Shenzhen Potting Compound Factory 1:1 Low Viscosity RTV Silicone Potting Compound for IGBT Power Module

HANAST HN-8806 A/B 1:1 Low Viscosity RTV Silicone Potting Compound for IGBT Power Module

HN-8806 A/B is a two-component 1:1 RTV silicone potting compound developed for IGBT power module encapsulation and EV charging pile electronics protection. Produced by our Shenzhen potting compound factory in Guangdong, China, it flows readily for complete under-fill around IGBT modules and dense power assemblies, then cures at room temperature or by heating into a high-performance grey elastomer that combines thermal conductivity, UL94 V-0 flame retardancy and reliable high-voltage insulation.

Key Features

• Low viscosity for complete penetration and under-fill around IGBT modules and dense SMD assemblies
• Thermal conductivity of 0.76 W/m·K or more for heat dissipation in power modules
• High dielectric strength of 25-30 kV/mm for high-voltage power electronics
• UL94 V-0 flame retardancy and RoHS compliance for public charging infrastructure safety
• Wide operating temperature range from -50°C to 250°C
• 1:1 mix ratio by weight with room temperature or heat-accelerated curing
• Deep-section curing with extremely low cure shrinkage and no stress on IGBT wire bonds
• No heat or by-products released during cure; non-corrosive to sealed components
• Short 18-24 minute pot life at 25°C for efficient production
• RoHS and REACH compliant, supplied as non-dangerous goods with SDS available

Typical Applications

• IGBT power modules in inverters, motor drives and power converters
• EV charging pile and fast-charging station power modules
• Battery pack BMS boards, fast-charging adapters and high-voltage transformers
• 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 low viscosity RTV silicone potting compound. It is designed for IGBT power modules, EV charging pile power modules, battery pack BMS boards and high-voltage transformers requiring insulation, heat dissipation and moisture protection.

Q2: Is the viscosity low enough for IGBT under-fill and dense PCBs?
A2: Yes. Its low viscosity allows complete penetration and under-fill around IGBT modules, transformers and dense SMD assemblies without trapped air pockets.

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: What is the dielectric strength, thermal conductivity and temperature range?
A4: Dielectric strength is 25-30 kV/mm, thermal conductivity is 0.76 W/m·K or more, and the operating temperature range is -50°C to 250°C, with UL94 V-0 flame retardancy.

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