    • Capped amine hardeners for epoxy resins, which are reaction products of amines A having at least two primary amino groups, cyclic alkylene carbonates B, aliphatic carbonyl compounds C and compounds D having at least two groups which react with hydroxyl groups, such that in the first step, 0.1 to 1 mol of the primary amino groups for each 1 mol of the amine A are converted to hydroxyalkylurethane groups by reaction with the cyclic alkylene carbonate B, and the remaining primary amino groups are converted by reaction with the aliphatic carbonyl compound C in a second step to give ketimine or aldimine groups, and finally in the third step at least two of the molecules formed from A, B, and C are linked through reaction of the hydroxyl groups of the hydroxyalkylurethane groups with compound D. These capped amine hardeners are suitable for formulating water-dilutable monocomponent epoxy resin systems. The amines are released by addition of water, and are available for the curing reaction with the epoxy groups. Coatings formulated on the basis of this system are characterized by a very low content of auxiliary solvent. The cured coating films show outstanding leveling and film properties.
    • 作为具有至少两个伯氨基的胺A的反应产物的环氧树脂的包封胺固化剂,环状亚烷基碳酸酯B,脂族羰基化合物C和具有至少两个与羟基反应的基团的化合物D,使得在第一 通过与环状碳酸亚烷酯B反应将每1mol胺A的0.1〜1mol的伯氨基转化为羟基烷基氨基甲酸酯基,其余的伯氨基通过与脂肪族羰基化合物C反应而转化 第二步产生酮亚胺或醛亚胺基团,最后在第三步中,由A,B和C形成的分子中的至少两个分子通过羟基烷基氨基甲酸酯基团的羟基与化合物D反应而连接。这些封端的胺固化剂 适用于配制水可稀释的单组分环氧树脂体系。 通过添加水释放胺,并且可用于与环氧基团的固化反应。 在该系统的基础上配制的涂料的特征在于非常低的辅助溶剂含量。 固化的涂膜显示出优异的流平性和膜性能。
