  • Patent number: 5942563
    Abstract: An aqueous protective coating composition particularly useful for can coatings is based on a polymeric binder comprising epoxy crosslinked microgel particles. The microgel polymer is produced by dispersing into water a carboxyl functional, acrylic-epoxy grafted copolymer, and combined with a high molecular weight, branched, multifunctional epoxide resin, followed by coreaction and crosslinking between the carboxyl copolymer and branched epoxide to form stable aqueous dispersed microgel particles. In a preferred aspect of the invention, low molecular weight liquid diepoxide is dispersed into and crosslinked with the carboxyl functional acrylic grafted epoxy copolymer.

  • Patent number: 5854312
    Abstract: Described are aqueous emulsions of active amino groups-displaying epoxide adduct hardeners for curing epoxy resin systems, which are obtained by converting an aqueous solution of a conventional hardener, which contains reactive amino groups and can emulsify the epoxy resin used for adduct formation, under increase of the amine-H-equivalent weight, to an emulsion by mixing with an epoxy resin having a functionality of 1,2-3,5. The viscosity generally is 5 to 40 Pa.s. The values lie on an emulsion viscosity curve with a rising and falling viscosity profile. The hardeners are especially suitable for curing aqueous epoxy resin systems and for application together with epoxy resins as additive for hydraulic binders such as cement.
