Product Overview
Our Electronic Potting, also called potting glue or electronic encapsulation glue, is specially engineered for automotive radar sensors—the core component of vehicle ADAS (Advanced Driver Assistance Systems). As a professional supplier of Thermally Conductive Potting Compound and Silicone Potting Compound, we optimize this product for automotive working conditions: it bonds perfectly to PC, PMMA, PCB and automotive metals (aluminum, copper, stainless steel), with excellent waterproof, moisture-proof, insulation, heat dissipation and shock absorption performance. It effectively protects radar sensor electronics from vibration, high temperature, dust and chemical erosion, ensuring accurate signal transmission and long-term stable operation of automotive radar systems. Technical Specifications
Our Electronic Potting has stable performance with fully customizable parameters; key specifications are as follows: it is a dual-component liquid silicone (A and B), available in addition-curing and condensation-curing types. Before curing, it is liquid, with adjustable viscosity according to customer needs. The weight ratio of A and B components is customizable, with an operating time adjustable as required. It supports room-temperature or heated curing, with basic curing for next-process operation and full curing within 24 hours (environment temperature and humidity affect curing speed). It operates continuously from -60℃ to 220℃, with high dielectric strength, volume resistivity, and excellent adhesion to various automotive materials. Shelf life is 12 months when sealed and stored, non-hazardous for general chemical transportation.
Product Features & Advantages
- Automotive-Grade Shock Absorption: Effectively absorbs vehicle vibration and impact during driving, protecting fragile radar sensor chips and welding wires, avoiding signal distortion caused by mechanical damage.
- Dual Curing Options: Available in addition-curing (fast curing for mass production) and condensation-curing (cost-effective) types, flexible to adapt to different automotive radar sensor production workflows.
- High-Temperature Resistance: Stable performance from -60℃ to 220℃, adapting to extreme temperature changes in automotive engine compartments and outdoor driving environments, avoiding performance degradation.
- High-Precision Insulation: Excellent insulation performance (high dielectric strength and volume resistivity) prevents short circuits, ensuring accurate radar signal transmission and avoiding interference with other vehicle electronic systems.
- Strong Adhesion & Corrosion Resistance: Bonds firmly to automotive materials, with high structural strength; resistant to automotive oils, chemicals and ozone, adapting to harsh automotive working environments.
- Low Volatility & Non-Contaminating: Low volatile content, no contamination to precision radar sensor components, ensuring sensor accuracy and service life.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled fillers evenly, and shake Component B thoroughly to ensure uniform viscosity; slight stratification during storage does not affect performance after stirring.
- Component Mixing: Strictly mix Component A and Component B according to the specified weight ratio, stirring continuously until homogeneous to ensure optimal curing effect and sensor protection performance.
- Vacuum Defoaming: After mixing evenly, place the mixed glue in a vacuum container and defoam at 0.01MPa for 3 minutes to remove air bubbles, ensuring dense, bubble-free encapsulation and avoiding signal interference.
- Curing Process: Pour the defoamed glue into automotive radar sensors, cure at room temperature or heat. Proceed to the next process after basic curing, and ensure full curing (24 hours) for optimal protection and performance.
