Abstract
An amine of the formula (I) for use as hardener for epoxy resins, hardeners for epoxy resins containing the amine of the formula (I) and resultant epoxy resin compositions which more particularly can be used as low-emission room-temperature-curing epoxy-resin coatings with high hardness and surface quality. The amine of the formula (I) has little odor and is a very successful diluent for epoxy resin compositions. It is more particularly obtained by reductive alkylation from 1,2-propylenediamine and an aldehyde or ketone.
