Long pot life, rapid curing properties and low shrinkage properties to produce an aqueous epoxy curing agent used in the two dosage epoxy self-leveling compounds with compositions and methods

摘要

present invention includes at least one diprimary amine, at least one mono-primary amine may be obtained by reacting at least one polyepoxy compound, for epoxy resins a water-dilutable curing agent, the molar ratio of the primary amino group and an epoxy group in the reaction is from about 1.7: 1 to 1: 1, the primary during the diprimary amine and an amine, the ratio of the secondary amines optionally present in di-primary amine, 1: greater than 1, the molecular weight of the di-primary amine (Mw) of 500 daltons or less, water-dilutable curing agent on. These water-dilutable curing agent, indicates together with the epoxy resin excellent utility for the self-leveling applications, as compared to commercially available products, high compressive strength, low shrinkage, high impact resistance and high wear resistance It provides excellent final properties of the equal.BACKGROUND
