Kinetic Studies on Epoxy Resins Cured with a Novel Polyamine

Abstract

Differential scanning calorimeny was used to study the cure kinetics of three epoxy resin systems cured with two hardeners: diaminodiphenylmethane (DDM) and a poly (keto-amine) (PA). The results showved that the curing of the epoxy resins by PA occurs at higher temperatures and the activation energy for PA curing was higher compared with the DDM curing process, showing the er reactivity of PA.
