A transition metal acetylacetone was studied as latent accelerator in the curing of anhydride cured epoxy resin by DSC

TEA

and rotation viscometer technique. The results reveal that the metal acetylacetone serves as an latent accelerator for anhydride curable epoxy resin system

and the rate of curing is found to increase with enhanced concentrations of the metal chelate. The system provides very fast gel time at 160-180℃ and combined with very good storage stability (> two months). Curing kinetic studies reveal that the overall suring process follows first order kinetics. The electrical

mechanical and thermal properties of cured com-pound of epoxy resin system catalyzed by the MT(acac)n and BDMA accelerator and cured by anhydride was also studied and compared in this paper.
