Abstract: An analysis was made on the curing reactioiu of Zili-4 adhesive composed of epoxy restn 618, tertiary amine-catalyzed dicyamliamide and reinforcer polysulfone resin by using CDR-1 Differential Scanning Calorimetry (DSC). Two interrelated analytical method, Ellerstein's and Kissinger's method's,were used to process dynamic DSC data for characterizing the curing reactivity or the kinetie pirameters such as overall activation energy E,Reaction order,total reaction heat ΔH_t,curing reaction extent α,and reaction time.
