AbstractComposition for use in making electrical insulating products such as transformer bushings comprises a mixture of cycloaliphatic epoxy resin, an anhydride curing agent, and a filler material including zirconium silicate and hydrated alumina. To provide for increased pot life of the material, the epoxy resin and a portion of the filler material are stored in one heated vessel while the anhydride curing agent and the remaining filler material are held in a separate heated vessel, the two components being mixed together prior to pouring the material into the product mold.
