Voltatex® 7433 is specially designed preferably for the enamelling of rectangular but also of heavy round conductors. Magnet wires insulated with Voltatex 7433 have excellent mechanical properties. In order to achieve increased resistance to chemicals, an application combined with polyamideimide based topcoat (e.g. Voltatex 83.. or Voltatex 85..) is needed. Magnet wires coated with Voltatex 7433 exceed the requirements and technical conditions of IEC 60317-29. Listed test results based on Axalta Coating Systems standards, following IEC standards 60851.
