Beschreibung
Zusammenfassung:	Various embodiments of the teachings herein include a solid insulation material based on a resin containing epoxy groups for production of an anhydride-free insulation system by means of VPI. The material comprises: an anhydride-free curing catalyst; and an additive for improving distribution of the anhydride-free curing catalyst, wherein the additive comprises a phenyl carboxylate. The additive is present in an amount based on the epoxy groups in the resin containing epoxy groups which is present in the impregnating agent of at least 0.1% in stoichiometric terms.
