Axalta Coating Systems Ltd, a global coatings company will unveil two products at The Battery Show North America (Booth #1638).
The new products, Alesta e-PRO FG Black and Alesta e-PRO Dielectric Gray, which are part of Axalta’s broad portfolio of battery coatings, have been engineered for extreme heat protection and better electrical insulation in EV battery applications.
Dr. Robert Roop, Senior Vice President and Chief Technology Officer at Axalta explained: “While electric vehicles are statistically far less likely to catch fire than gasoline-powered vehicles, high-profile incidents and misinformation continue to impact public perception.
“These breakthrough products demonstrate the amazing power of coatings to rise to new challenges and reflect Axalta’s proven history of innovating products that impact the world for the better.”
Even as electric vehicles are growing in popularity, concerns remain among consumers about their safety, specifically around batteries.
Thermal runaway in EV batteries remains a rare yet serious risk that can lead to fires, explosions and structural failure.
When one battery cell overheats, it can trigger a chain reaction, rapidly releasing extreme heat, flames and smoke at temperatures exceeding 1200°C.
When applied as part of a validated OEM battery system, these new coatings may contribute to improved thermal stability and electrical insulation performance.
Alesta e-PRO FG Black is a powder coating engineered for thermal stability and secondary fire protection in electric vehicle battery systems.
This coating is designed to resist ignition, expansion and smoke generation at extreme temperatures up to 1200°C, helping to delay fire propagation from thermal events.
Key design features include:
Alesta e-PRO Dielectric Gray is an epoxy-based powder coating designed to provide robust electrical insulation in high-voltage environments such as electric vehicle battery packs and stationary energy storage systems.
This coating delivers excellent hipot test yield, improving reliability.
Key design features include:
Alesta e-PRO products have undergone rigorous testing for electrical insulation and thermal protection.
The Dielectric Gray has been tested for UL 94 V0 and IEC 60243-1 amongst several others. The FG Black product has been tested for direct flame exposure, single-cell thermal runaway and UL 2596 TaG tests.
When exposed to direct flame at 1200°C, Axalta’s Alesta e-PRO FG Black produces no smoke and does not catch fire during thermal events.
Dr. Roop continued: “Our customers are looking for technologies that can withstand extreme environments and support their efforts to build safe and reliable battery systems.
“These new coatings reflect our commitment to innovation and to partnering with customers to meet the challenges of next-generation mobility.”
The coatings are designed for global automotive manufacturers producing EVs, with the global EV market on track to surpass 20 million units in 2025, accounting for over a quarter of cars sold worldwide.
Several leading OEMs and Tier 1 suppliers are currently conducting additional testing based on their specific designs and pre-production part approval processes.
