A curable epoxy resin composition comprising (I) an epoxy resin having on average more than one epoxy group per molecule, (II) a specific Mannich base and, optionally, (IV) a specific amino compound, with the amount of the Mannich base (II) being 1 to 50 parts by weight per 100 parts by weight of the resin (I) and the amount of any amino compound (IV) being 5 to 200 parts by weight per 100 parts of the resin (I), is low in odor and therefore easy to handle, can be excellent in low-temperature curing characteristics, and its cured product can exhibit excellent resistances to water, chemicals and amine blushing, and have excellent physical properties. The resin can be constituted as a two-liquid type having the resin (I) separate from the base (II) and any amino compound (IV), or as a three-liquid type in which (I), (II) and (IV) are separate from one another. The curing agent comprising the Mannich base (II), both with and without the amino compound (IV), is also disclosed. |
