Fast Curing RTV Silicone Potting Compound 1:1 High Voltage for EV Battery Inverter Module

Fast Curing RTV Silicone Potting Compound 1:1 High Voltage for EV Battery Inverter Module

This two-component RTV addition-cure silicone potting compound uses a 1:1 mix ratio and cures fast at room temperature, or in about 0.2 hour at 80°C, into a high-performance grey elastomer. Engineered for high-voltage electrical insulation, it combines a 18-25 kV/mm dielectric strength and 1.0x10¹⁶ ohm.cm volume resistivity with 0.76 W/m·K thermal conductivity and a wide -50°C to +250°C range. It is ideal for potting and sealing EV battery inverters, power modules, high-voltage transformers, fast-charging adapters and LED drivers.

Key Features

• Fast Curing RTV — room-temperature vulcanizing, initial cure in 4-12 hours and 0.2 hour at 80°C for high throughput
• High Voltage Insulation — dielectric strength 18-25 kV/mm and volume resistivity 1.0x10¹⁶ ohm.cm for high-voltage power electronics
• EV Battery / BMS Potting — durable encapsulation for battery packs, inverters and battery management modules
• Thermally Conductive 0.76 W/m·K — effectively transfers heat from power components
• Low Viscosity & Flowability — penetrates dense layouts and deep cavities for void-free potting
• Wide Temperature Range -50°C to +250°C — excellent heat resistance and cold-environment stability
• Low Shrinkage, No By-products — addition cure releases no heat or corrosive by-products, safe for sensitive circuits
• 1:1 Mix Ratio — simple, accurate dosing for consistent production

Applications

• EV battery inverter and BMS module potting
• High-voltage transformer and power module encapsulation
• Fast-charging adapter and power supply sealing
• LED driver and circuit board protection
