Innovative film technology that allows automotive manufacturers to hide radar sensors behind decorative metallic parts has been developed by AkzoNobel.

The radar-transparent bright film means vehicle makers no longer have to worry about hiding sensors behind solid metal, which can block the signals of safety features such as anti-collision warnings.

“Vehicle requirements are changing all the time.

“We’re very happy to have solved this difficult problem with an intelligent film coating that allows radar signals to pass through,” explains Patrick Bourguignon, Director of AkzoNobel’s Automotive and Specialty Coatings business.

“It was a highly technical process. Involving a close collaboration with customers, to establish correlations between film properties and radar transmission,” he continues.

“Innovation not only drives our business. It also contributes to the success of our customers,” says Bourguignon.

He also adds that other vehicle manufacturers are keen to include the bright film technology in their designs.
