Thermally Conductive Potting Compound HN-8820-PV 2.0W/mK Silicone Encapsulant for Solar Inverter Outdoor Electronics
Product Overview
HN-8820-PV is a RoHS and REACH certified two-component addition-cure silicone potting compound manufactured for solar photovoltaic inverter encapsulation, renewable energy power electronics, and outdoor electrical equipment protection. With 2.0W/mK thermal conductivity and UL 94 V-0 flame retardancy, this waterproof electronic potting compound delivers reliable long-term protection in harsh outdoor environments.
Key Features for Renewable Energy Applications
- Outdoor Weather Resistance: Superior UV, humidity, and thermal shock resistance for solar inverter field deployment
- Waterproof & Moisture-Proof: IP-level environmental sealing against rain, condensation, and dust ingress
- Anti-Vibration Performance: Flexible silicone maintains integrity under wind-induced vibration and mechanical stress
- Anti-Aging Formulation: Long service life without yellowing or embrittlement after years of outdoor exposure
- RoHS & REACH Certified: Fully compliant for EU and international renewable energy supply chains
- 1:1 Mix Ratio: Simple processing compatible with automated dispensing systems
- Thermal Runaway Prevention: 2.0W/mK conductivity efficiently dissipates heat from IGBT and MOSFET power stages
