Abstract
Stable aqueous emulsions of epoxy resins containing as an emulsifying agent between 2 and 10% by weight relative to the weight of the epoxy resin of ethylene oxidepropylene oxide block polymers having the formulae R--O--CH(CH.sub.3 CH--O ].sub.X [CH.sub.2 CH.sub.2 --O ].sub.Y H and R--O--CH.sub.2 CH.sub.2 (CH.sub.3)--O ].sub.X [CH.sub.2 CH.sub.2 --O ].sub.Y H in which X is an integer of at least 8 and at most 22, Y is an integer from at least 25 and at most 40, and R is a radical of the group consisting of alkenyl, aralkyl, cycloalkyl, aralkenyl and cycloalkenyl radicals.
Claims6
A stable aqueous emulsion of an epoxy resin, said emulsion containing, as an emulsifying agent, between 2 and 10% by weight relative to the weight of the epoxy resin, of an ethylene oxide-propylene oxide block copolymer having the formulae:
- R--O--CH(CH.sub.3)CH--O].sub.X [CH.sub.2 CH.sub.2 --O].sub.Y H
- and
- R--O--CH.sub.2 CH.sub.2 (CH.sub.3)--O].sub.X [CH.sub.2 CH.sub.2 --O].sub.Y H
- in which formulae X is an integer of at least 8 and at most 22, Y is an integer of at least 25 and at most 40, and R is a radical selected from the group consisting of alkenyl, aralkyl, cycloalkyl, aralkenyl and cycloalkenyl radicals.
