UV curing adhesive Photolec A
Mobility
-Challenge- Moisture intrusion into the camera module
There are various sensors used in advanced driver assistance systems (ADAS), and in-vehicle cameras are one of the main sensors used in ADAS.
The technical challenges for the lens unit of camera modules include shortening of the curing time when attaching the lens, improvement of bonding strength, water entering the unit, and the light passing through the adhesive.
-Solution- UV fast-curing adhesive with excellent sealing reliability
The UV-curing adhesive Photolec A is a UV-curing high-transparency adhesive ideal for attaching optical devices.
It cures quickly with UV light even when exposed to oxygen.
It has excellent adhesion to glass and securely holds lenses in place.
High resistance to water and excellent sealing reliability, preventing water from entering the module.
It can be made black (the black variant is also curable by UV irradiation), preventing light from passing through the adhesive around the lens.
