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.
一种可固化的环氧树脂组合物,包括(I)平均每个分子具有一个以上环氧基团的环氧树脂,(II)特定的曼尼希碱,以及可选的(IV)特定的氨基化合物,其中曼尼希碱(II)的用量为每 100 重量份树脂(I)1 至 50 重量份,任何氨基化合物(IV)的用量为每 100 重量份树脂(I)5 至 200 重量份、低气味,因此易于处理,具有优异的低温固化特性,其固化物具有优异的耐水性、耐化学性和耐碱性,并具有优异的物理性能。该树脂可以是树脂(I)与基质(II)和任何氨基化合物(IV)分离的二液型,也可以是(I)、(II)和(IV)相互分离的三液型。此外,还公开了由曼尼希碱(II)(含或不含氨基化合物(IV))组成的固化剂。
