Abstract
A curing agent for epoxy resins, containing at least one amine adduct of formula (I) which can be obtained as an addition product of a mixture of a primary diamine, a monoalkylated other diamine and a polyepoxide. The curing agent makes it possible to produce low-odor, low-emission epoxy resin products, in particular coatings, which have a surprisingly low viscosity, a high curing rate, a high final hardness, and a surprisingly appealing surface.
