  • Method of preparation of a water based epoxy curing agent
    Patent number: 7615584
    Abstract: The present invention relates to a method of preparation of a water based epoxy resin curing agent in dispersion form which is formed by combining an amine-functional dispersion (A) with an amine-functional curing agent (B). The invention also relates to the curing agent obtained from said method, its use for curing two component water based epoxy systems, compositions obtained from such curing and various uses of the compositions obtained.

  • Aqueous hardeners for epoxy resin systems
    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.
