    摘要: A curing agent for aqueous epoxy resin emulsions is described, which curing agent contains 10-80% by weight of at least one emulsifier, 1-80% by weight of at least one coemulsifier, and 5-80% by weight of at least one bis(diamine)-diepoxide adduct. Optionally, the curing agent furthermore contains 0-80% by weight of a diamine or a mixture of two or more diamines. Said curing agent has the ability of forming microemulsions when water is added, preferably non-ionic oil-in-water microemulsions. Said microemulsions have a good shelf life. They are useful as curing agent for any desired aqueous epoxy resin dispersions, and they can also be used as curing agent in compositions based on epoxy resin and cement mortar.

    摘要: Resistance to thermal shock of certain anhydride cured epoxy resins is unexpectedly enhanced by addition of certain polyether diamide additives. This superior resistance does not appreciably compromise heat deflection properties. The resins comprise a vicinal polyepoxide, a curing amount of certain bicyclic anhydride and an effective amount of a polyether diamide having terminal amido groups and a molecular weight of from about 2000 to about 3000.
