Solar Inverter & Power Supply Silicone Potting Compound Manufacturer | 3.0 W/m·K Addition-Cure Silicone (HN-8830)

Product Overview:

Shenzhen Hanast New Materials Co., Ltd. is a China-based chemical manufacturer producing HN-8830A/B, a high-performance 3.0 W/m·K high thermal conductivity silicone potting compound designed for outdoor solar inverters, industrial switching power supplies, driver power units, and renewable energy storage systems. Featuring a 1:1 mix ratio by weight and a mixed density of 2.95 g/cm³, HN-8830 flows easily (11,000 mPa·s viscosity) to encapsulate dense transformer coils and high-power PCB assemblies.

HN-8830 provides long-term weatherability, high dielectric insulation (volume resistivity ≥ 1.0 × 10¹⁴ Ω·cm), and UL 94 V-0 flame retardancy across continuous service temperatures from -40°C to +200°C. It offers flexible curing schedules: full room-temperature curing in 4–8 hours at 25°C or accelerated heat curing in 30 minutes at 80°C. Available in 50 kg sets (25 kg Component A + 25 kg Component B plastic barrels), we offer factory-direct export with full SDS/MSDS (non-dangerous goods ocean freight) and Form E / RCEP origin certification.

• Photovoltaic (PV) Solar Inverters: Deep-section potting protecting power conversion circuits from extreme outdoor temperatures and moisture.

• Switching Power Supplies & LED Drivers: Thermal management for high-density industrial driver power supplies.

• Commercial Energy Storage Systems (ESS): Insulation and thermal conduction for battery management and power control modules.

A: HN-8830 uses a platinum catalyst system. To prevent cure inhibition, ensure potting equipment and electronic substrates are free from organotin compounds, sulfur/polysulfides, amines, polyurethane residues, phosphorus, acidic materials, and solder flux residues.

A: HN-8830 is packaged in a 50 kg/set kit (25 kg A + 25 kg B plastic barrels). Stored in original sealed containers at 5–25°C, it has a shelf life of 6 months from the manufacturing date. It is shipped as non-dangerous general chemicals.
