millimeter wave radar
As the intelligent driving functions of new energy vehicles continue to be upgraded, millimeter-wave radar, as an important sensing component of ADAS, is exposed to complex environments such as high and low temperatures, humidity and heat, vibration and dust for a long time, which puts forward higher requirements for structural sealing and environmental reliability. Adhesives are widely used in key parts such as radar casings, PCBs and connectors to achieve sealing protection, structural fixation and long-term reliability guarantee, ensuring the stable operation of radar systems.

As the core sensing component of autonomous driving, vehicle-mounted millimeter-wave radar is extremely susceptible to electromagnetic noise interference generated by vehicle-mounted motors, DC-DC power supplies, and vehicle wiring harnesses. At the same time, radar modules have long faced problems such as bumps and vibrations, sudden changes in temperature, and rain and dust erosion. Electromagnetic shielding glue is formed on-site on the surface of the device through a dispensing process. After curing, it relies on conductive fillers to form a dual electromagnetic wave attenuation mechanism of absorption loss + reflection loss, realizing the three core functions of electromagnetic shielding, structural bonding, and waterproof and dustproof sealing in one stop.
