ABSTRACT:
The invention relates to epoxy resin hardener compositions containing at least one mercaptan hardener and at least one metal salt of C8-24carboxylic acids. These hardeners are distinguished in particular by the fact that catalyzed resins containing epoxy resins and the hardener compositions according to the invention give high-gloss molding compounds, more particularly coatings, after hardening by crosslinking.
