The colloidal aspects of formulating two-part ambient cured waterborne epoxy paints which utilize so-called self-emulsifying technology (liquid epoxy resin plus water-thinnable hardener) are discussed. Experimental data are presented for commercial amine-type water-thinnable hardeners on dilution behavior, co-emulsification with liquid epoxy resins, and performance of paint compositions. Approaches are offered for the selection of key components and some additives (in particular, of co-sol-vents and co-emulsifiers) for epoxy waterborne film forming compositions.
