Enabling the automotive vision of autonomous driving

Loctite Ablestik NCA 3218 delivers superior performance for lens bonding in ADAS sensors

Henkel has launched an innovative new dual cure adhesive specifically designed for bonding applications in automotive ADAS cameras and LiDAR modules. Using a unique UV cationic thermal dual cure epoxy, Loctite Ablestik NCA 3218 offers an ideal solution for applications such as lens barrel-to-housing and lens housing-to-circuit board bonding.

“Today’s advanced driver assistance systems (ADAS) are enabling a fundamental shift towards safer driving that seamlessly supports driver ability with high-resolution sensors and broad data base,” comments Michael Cai, ADAS Business Development Manager at Henkel. “As ADAS becomes an integral part of the modern driving experience – and a required feature of safety rating systems – automotive suppliers and OEMs are still seeking the optimal balance of manufacturing efficiency and the dependable performance demanded by safety critical applications. As a longstanding partner to the automotive industry, Henkel is pioneering new materials and processes to meet these challenges. Loctite Ablestik NCA 3218 demonstrates this commitment with a material that is optimised for the highly demanding area of ADAS sensors.”

Loctite Ablestik NCA 3218 is a dispensable, 1-component dual cure non-conductive adhesive. Due to its high glass transition temperature (Tg), the interface is less stressed, offering excellent adhesion to PCB, various plastics (PBT, PPS) and aluminium substrates. It has a low coefficient of thermal expansion (CTE), with a low and consistent cure shrinkage that minimises size change once cured. Loctite Ablestik NCA 3218 enables long-term robust and reliable performance throughout the entire lifetime of ADAS sensors. Its grey colour is also ideal for optical applications, as it ensures optimal blocking to prevent unintentional light penetration, providing additional quality assurance for the sensor.

Loctite Ablestik NCA 3218 has been created to meet global product safety standards and is CMR, SVHC, antimony free, and REACH compliant.
