Abstract
Stable epoxy dispersion compositions are prepared by emulsifying in water a self-emulsifying epoxy resin film forming component which is the reaction product of (a) a diglycidyl ether of a dihydric phenol, (b) a dihydric phenol and (c) a diglycidyl ether of a polyoxyalkylene glycol. The stable dispersions can be modified by the addition of an aliphatic monoepoxide reactive diluent to the dispersion. The epoxy dispersion compositions when combined with epoxy resin curing agents are useful as coating compositions.
