Adhesive glue solution for automotive radar ceramics and ceramics: SIPC 1816, ideal for high temperature and humidity resistance

2025-07-11

With the rapid development of smart cars and autonomous driving technologies, automotive radar systems, as key perception devices, have put forward extremely high requirements on the structural stability and reliability of core components. Especially the bonding between ceramic components inside the radar sensor not only needs to withstand high temperature and high humidity environments, but also needs to have excellent insulation performance and durability. Against this background, ELAPLUS’s recommended two-component silicone SIPC 1816 A/B becomes the ideal solution for ceramic bonding and potting. High temperature environment: The working temperature can reach above 120℃, and ordinary glue is prone to aging, hardening, and loss of stickiness;High humidity environment: long-term exposure to humid or condensing environment, and failure caused by water absorption should be prevented;Thermal expansion coefficient matching: Ceramics have small thermal expansion, and the colloid must have low shrinkage and low internal stress;Long-term reliability: It is necessary to ensure a lifespan of more than 10 years to avoid cracking, leakage, debonding and other problems.To solve the above problems, SIPC 1816 came into being. Automotive electronic modules: such as radar antennas, millimeter-wave radar controllers, ADAS main control modules, etc.;Power control module: high-voltage DC-DC converter, inverter, vehicle charger, etc.;Solar module junction box: a packaging environment that requires a UV resistant and high temperature aging;LED lighting system: such as LED spotlights, wall washing lights, LED fluorescent lights, light strips and other waterproof potting protection.Why choose ELAPLUS?As a material technology company focusing on the research and development and manufacturing of electronic adhesives, ELAPLUS is committed to providing customized adhesive solutions for automotive electronics, new energy, optoelectronics, industrial equipment and other industries.
