DELO has developed a new adhesive for automotive lighting applications. Photobond OB4189 is resistant to yellowing and, with its high aspect ratio, is particularly suitable for bonding microlens arrays, such as those found in headlights and projection systems.
These days, light is considered among the most important elements of automotive design and differentiation. Microlens arrays are a key player in these developments. They project LED light, which sits behind a very short focal length, providing sharp images and individual geometries. These systems are increasingly being used as optics in headlights and projection systems due to their low required installation depth.
