Thermally Conductive Potting Compound 2.0W/mK UL94 V-0 Silicone Encapsulant for Solar Inverter Power Module Protection
Product Overview
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.
Key Features for Solar Inverter Applications
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
