Adhesives for cameras and LiDAR

Adhesives play a particularly important role in cameras. Among other, they are used for traffic sign recognition, lane keeping, and collision warning assist systems even in mid-range cars. In this case, and also for the increasingly common LiDAR sensors in the luxury range, the bonded components including lenses, filters and image sensors, must function reliably in the long term. Low outgassing and low and reproducible shrinkage of the adhesive are crucial to this prerequisite. Even more important for the optics is that the lens position does not change after production. Users can use light-fixable adhesives to ensure this. The optics of the camera modules can thus be actively aligned and "frozen". Further processing without the lens slipping is therefore guaranteed. During the subsequent heat curing, the adhesive receives its final properties.

DELO has an extensive portfolio of adhesives with different chemistries to provide optimum solutions for the various bonding areas and material combinations for cameras and LiDAR sensors. They fulfill all optical and mechanical requirements even in the most adverse conditions, from direct sunlight under the windshield to outdoors with seasonally fluctuating temperatures, as well as rain, snow, and ice. Furthermore, due especially to the dual curing option, they enable short cycle times and thus efficient production processes.

Adhesives and sealants for control units and plugs

Control units for motor or on-board electronics must be protected from humidity, media and corrosion, even under extreme temperatures. The most important task for adhesives and sealants is therefore the long-term protection of the control unit housing, plugs and other microswitches in the car. Another typical application is thermal management for power electronics. In air conditioning systems, for example, thermally conductive adhesives ensure that the heat generated under load is quickly dissipated to a heat sink.

Many DELO adhesives and sealants are developed specifically for these applications and for some of their special requirements, such as bonding to certain surface coatings. They provide the necessary reliability while enabling efficient production processes thanks to full curing or fixation within seconds and the enabling of in-line tightness testing.
