Abstract
The present invention concerns a low-odor, low-viscosity hardener for epoxy resins comprising the amine of formula (I),as well as a method for thinning of hardeners for epoxy resins by adding the amine of formula (I). These hardeners harden with epoxy resins quickly and without blushing to form films of high hardness and little brittleness, even without non-incorporable thinners such as benzyl alcohol. They are especially suitable for low-emission coatings.
