摘要：
The present invention relates to an aqueous epoxy resin blend dispersion of a high mw epoxy resin and a liquid epoxy resin with a dispersant having an interfacial tension such that a drop of the mixture of the dispersant in a melt of the epoxy resin blend against water is less than 2 dynes/cm, preferably less than 1 dyne/cm, and a process for preparing this epoxy resin blend dispersion. Specifically, the process is a solvent free melt kneading or shearing dispersion process wherein the dispersion is processed at from 50 to 150° C., and the resulting dispersion is stable.
