Abstract

Abstract: The catalytic reactivities were studied for the curing of epoxy resin E-51/methylated te-trahydro-o-phthalic anhydride (MTHPA) catalyzed by Cr(Ⅲ) chelates. It is indicated that the most active catalysts are the Cr(Ⅲ) chelates of 5-tertiary butyl furan-methanoic acid, 5-isopropyl furan metharsoic acid and 2-ethyl-hexanoic acid. The effect of various ligands on the reactivities of the Cr(Ⅲ) chelates is discussed. The curing course of the reactions of E-51/MTHPA catalyzed by Cr (Ⅲ) chelates were also studied.

Key words: Epoxy resin, Metal chelates, Curing
