Silicone Potting Compound Two Component 1:1 Mix Ratio UL 94 V-0 Flame Retardant for LED Driver Thermal Management
Product Overview
HN-8806 is a high-performance two-component 1:1 addition cure silicone potting compound purpose-built for LED driver thermal management and outdoor lighting encapsulation. Featuring UL 94 V-0 flame retardancy, 0.76 W/m·K thermal conductivity, and IP67-equivalent waterproof protection, it ensures long-term reliability for LED power supplies, street lighting, stadium floodlights, and industrial lighting systems. Available in factory-direct bulk supply with competitive wholesale pricing and free sample evaluation.
Key Features for LED Driver Potting
- ✅ 1:1 Simple Mix Ratio — Easy metering for both manual and automated LED driver production lines
- ✅ UL 94 V-0 Flame Retardant — Self-extinguishing material critical for enclosed LED driver housings
- ✅ 0.76 W/m·K Thermal Conductivity — Efficient heat dissipation extending LED driver lifespan
- ✅ IP67 Waterproof Protection — Superior moisture and water ingress resistance for outdoor and wet-location lighting
- ✅ 18-25 kV/mm Dielectric Strength — Robust electrical insulation for AC-DC LED power supplies
- ✅ -50°C to 250°C Temperature Range — Stable performance from freezing winter to high-temperature enclosure environments
- ✅ Low Viscosity 4500-5000 mPa·s — Excellent flowability for complete penetration around complex LED PCB assemblies
- ✅ Non-Corrosive & Flexible After Cure — Shore A 50±5 elastomer protects delicate SMD components without stress cracking

Target Applications
Encapsulates AC-DC and DC-DC LED driver circuits for indoor and outdoor lighting fixtures.
IP67 waterproof protection for street lights, floodlights, tunnel lights, and stadium lighting exposed to rain and humidity.
Protects industrial power supplies, inverters, and converters from dust, moisture, and vibration.
How to Use
- Weigh Part A and Part B at 1:1 ratio by weight or volume in a clean mixing container.
- Mix thoroughly for 2-3 minutes until uniform color is achieved. Vacuum degassing recommended for bubble-free potting.
- Pour or dispense the mixed compound into the LED driver housing, ensuring complete coverage of PCB and components.
- Cure at room temperature for 4-12 hours, or heat-accelerate at 80°C for approximately 12 minutes for high-throughput production lines.
- For automated production: use a metering pump with static mixer for continuous dispensing.
