Alkanolamine-Based Adduct as Latent Accelerator for Epoxy/Dicyandiamide: Statistical Approach to the Relationship Between Adduct Ingredients and Cure Characteristic of One-Pot System

Through the addition reaction of epoxy, phthalic anhydride and different types of alkanolamine, we developed adducts as latent accelerators for one-pot epoxy/dicyandiamide system. The analysis of variance (ANOVA) technique was employed to evaluate the relationship between the adduct ingredients, namely alkanolamine type, alkanolamine and phthalic anhydride content, and cure peak temperature (Tp) of one-pot system. Results showed that the Tp was affected by all three factors while the degree of influence of alkanolamine type on accelerating the curing reaction was higher than that of the others. Moreover, increasing the alkanolamine amount promoted while higher amount of phthalic anhydride demoted the accelerating ability of accelerator.
