Imidazole compound-containing hardening agent composition, method of preparing the same and thermosetting epoxy resin composition.

摘要

Disclosed is a hardening agent composition for epoxy resins, which comprises a low-reactive hardening agent, an imidazole compound and a zeolite, wherein the imidazole compound is substituted on the imidazole nucleus by at least one of (a) and (b): (a) an alkyl group having 2 or more carbon atoms and a polar group, and (b) an alkenyl group. In another aspect of the invention the hardening agent composition is combined with an epoxy resin to form a thermosetting epoxy resin composition, capable of hardening under heat to give a hardened product having a remarkably elevated adhesion strength. A method for forming the hardening agent composition is also disclosed.
