With DELO DUALBOND OB6799, DELO is launching an adhesive that has been optimised to meet the high optical requirements of modern driver assistance systems. With it, the adhesive manufacturer is setting new process speed and alignment accuracy standards for automotive cameras.
Advanced Driver Assistance Systems (ADAS) such as lane departure warning and emergency braking systems are becoming increasingly capable, steadily improving vehicle safety. LiDAR and RADAR sensors, as well as high-resolution cameras, are essential to these systems.
A product specifically designed for bonding and active alignment of ADAS cameras is DELO DUALBOND OB6799. The epoxy adhesive has a linear curing shrinkage that is reproducibly below 1%. In addition, the product exhibits low swelling behaviour, even under changing temperature and humidity conditions, so that camera focus remains optimally adjusted and can permanently fulfil its safety functions.
Since high-resolution cameras are primarily made of aluminium, the coefficient of thermal expansion (CTE) was specially adapted to this material. DELO highlights that application-relevant aging tests confirm the adhesive’s high bonding strength to aluminium substrates.
Due to the adhesive's rapid light fixation, the aligned components are precisely fixed within a few seconds and, from that point, reliably maintain their position – making DELO DUALBOND OB6799 ideal for high volume manufacturing processes. The final curing of the adhesive takes place via low heat at +80°C.
