Behind the functionality of advanced driver assistance systems (ADAS), battery electric vehicles (BEVs) and new autonomous vehicle technologies is a complex electronic network that powers all of the microcomputers, microprocessors, sensors, cameras, lidars and radars that make these systems seemingly work magic with remarkable reliability. The use of in-vehicle electronics will continue to grow at a rapid rate over the next 10 years to reach approximately 50 percent of a vehicle’s value before 2030. 

More miles of wire will be added to already complex wiring harnesses to carry the increased electric load. With more junctions branching off at various locations to power different vehicle systems, enhancing reliability and optimizing performance of electronic technologies is imperative. 

Adhesive and sealant solutions ensure that in-vehicle electronic systems and overall vehicle electronics perform at optimal levels to deliver an intelligent, connected experience for driver safety and satisfaction. Henkel material solutions provide a gateway for complex connectivity and expanded functionality in the ever-evolving demand on the highly sensitive components that make up these advanced vehicle systems, to ensure its accuracy and reliability. They protect against overheating, mechanical shock, electromagnetic interference, environmental influences and other factors that can degrade functionality and reduce longevity. As the auto industry continues to transition to the mobility space, solutions like thermal interface materials, printed heaters, and advanced coatings will be essential to keep BEV battery packs from overheating, maintaining camera lens clarity, and other similar challenges uniquely presented by this new era in the automotive market. 

Henkel’s wide array of sealants, including liquid gasketing, foam gasketing, vacuum impregnation, potting and low-pressure molding, are key to protecting vehicle electronics from moisture, dust and chemical corrosion while facilitating operation at high temperatures. In addition, Henkel’s adhesive coatings are rapid UV-cured, which eliminates the heat processing that could potentially diminish the effectiveness of vehicle electronics.

Adhesive coatings for the camera lenses enable more robust function by handling the wide range of temperatures to which they are exposed to maintain a high level of clarity for detecting images that are relayed to the sensors. First, the lens is calibrated, then the adhesive is applied. The underlying hardware that powers ADAS is what enables active safety in the vehicle. These systems also enable varying levels of vehicle autonomy.                                      

Working at the Tier 1 and Tier 2 levels to understand its customers’ needs, Henkel develops adhesives for applications at all levels of the supply chain. Evaluating a solution from the customer perspective (Tire 1) and then taking the product through its material testing, Henkel has the expertise go-to partnership with OEMs on future product development. 

Henkel’s solutions for vehicle electronics can be found in a wide array of components in the vehicle powertrain with conventional internal combustion engines as well as hybrid electric vehicles and battery electric vehicles. Applications include electronic control units, sensors, cameras, connectors, displays, wire harnesses and more. Adhesives are essential enablers for mobility, and Henkel is leading the way in powering tomorrow’s vehicles. 

Potential for lightweighting with hybrid designs using high-performance structural foam in body and closure panels.
