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.
