High-Temperature Coatings Scale With EV Motor Production
Electric vehicle motor manufacturers are increasingly specifying high-temperature coating formulations capable of surviving the thermal cycling and mechanical stress inherent to high-speed traction motor operation, a meaningfully different requirement than traditional transformer-grade coatings. Nippon Steel and JFE Steel have both expanded dedicated high-temperature formulation capacity over the past two years specifically to serve this growing motor lamination demand. At least a dozen major automotive motor programs have adopted high-temperature coating specifications since 2023, and producers report these specialized formulations now command meaningfully higher per-kilogram pricing than standard transformer-grade coatings. Automakers weigh this documentation heavily when selecting suppliers.
