The Synthesis of a Polyaspartic Acid Ester and Development of the Coatings

Abstract:

A new type of polyaspartic acid ester (PAE) was synthesized by double alkyl malay acid ester and bis-(p-aminocyclohexy) methane (PACM) via a Michael addition reaction. The Fourier transform infrared spectrometer shows the reaction can take place in room temperature. The dynamics of the reaction were investigated by mercaptan-iodine titration analysis method at 57°C and 67°C. The results showed the reaction order between double alkyl malay acid ester and bis-(p-aminocyclohexy) methane (PACM) was three. The solvent free polyaspartic polyurea coating was developed with the synthesized resin and the properties were tested with good results.
