DELO has created DELO PHOTOBOND UV acrylates for optoelectronics that allow fast and true-colour bonding of holographic films manufactured by Covestro. The automotive industry and many others will profit from rapid roll-to-roll manufacturing and sounder integration of the films into holographic end-use applications.
AR-HUDs portray one of the most critical future applications for holographic films, like Bayfol HX from Covestro. As these films are incorporated into the windshield, projections merge with reality so that the navigation appears to be displayed directly on the road. The films provide for brighter and larger images while decreasing installation space.
This holographic film technology also provides design freedom and smaller space needs in the rear lights of cars and other automotive lighting applications. Customised holograms, such as a warning message that says 'Stop' in the driver's field of vision, can be created to increase safety.
No matter the application, holographic films are thin, lightweight and totally invisible under so-called off-bragg conditions – whenever the coupled light does not satisfy specific needs, such as the correct wavelength. The films normally comprise RGB-sensitive photopolymers on a transparent carrier film and are embedded between two protective cover layers.
"Our holographic films have the potential to push the existing boundaries of automotive lighting capabilities," says Richard Meisenheimer, Application Development Holographic LightGuiding at Covestro. "With UV adhesives, DELO gives our customers another manufacturing option and helps them process the products in their application."
