Market Overview

Fire-resistant and intumescent coatings used in EVs and energy storage systems are engineered materials that expand, char, or insulate when exposed to high temperatures, thereby delaying heat transfer and structural failure. These coatings are applied to battery enclosures, module frames, pack covers, and adjacent structural elements to prevent or slow thermal runaway propagation. Unlike traditional fireproofing, EV-focused coatings must combine high fire resistance with low weight, thin-film performance, and compatibility with metals, composites, and polymers.

Performance requirements include resistance to jet flames, high heat flux, and prolonged exposure. Adoption is driven by OEM safety strategies, regulatory standards, and insurance requirements. The market serves EV OEMs, battery manufacturers, ESS integrators, and tier-1 suppliers.
