Curable compositions contain an epoxide resin and, as curing agent, a mixture of (a) a silamine of the general formula ##STR1## wherein either m represents 1, in which case R.sup.1 represents the divalent residue of an aromatic, aliphatic, araliphatic, or cycloaliphatic diprimary amine after removal of two primary amino groups, and n represents zero or an integer of from 1 to 10, or m represents 2, in which case R.sup.1 represents the trivalent residue of an aliphatic triprimary amine after removal of the three primary amino groups, and n represents zero, and R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6, which may be the same or different, represent alkyl or aryl groups, and (b) a substantially anhydrous organic acid or a phenol. These compositions are stable for prolonged periods in the absence of water, but cure rapidly at room temperature or at elevated temperatures in the presence of water, which may be as water vapor or liquid water.
可治疗组合物包含环氧树脂和作为固化剂的混合物(a)一种通式为##STR1##的硅胺,其中m表示1时,R.sup.1表示芳香族、脂肪族、芳基脂肪族或环脂肪族二元一次胺去除两个一次氨基团后的二价残基,n表示0或1至10的整数;或m表示2时,R.sup.1表示脂肪族三元一次胺去除三个一次氨基团后的三价残基,n表示0,R.sup.2、R.sup.3、R.sup.4、R.sup.5和R.sup.6可以相同也可以不同,表示烷基或芳基基团;以及(b)基本无水的有机酸或酚。这些组合物在无水条件下稳定,但在存在水的情况下,在室温或升高温度下迅速固化,水可以是水蒸气或液态水。
