  • Process for obtaining aqueous compositions comprising curing epoxy agents
    Patent number: 7781499
    Abstract: A process for obtaining aqueous compositions including curing epoxy agents includes providing an aqueous mixture comprising at least one polymercaptan, at least one di- or poly(amido)amine, and water, and reacting the aqueous mixture with an uncured epoxy resin to form a final cured epoxy resin is provided. A process for obtaining aqueous compositions including curing epoxy agents includes providing an aqueous mixture of at least one waterpoxy treated with at least one polymercaptan, and reacting the aqueous mixture with an uncured epoxy resin to form the final cured epoxy resin is also provided.
