Abstract: An epoxy resin composition in an outdoor application and/or a high voltage application of an electrical insulation is described. The epoxy resin composition includes an aliphatic epoxy resin; and a catalyst system. The catalyst system is present in a content of 0.5-5 phr in the epoxy composition. The catalyst system includes at least one of the group consisting of: BX amine complex and blocked super acid. The epoxy resin composition is substantially anhydride-free. Further, a power product including insulation is described. The insulation includes a hydrophobic, cycloaliphatic epoxy resin; and a catalyst system. The catalyst system is present in a content of 0.5-5 phr in the epoxy composition. The catalyst system includes at least one of the group consisting of: BX amine complex and blocked super acid. The epoxy resin composition is substantially anhydride-free.
