DELO offers special adhesive for automotive lighting applications
DELO offers special adhesive for automotive lighting applications. DELO 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.
With a high viscosity of 75,000 mPa·s, DELO PHOTOBOND OB4189 enables a high enough aspect ratio for the bonding process. The adhesive thus retains its shape after dispensing and does not flow, which is important for bonding microlens arrays. It is also extremely resistant to yellowing, as shown by life cycle simulations of 500 hours at 140 °C. This is essential for such optically demanding applications.
