In a two-pot casting process for cured mouldings, an acid anhydride curing agent/filler composition on the one hand and an epoxy resin/accelerator composition on the other hand are prepared. The accelerator used is a quaternary onium salt. In order to prevent migration of the charge carriers present in the accelerator, the accelerator also contains groups which are reactive with the epoxy resin/acid anhydride curing agent mixture. These groups cause fixing of the accelerator in the network formed during curing.
