Patent ID: 10920068

Abstract:
Provided is a novel curable composition that is a two-pack type curable composition that includes an epoxy resin and a crosslinkable silicon group-containing organic polymer, excels in storage stability, and does not experience curing delays, an increase in viscosity of the base material, or the deterioration of the base material such as gelation or the deposition of insoluble material. Also provided is a novel curable composition that excels in storage stability even when water is added to improve deep portion curability. A two-pack type epoxy composition according to the present invention contains: a base material that includes (A) an epoxy resin, (B) a compound having an Si—F bond, and (C) an alkoxysilane not having at least one group selected from the group consisting of a primary amino group, a secondary amino group, and a mercapto group; and a curing agent that includes (D) a crosslinkable silicon group-containing organic polymer, and (E) a tertiary amine compound.
