    • Stable aqueous emulsions of epoxy resins are provided using an epoxy-functional surfactant prepared by reacting an amidoamine having the formula: wherein R1 is an alkyl, aryl, or arylalkyl group or mixtures thereof having 1 to 15 carbon atoms, R2 is aliphatic, cycloaliphatic, or aromatic group having 2 to 18 carbon atoms optionally containing non-reactive oxygen or at most all average of 4 secondary and/or tertiary nitrogen atoms per structure in the backbone, X and Y are independently a hydrogen, methyl or ethyl group with the provision that if X is methyl or ethyl, Y is hydrogen or if Y is methyl or ethyl, X is hydrogen, and n+m+o is a real number from 40 to 400, and n+o is a real number in an amount effective to provide resin emulsification, and the ratio of (I) to (II) by weight. is in the range of 100:0 to 0:100, the ratio of (I) to (III) by weight in the range of 100:0 to 0:100, and the ratio of (II) to (III) by weight in the range of 100:0 to 0:100, and at least one epoxy resin having a functionality of from greater than 0.8 epoxide group per molecule in an amine to epoxy equivalent ratio of at least 1:2.
    • 使用环氧官能表面活性剂提供稳定的环氧树脂水性乳液,该表面活性剂通过使具有下式的酰氨基胺反应制备:其中R1是烷基,芳基或芳烷基或其具有1至15个碳原子的混合物,R2是脂族,脂环族, 或任选地含有非活性氧的碳原子数为2〜18的芳族基团,或者骨架中每个结构最多具有4个仲和/或叔氮原子的平均值,X和Y独立地为氢,甲基或乙基, 如果X是甲基或乙基,Y是氢或Y是甲基或乙基,X是氢,n + m + o是从40到400的实数,n + o是有效量的实数 提供树脂乳化,以及(I)与(II)的重量比。 在100:0至0:100的范围内,(I)至(III)的重量比在100:0至0:100的范围内,(II)与(III)的重量比 在100:0至0:100的范围内,以及至少一种具有至少1:2的胺/环氧当量比的每分子具有大于0.8个环氧基的官能度的环氧树脂。
