Thermally Conductive Potting Compound 2.0W/m·K UL94 V-0 Silicone for Network Transformer Power Module Potting

HN-8820 is a two-component addition-cure silicone potting compound delivering 2.0 W/m·K thermal conductivity with UL 94 V-0 flame retardant certification. Engineered for network transformer encapsulation, automotive power modules, and industrial electronics, this high-performance silicone provides superior electrical insulation (volume resistivity >5.0*10¹⁴ Ω·cm) with a convenient 1:1 mix ratio for easy processing. Operates reliably from -40°C to 150°C with excellent waterproof and anti-aging properties.

• 2.0 W/m·K Thermal Conductivity: Excellent heat dissipation for power-dense electronics — effectively prevents thermal buildup in transformers, converters, and power modules
• UL 94 V-0 Flame Retardant: Self-extinguishing within 10 seconds on 3mm samples — critical fire safety compliance for telecom, automotive, and industrial electronics
• High Electrical Insulation: Volume resistivity >5.0*10¹⁴ Ω·cm provides reliable isolation for high-voltage power electronics and transformer windings
• 1:1 Mix Ratio: Simple, error-resistant processing for manual potting or automated dispensing production lines
• Waterproof & Anti-Aging: Complete moisture barrier with excellent resistance to yellowing and thermal degradation over extended service life
• Wide Temperature Range (-40°C to 150°C): Stable dielectric and mechanical properties across extreme operating conditions
• Deep Section Cure: Addition-cure chemistry cures uniformly at any depth without releasing heat or by-products — ideal for large transformer and power module housings

• Network Transformers: High-frequency transformer and inductor potting for telecom equipment, Ethernet magnetics, and POE power supplies. Provides thermal management, electrical insulation, and moisture protection in compact transformer housings.
• Automotive Power Modules: DC-DC converter, ECU, and HID lighting ballast encapsulation. Delivers vibration-resistant potting with reliable thermal management for under-hood automotive electronics.
• Industrial Power Supplies: SMPS, AC-DC converters, and industrial power distribution module protection with combined flame retardancy and heat dissipation for factory automation applications.
• LED Drivers & Luminaires: High-power LED driver encapsulation for indoor and outdoor lighting. Extends service life through efficient heat dissipation and moisture-proof sealing.
• Sensor & Instrumentation Modules: Environmental protection for industrial sensors, process control instruments, and IoT edge devices operating in harsh or outdoor conditions.
• General Electronics Encapsulation: Versatile potting solution for PCB assemblies, connectors, junction boxes, and electronic sub-systems requiring UL 94 V-0 fire safety compliance and thermal management.
