Huntsman launches intumescent polyurethane coating system for EV battery

Huntsman 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.

The new intumescent polyurethane coating system is developed for EV battery protection.

 

POLYRESYST EV5005 polyurethane system has been developed to be spray applied without any thickness constraints to help meet the fire standards needed.

 

The material is fast curing and has high mechanical strength with hydrolytic stability and abrasion resistance, delivering a tough yet flexible layer that can help improve the structural integrity of core components in the event of impact or a thermal event.

 

Developed for use on automated manufacturing lines, POLYRESYST EV5005 system can also help manufacturers save time. The technology adheres well to different substrates and is fast setting, hardening in seconds, without the need for oven or post curing. A short tack-free time also means additional coats can be built up quickly as required and the sprayed substrates can be moved quickly after coating.

 

The new system will be unveiled at The Battery Show Europe on June 3-5 in Stuttgart, Germany, and promoted alongside Huntsman’s wider portfolio of polyurethane systems for EV manufacturers.
