    • An epoxy or hardener mixture comprising (a) optionally water, (b) at least one hardener or epoxy resin, and (c) from 0.1 to 20 weight percent, based on epoxy resin of at least one distyryl phenol, tristyryl phenol or cumylphenol based additive surfactant with phosphate or sulfonate end groups having the structure R—OXn-W wherein R designates a polystyrylphenol or cumylphenol, preferentially chosen from among distyrylphenol, tristyrylphenol or cumylphenol, and mixtures thereof, and wherein OX designates ethylene oxide and/or propylene oxide. The number of groups “n” varies from 0 to 200, and W designates H, sulfate (—SO3−) or phosphate (—PO3H or —PO2—OXnR). Freeze thaw resistance and improved stability is obtained in epoxy mixtures used in dispersion form. Improved pot life and cure time is obtained using either the epoxy mixture, the hardener mixture or a combination of the two in epoxy hardener formulations.
    • 一种环氧树脂或硬化剂混合物,其包含(a)任选的水,(b)至少一种硬化剂或环氧树脂,和(c)基于至少一种二苯乙烯基苯酚的环氧树脂,三苯乙烯基苯酚或枯基苯酚基的0.1-20重量% 具有R-OXn-W结构的磷酸酯或磺酸酯端基的添加剂表面活性剂,其中R表示聚苯乙烯基苯酚或异丙苯酚,优选选自二苯乙烯基苯酚,三苯乙烯基苯酚或枯基苯酚,及其混合物,其中OX表示环氧乙烷和/或环氧丙烷。 基团“n”的数目为0至200,W表示H,硫酸根(-SO 3 - )或磷酸根(-PO 3 H或-PO 2 -O X n R)。 在分散形式使用的环氧树脂混合物中可获得抗冻融性和稳定性。 使用环氧混合物,硬化剂混合物或两者在环氧固化剂配方中的组合来获得改善的适用期和固化时间。
