Polyamide-imide Wire Enamels (PAI)

Polyamide-imide wire enamels can be used either as dual or single coat, but both options deliver excellent mechanical properties and chemical resistance. In addition to the classical polyamide-imide overcoat, Axalta provides a wire enamel with integrated lubricants for increased winding speed. These products are specifically used to coat wires in electrical motors, refrigeration equipment, transformer windings and ballasts for fluorescent lamps. For flat wire applications, big transformers and generators, Voltatex 8300 series, based on polyamide-imide, is recommended. It can be used as a flexible top coat in combination with a polyester or polyesterimide base coat to improve the mechanical, chemical and thermal properties of the coating. In certain circumstances, Voltatex 8300 series can also be applied as a single coat for flat wire applications.
