An insulating tape comprising a tape adhesive including at least one tape accelerator in solution and/or in ultrafine divided form, wherein the at least one tape accelerator is selected from the group consisting of imidazoles, imidazole derivatives, pyrazoles, pyrazole derivatives and combinations thereof.
A coil of an electric motor/generator comprising windings, wherein at least one of the windings has an insulating tape with impregnation, wherein the insulating tape comprises at least one imidazole, at least one pyrazole, at least one imidazole derivative, or at least one pyrazole derivative as a curing agent, as a gelling agent or as a tape accelerator.
A method for gelling or curing phthalic anhydride-free epoxy resins based on bisphenol A and/or bisphenol F diglycidyl ether, the method comprising
- impregnating the resins with at least one curing or gelling agent selected from the group consisting of imidazoles, pyrazoles, imidazole derivatives, pyrazole derivatives, and combinations thereof.
