Radiator Coating of New Energy Vehicles Uses Silicon Carbide
As New Energy Vehicles (NEVs) evolve toward higher power densities and faster charging capabilities, traditional cooling solutions are reaching their physical limits. Green Silicon Carbide (SiC) Micro Powder has emerged as the premier filler for high-performance radiator coatings due to its exceptional physical properties:
- Ultra-High Thermal Conductivity: With a theoretical thermal conductivity far exceeding alumina, SiC micro powder transforms protective coatings into active heat-dissipation layers, significantly reducing interfacial thermal resistance.
- Superior Electrical Insulation: Engineered SiC micro powder provides the critical dielectric strength required for EV battery cooling systems and electronic control units, ensuring safety alongside cooling.
- Low Coefficient of Thermal Expansion (CTE): Its minimal CTE ensures excellent adhesion and prevents coating delamination or cracking during extreme thermal cycling—a must for long-term vehicle reliability.
- Extreme Hardness and Corrosion Resistance: Boasting a Mohs hardness of 9.5, it provides a robust shield against stone chipping, road salt, and environmental corrosion, extending the service life of aluminum radiator cores.
