Description
Thermally Conductive Potting Compound 2.0W/m·K UL94 V-0 Waterproof Silicone for EV Onboard Charger DC-DC Converter
Waterproof Potting Compound HN-8820 AB for EV Onboard Charger & DC-DC Converter Protection

HN-8820 AB is a waterproof and anti-aging two-component silicone potting compound with 2.0 W/m·K thermal conductivity and UL 94 V-0 flame retardant certification. Purpose-engineered for EV onboard charger (OBC), DC-DC converter, and high-power electronic module encapsulation, this silicone encapsulant provides complete environmental sealing against moisture, vibration, and thermal stress while efficiently dissipating operational heat. Ensures long-term reliable protection for automotive-grade power electronics exposed to harsh under-vehicle and engine-bay environments.

Key Protection Features
  • 2.0 W/m·K Thermal Conductivity: Efficiently dissipates heat from IGBT, MOSFET, and transformer components inside onboard charger and DC-DC converter modules, preventing hot-spot failure
  • UL 94 V-0 Flame Retardant: Meets stringent fire-safety requirements for automotive power electronics and lithium battery adjacent modules
  • Fully Waterproof After Curing: IP-grade protection against moisture, condensation, salt spray, and coolant ingress for under-vehicle electronics
  • 1:1 Mix Ratio by Weight: Simple and accurate dispensing with low mixing error, suitable for automatic metering and potting production lines
  • Vibration & Shock Damping: Flexible silicone matrix absorbs mechanical shock and thermal expansion stress during vehicle operation
  • Wide Temperature Range: Stable performance from -40℃ to 150℃, covering extreme cold-start and high-load operating conditions
  • Excellent Adhesion: Bonds reliably to aluminum housings, PCB, PBT, and metal busbars without primer
Applications
EV Onboard Charger (OBC)

Encapsulation of AC-DC power stages, PFC inductors, and control boards in vehicle onboard chargers, providing thermal management and waterproof protection for 6.6kW to 22kW charging systems.

DC-DC Converters

Potting of high-frequency transformers, inductors, and power semiconductors in automotive DC-DC converters, ensuring reliable heat dissipation and insulation in confined enclosures.

Power Module & BMS Protection

Sealing of power modules, battery management system boards, and junction boxes in electric vehicles and hybrid vehicles against moisture and mechanical stress.

Industrial & Energy Storage Inverters

Protection of inverter power stages, charging pile modules, and energy storage converters operating in outdoor and high-humidity environments.
