Abstract

The present invention relates to a catalyst composition for curing resins containing epoxy groups, in particular epoxy/polyurethane hybrid resins, the catalyst composition containing an imidazolium salt, in addition to a base, as well as a method for curing such resins in the presence of the catalyst composition, to the use of the catalyst composition for curing resins containing epoxy groups, to resin systems comprising a resin containing epoxy groups and the catalyst composition, and to a dosing system that comprises the resin and the catalyst composition.
