Solderable Polyesterimide Wire Enamels (PEI)

Solderable polyesterimide wire enamels are widely used on magnet wires for relays, small transformers, small motors, contactors, ignition coils, magnetic coils and automotive coils.

The Voltatex 7200 series, one of Axalta’s polyesterimide wire enamels, allows solderability at temperatures above 450°C. These coatings are particularly well-suited in small electrical motors to connect the windings to the collector. The coated magnet wires have good elasticity as well as good dielectric and mechanical properties.
