Abstract
The invention relates to hardeners for epoxy resin containing secondary amino groups having dialkyl amino phenyl groups. The hardeners have a surprisingly low viscosity and harden surprisingly fast together with the epoxy resins, even in moist, cold conditions, and without blushing to form films with high hardness and stability. They are suitable, in particular, for low-emission coatings.
