Thermally Conductive Potting Compound 2.0W/mK UL94 V-0 Silicone Encapsulant for Solar Inverter Power Module Protection

HN-8820 is a high-performance two-part addition-cure silicone potting compound engineered for solar inverter power module encapsulation and photovoltaic system protection. This RTV-2 silicone encapsulant delivers 2.0W/mK thermal conductivity with UL 94 V-0 flame retardant certification, providing reliable heat dissipation and environmental sealing for MPPT controllers, DC-AC inverter stages, and power conversion modules in utility-scale and residential solar installations. Manufactured by Shenzhen Hanast New Material Co., Ltd. with a 40,000 sqm production base for reliable bulk supply to PV system integrators.

• 2.0W/mK Thermal Conductivity: Efficiently dissipates heat from high-power IGBT and MOSFET modules in solar inverter power stages, preventing thermal throttling
• UL 94 V-0 Flame Retardant: Maximum fire safety certification for grid-connected photovoltaic equipment
• High Dielectric Strength (>25 kV/mm): Critical for safe isolation in 1000V/1500V DC solar PV systems
• 1:1 Mix Ratio: Simple processing for automated potting of inverter modules on production lines
• Outdoor Durability: Resists UV degradation, moisture ingress, and temperature swings from desert to rooftop deployments
• Deep Section Cure: Uniform curing at any depth without exothermic reaction — ideal for large inverter power modules
• Anti-Aging Performance: Maintains dielectric and thermal properties over 15+ year solar installation lifecycles

• Solar PV Inverters: Complete encapsulation and thermal management for string inverters, central inverters, and microinverters. Protects IGBT/MOSFET power stages, DC-DC boost converters, and MPPT circuitry from environmental stress while ensuring reliable heat dissipation in outdoor deployments.
• Energy Storage PCS: Power conversion system potting for battery energy storage installations. Provides high-voltage insulation and thermal management for bidirectional AC-DC and DC-DC converter modules in megawatt-scale ESS deployments.
• EV DC Fast Charging Stations: Power module encapsulation for 50kW-350kW DC fast chargers. Dissipates heat from high-power rectifier stacks while providing moisture and dust protection for outdoor charging infrastructure.
• IGBT & Power Semiconductor Modules: Industrial-grade encapsulation for power semiconductor devices in renewable energy converters, traction applications, and industrial motor drives requiring combined high-voltage isolation and thermal management.
• 5G Base Station Power Supplies: Thermally conductive potting for outdoor telecom rectifier modules and power distribution units operating in uncontrolled environments.
• Wind Power Converters: Reliable environmental protection and heat dissipation for power converter modules in wind turbine nacelles exposed to extreme temperature variations and vibration.
