DELO launches active calibration adhesive for high-resolution automotive cameras

Advanced driver assistance systems (ADAS) such as lane departure warning and emergency braking systems are becoming more and more powerful, steadily improving vehicle safety. Lidar, radio radar sensors and high-resolution cameras play a crucial role here.

DELO has launched an optimized adhesive, DELO DUALBOND OB6799, which meets the high-performance requirements for optical components in modern driver assistance systems. With this product, DELO
In automotive camera production, process speed and accuracy standards are raised to new heights.

DELO DUALBOND OB6799 has been specially developed for bonding and active calibration of ADAS cameras. This epoxy resin adhesive has less than
Stable linear shrinkage of 1%. The product exhibits extremely low expansion even under changing conditions of temperature and humidity, allowing the camera to maintain optimal focus and ensure long-term stability of its security functions.

Since the main base material of high-resolution cameras is aluminum, DELO specifically adjusts the coefficient of thermal expansion (CTE) for this type of material. For example at +85 °C temperature, 85 %
Storage at relative humidity for 2,000 hours and application-related aging tests demonstrated the adhesive’s extremely high bonding strength to aluminum substrates.

Active calibration processes have been widely used in the automotive industry to manufacture high-precision optical sensor systems such as ADAS cameras, by actively reading image sensor data to determine the optimal alignment of the sensor and optics.

Thanks to the rapid photo-prefixing process of the adhesive, the aligned parts are precisely fixed and remain in their corresponding positions within seconds. The adhesive is capable of final curing at temperatures as low as +80 °C. Therefore DELO
DUALBOND OB6799 is particularly suitable for mass production that has strict requirements on production efficiency and alignment accuracy.
