    摘要: Methods of preparing a polyaspartic ester composition comprise reacting a primary diamine reactant composition with a diester reactant composition under conditions to prepare a polyaspartic ester composition having a primary amine value of less than 35 mg KOH/g wherein, at the time of the reaction, the combined water content of the primary diamine reactant composition and the diester reactant composition is less than 300 ppm. Compositions and methods of use of the compositions are also described.
