ABSTRACT:
Aqueous compositions suitable for sanitary can coatings comprising the neutralized water dispersible ionic polymer product of the reaction of an epoxy resin with acid polymer, and a different resin which is not necessarily self-dispersible in water, as well as several methods of preparing such compositions, are disclosed. The second resin which is not necessarily self-dispersible in water is introduced either preformed at any stage or is prepared, in situ, in the presence of the epoxy resin esterified with acid polymer either before the ionic epoxy resin-acid polymer product is dispersed in water. The epoxy resin-acid polymer product acts as a polymeric surfactant capable of keeping even a normally non self-dispersible second polymer in stable dispersion in water.
