Huntsman, one of the leading global companies in polyurethane-based solutions, has launched a new intumescent polyurethane coating system developed for automotive applications, which can provide passive fire protection to metal and composite substrates used in electric vehicles (EVs) – without compromising design flexibility.

POLYRESYST EV5005 polyurethane coating system has been developed to help protect structural integrity and improve fire protection in battery cells – a key challenge in the automotive industry.

The launch of the new coating technology coincides with EV manufacturers intensifying their efforts to enhance fire safety – driven by regulatory changes, technological advancements and heightened consumer awareness. The new system will be unveiled at The Battery Show Europe in June and promoted alongside Huntsman’s wider portfolio of polyurethane systems for EV manufacturers.

Irina Bolshakova, Global Automotive Marketing Director at Huntsman, said: “The use of technologies that can help delay or prevent thermal runaway is a hot topic in the automotive industry. Manufacturers are actively looking for materials that enable them to integrate additional fire resistance into battery enclosures and other interior components, without adding weight or complexity to the design and manufacture of vehicles. POLYRESYST® EV5005 system has been developed with exactly those needs in mind and is part of a wider portfolio of products that we offer to help safeguard the structural integrity of EV batteries.”

Huntsman’s new intumescent coating complements the other polyurethane-based solutions the business has developed for EV battery applications
