Abstract
A hardener component is useful for a multi-component epoxy resin material, and includes a benzoxazine amine adduct as an accelerator and an amine as a hardener. The benzoxazine amine adduct is present in the hardener component in a proportion of from 8.5 wt. % to 75 wt. %. The multi-component material including the benzoxazine amine adduct in the hardener component already has a quick curing time at room temperature and can therefore be used advantageously for the chemical fastening of construction elements.
