Guangdong Potting Compound Factory 1:1 Waterproof Silicone Electronic Potting Gel for Solar Inverter BESS

HANAST HN-8806 A/B 1:1 Waterproof Silicone Electronic Potting Gel for Solar Inverter and BESS

HN-8806 A/B is a two-component 1:1 RTV silicone electronic potting gel developed for solar inverter PCB protection and BESS (Battery Energy Storage System) power module encapsulation. Produced by our Guangdong potting compound factory in Shenzhen, China, it cures at room temperature or by heating into a flexible grey elastomer that absorbs thermal expansion stress while providing waterproof sealing, thermal conductivity and UL94 V-0 flame retardancy for renewable energy power electronics.

Key Features

• Flexible cured elastomer that absorbs thermal expansion and contraction stress
• Waterproof and moisture proof sealing for outdoor solar and BESS installations
• Deep-section curing with uniform cure through thick power module sections
• Thermal conductivity of 0.76 W/m·K or more for heat dissipation
• High dielectric strength of 25-30 kV/mm for high-voltage solar string inverters
• UL94 V-0 flame retardancy and RoHS compliance for energy storage safety
• Low shrinkage, non-corrosive and no exotherm during cure
• Wide operating temperature range from -50°C to 250°C
• 1:1 mix ratio by weight with room temperature or heat-accelerated curing
• RoHS and REACH compliant, supplied as non-dangerous goods with SDS available

Typical Applications

• Solar inverter PCB: MPPT controllers, DC-AC inverter boards and power semiconductors
• BESS energy storage: battery management modules, DC-DC converters and power distribution units
• Industrial power electronics: IGBT modules, charging pile controllers and UPS systems
• Power modules and circuit boards with heat dissipation requirements
• Sensors, controllers and general electronic appliances requiring insulation and moisture resistance
• Applications requiring deep-section curing and low shrinkage

FAQ

Q1: What is HN-8806 A/B and which applications does it suit?
A1: HN-8806 A/B is a 1:1 flexible silicone electronic potting gel. It is designed for solar inverter PCBs, BESS energy storage power modules, IGBT modules and charging pile controllers requiring insulation, heat dissipation and waterproof protection.

Q2: Is it waterproof and suitable for outdoor solar installations?
A2: Yes. It provides waterproof and moisture-proof sealing with thermal conductivity of 0.76 W/m·K or more and a -50°C to 250°C operating range, suitable for outdoor solar inverters and energy storage cabinets.

Q3: What is the mix ratio and curing schedule?
A3: Mix Component A and Component B at a 1:1 ratio by weight, with an 18-24 minute pot life at 25°C. It cures at room temperature in 2-3 hours (preliminary) or in 12 minutes at 80°C for fast cure.

Q4: Is the cured gel flexible and does it protect against stress?
A4: Yes. It cures into a flexible grey elastomer that absorbs thermal expansion and contraction stress, helping prevent solder joint fatigue in solar inverter and BESS power PCBs.

Q5: Where is it manufactured and what certifications, MOQ and packaging are available?
A5: It is manufactured in our Guangdong potting compound factory in Shenzhen, China. HN-8806 A/B is RoHS and REACH compliant, UL94 V-0 flame retardant, and classified as non-dangerous goods, supplied in 50kg/set (25kg A + 25kg B) kits with OEM/ODM bulk supply supported.
