Kind Code:
A1
Abstract:
[Problem] To provide a fast-curing epoxy resin composition having a long pot life. [Solution] An epoxy resin composition containing a curing agent A, a curing agent B, a curing agent C, an epoxy resin D, an epoxy resin E, and resin particles F, wherein the epoxy resin composition is characterized in that: the curing agent A is an aromatic polyamine having two substituents each at the ortho position to the amino group; the substituents are selected from alkyl groups, aromatic groups, and halogen groups; the curing agent B is an aromatic polyamine that is liquid at 25°C; the curing agent C is an aromatic polyamine; said aromatic polyamine is an aromatic polyamine having only one electron-donating group at the ortho position to the amino group or having no substituent at the ortho position; the epoxy resin D is configured from an epoxy resin configured from a monomer including four or more glycidyl groups; and the epoxy resin E is configured from an epoxy resin configured from a monomer including two or three glycidyl groups.
