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.
- Technical challenges of automotive radar ceramic sticky ceramics
Ceramic materials are widely used in high-performance electronic components such as automotive radar modules and power electronic modules due to their excellent electrical insulation and thermal stability. However, the bonding between ceramics and ceramics faces many technical challenges:
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.
- Recommended products: SIPC 1816 A/B flame retardant silicone potting glue
SIPC 1816 A/B Applicable to potting protection for various components. It can be cured deeply, and the two-components have good fluidity after mixing. The operating time can adjust the ratio of the curing agent to the temperature. No other primer is required before use, and it has a good bonding effect on most materials and is suitable for fixing accessories, waterproof, dustproof and leakage protection.
■Bi-component, condensation and dehydration type
■Low viscosity, easy to process, strong operation
■Low hardening shrinkage rate, no corrosion and no stress
■Excellent high-temperature electrical insulation and stability
■Excellent adhesion, good waterproof and moisture-proof
■Fire retardant type complies with UL 94 V-0 - Typical application scenarios
SIPC 1816 is not only suitable for bonding and potting between ceramics, but also widely used in other occasions where reliability requirements are extremely high:
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.
