A process for producing stable dispersions of epoxy resins is presented in which an epoxy resin is mixed with water in the presence of a reactive surfactant to form a predispersed resin. To this predispersed resin, a micronized dicyandiamide based curing agent is added to form a predispersed resinous mass. The mass is stirred for a time and at a temperature sufficient to convert the predispersed resinous mass to a stable epoxy resin dispersion where the water is the continuous phase and the resin is the dispersed phase. The dispersion is useful as a one-pack epoxy resin system in applications such as binders for non-wovens, papers, textiles, composites, and laminates and in many coating applications. |
