How can cutting edge dual cure epoxy adhesives redefine optical precision, electrostatic stability, and long term reliability in ADAS sensor modules?
✨ Market Trends: The automotive industry’s migration toward autonomous driving requires adhesives with engineered dielectric strength, high glass transition temperatures, and robust resistance against thermal cycling, moisture ingress, and electrostatic discharge—parameters critical for safe operation of advanced optical and electronic assemblies.
✨ Applications: LOCTITE® ABLESTIK NCA 3218 is specifically formulated for ADAS optical modules, ensuring secure bonding in lens barrel to housing and lens housing to circuit board interfaces where dimensional accuracy and dielectric integrity are non negotiable.
✨ Highlights: This 1 component UV cationic thermal dual cure epoxy delivers fast UV curing with low volumetric shrinkage (≈1.4%), high Tg of 215 °C, low coefficient of thermal expansion, and excellent adhesion to substrates such as FR4, aluminium, and high performance plastics (PBT, PPS). Its intrinsic grey pigmentation prevents stray light penetration, enhancing optical fidelity in sensor systems.
✨ Product Advantage: Unlike conventional acrylate adhesives, LOCTITE® ABLESTIK NCA 3218 ensures nanometer level dimensional stability, superior electro mechanical endurance under vibration and humidity, and REACH compliant formulation free from CMR, SVHC, and antimony. This positions it as a benchmark adhesive for electronics, optics, and paint coated module assemblies where performance, safety, and sustainability converge.
