Abstract

Essentially, solvent-free, stable aqueous dispersions or low solvent emulsions of epoxy resins are made through use of selected nonionic surfactants and selected organic solvents followed by vacuum distillation of most or almost all of the organic medium. The stable aqueous emulsions are useful for making coatings, films and the like.
