HN-8820 is a high-performance two-part addition-cure silicone potting compound manufactured by Shenzhen Hanast New Material Co., Ltd. Engineered specifically for EV battery module heat dissipation, energy storage systems, and power electronics, this RTV-2 silicone encapsulant delivers 2.0W/mK thermal conductivity with UL 94 V-0 flame retardant certification.

• Superior Thermal Management: 2.0W/mK thermal conductivity effectively prevents thermal runaway in high-power density modules
• UL 94 V-0 Flame Retardant: Certified for maximum fire safety in high-voltage electronics
• 1:1 Mix Ratio: Convenient processing with simple dispensing systems
• High Electrical Insulation: Volume resistivity >5.0E14 Ohm.cm, dielectric strength >25 kV/mm
• Broad Operating Range: Reliable protection from -40°C to 150°C
• Deep Section Cure: Addition-cure system cures uniformly at any depth without releasing heat
• Waterproof & Anti-aging: Excellent moisture resistance and long-term durability
