Charged EVs | Axalta launches EV battery coatings for warmth safety and electrical insulation

Axalta has launched two new powder coatings—Alesta e-PRO FG Black and Alesta e-PRO Dielectric Grey—developed to deal with warmth administration and insulation necessities in EV battery purposes.

Alesta e-PRO FG Black is designed for thermal stability and secondary fireplace safety in EV battery methods. In line with Axalta, this coating resists ignition, enlargement, and smoke technology even throughout thermal occasions at temperatures as much as 1200°C. Technical options embrace the upkeep of thermal integrity underneath direct flame and excessive warmth (600–1200°C), zero smoke emission at excessive temperatures, and strong corrosion safety both standalone or over electrocoated substrates.

Alesta e-PRO Dielectric Grey is an epoxy-based powder coating chosen for its electrical insulation properties in high-voltage settings resembling EV battery packs and stationary power storage. It offers sturdy edge protection for electrical insulation, excessive yield in excessive potential (hipot) testing, flexibility for complicated geometries, and passes 6 kV hipot standards. The corporate says this product additionally demonstrates superior lap shear energy for structural reliability underneath utilized stress.

The Dielectric Grey coating has been evaluated for UL 94 V0 and IEC 60243-1 requirements, whereas FG Black has demonstrated efficiency underneath direct flame publicity, single-cell thermal runaway and UL 2596 TaG assessments. Throughout direct flame publicity at 1200°C, the FG Black coating produced no smoke and didn’t ignite, in accordance with the corporate.

“Our clients are searching for applied sciences that may stand up to excessive environments and help their efforts to construct secure and dependable battery methods,” stated Dr. Robert Roop, Senior Vice President and Chief Know-how Officer at Axalta. “These new coatings replicate our dedication to innovation and to partnering with clients to satisfy the challenges of next-generation mobility.”

A number of main unique gear producers and Tier 1 suppliers are at present conducting extra validation assessments primarily based on their design and pre-production approval processes.
