Application Areas
To meet the protection requirements of the three-electric systems of new energy vehicles, this insulation powder coating has been specially developed to provide long-term protection for electric vehicle components. As the core power system of new energy vehicles, the three-electric system directly determines vehicle performance. Many components in the three-electric system operate under harsh environments involving high temperature and high voltage for long periods, requiring extremely high performance from protective coatings in terms of insulation, heat resistance, chemical resistance, and mechanical damage resistance.
Suitable for applications requiring insulation protection, including electrical cabinets, batteries, electronic control systems, motors, wiring harnesses, and other components.
