German firm launches EV battery coatings for 2,192°F heat protection

German company Axalta Coating Systems has introduced two new coatings—Alesta e-PRO FG Black and Alesta e-PRO Dielectric Gray—aimed at enhancing safety and performance in electric vehicle (EV) batteries. Unveiled at The Battery Show North America, these coatings address the critical issue of battery safety, particularly the risk of thermal runaway, where overheating of one battery cell can trigger a chain reaction causing extreme heat and fire. Alesta e-PRO FG Black offers high thermal stability and secondary fire protection, maintaining integrity under direct flames and temperatures up to 1200°C (2,192°F), while also providing corrosion resistance and zero smoke emission. It has passed rigorous testing, including UL 2596 TaG, to help delay fire propagation in EV battery systems. The Alesta e-PRO Dielectric Gray coating focuses on electrical insulation, featuring high dielectric strength, flexibility, and consistent edge coverage suitable for complex battery pack designs. It meets UL 94 V0 and IEC
