ABSTRACT:
An aqueous multi-component epoxy coating composition having less than 3% by weight of VOCs and curable upon admixing the components comprises (a) a first component of (i) a stable epoxy dispersion of an epoxy resin, from 5 to 20 weight percent of a mixture of surfactants comprising a low temperature nonionic surfactant having a molecular weight of from 1,000 to 7,000; a high temperature nonionic surfactant having a molecular weight of greater than 7,000 to 20,000 and an anionic surfactant, and (b) a second component of (i) a water miscible polyamine, wherein the composition further contains an associative thickener as well as thixotropic clay and/or a cellulosic thickener as additional thickener(s).
