 0.3:less than 0.7. The diamine and the amine-reactive component can be combined at an equivalent ratio of diamine equivalents to amine-reactive component equivalents of from 1:0.8 to 0.8:1.

摘要： A polyaspartate composition is provided which comprises a reaction product of a diamine and a diester reacted at a ratio of diamine equivalents to diester equivalents of from 1:0.95 to 1:0.50. The polyaspartate compositions of the invention may be combined with polyisocyanates to produce polyurea compositions, e.g., coatings, adhesives, sealants, composites, castings, and films, which exhibit a faster cure time along with faster development time for physical properties such as hardness and tensile strength.
