Estimating the term…
A self-dispersing curable epoxy composition is prepared upon contacting an epoxy resin with a polyoxyalkyleneamine having a molecular weight of from about 3,000 to about 15,000 in a ratio of about 0.001 to 0.060 reactive equivalents of polyoxyalkyleneamine to about 1.0 reactive equivalents of epoxy resin. The self-dispersing curable epoxy resin forms an aqueous dispersion upon mixing with water. When cured, the dispersion is useful as a coating composition.
A self-dispersing curable epoxy resin composition comprising the addition product of reactants comprising an epoxy resin and a polyoxyalkylene monoamine having a number average molecular weight of from about 3,000 to about 15,000 in a ratio of about 0.001 to 0.060 reactive equivalents of polyoxyalkylene monoamine to about 1.0 reactive equivalent of epoxy resin.
The method of making a self-dispersing aqueous epoxy resin composition comprising reacting (a) an epoxy resin with (b) a polyoxyalkylene monoamine having a number average molecular weight of from about 3,000 to about 15,000 in a ratio of about 0.001 to 0.060 reactive equivalents of polyoxyalkylene monoamine to about 1.0 reactive equivalents of epoxy resin to form a self-dispersing epoxy resin and dispersing the self-dispersing epoxy resin on a liquid comprising water.
