Method of producing a curable epoxy resin composition

摘要

Curable epoxy resin composition comprising an epoxy resin component and a filler component and optionally a hardener component and further additives, wherein (a) said curable epoxy resin composition has been produced by separately mixing together at least a part of the epoxy resin component and at least a part of the filler component and optionally some or all of the optional additives, previously to mixing theses components with the optional hardener component and with any remaining optional additives present in the curable epoxy resin composition, and that (b) said mixing together of at least a part of the epoxy resin component and at least a part of the filler component and optionally some or all of the optional additives has been carried out at a temperature higher than the casting temperature of the curable epoxy resin composition, and electrical insulation systems made therefrom.
