Thermally Conductive Potting Compound 2.0W/mK UL94 V-0 Anti-Aging Silicone for Automotive LED Lighting Module Encapsulation
Anti-Aging Thermally Conductive Potting Compound HN-8820 AB for Automotive LED Lighting
HN-8820 AB is a two-component 1:1 addition-cure thermally conductive silicone potting compound specially formulated for automotive LED lighting modules and outdoor electronic assemblies. It delivers 2.0 W/m·K thermal conductivity, UL94 V-0 flame retardancy, long-term anti-aging and UV resistance, and complete waterproof protection for reliable heat dissipation and sealing in harsh automotive environments.
Key Features
- Thermal Conductivity 2.0 W/m·K — efficiently transfers heat from LED drivers and power modules to heat sinks, extending service life.
- UL94 V-0 Flame Retardant — meets strict automotive and electronics fire-safety requirements.
- Anti-Aging & UV Resistant — anti-yellowing formula with long-term UV stability, ideal for outdoor automotive lighting.
- Fully Waterproof & Moisture Resistant — protects LED modules, PCBs and connectors from water, dust and corrosion.
- 1:1 Mix Ratio, Easy Processing — low-stress soft elastomer (45-50 Shore A) with 1-2 h pot life at 25℃ for convenient potting.
- Wide Temperature Range — stable performance from -40℃ to 150℃.
Applications
- Automotive LED headlamps, daytime running lights, tail lamps and fog lights
- LED lighting modules and LED driver power supplies
- Outdoor lighting fixtures and signage
- EV onboard electronics and automotive sensor modules
- Industrial control modules requiring heat dissipation and environmental sealing
