Product Overview
Our Electronic Potting, also called potting glue or encapsulation silicone, is a professional Silicone Encapsulant specially engineered for high-voltage power modules—the core component ensuring safe power transmission and conversion in high-voltage scenarios. As a professional supplier of Thermally Conductive Potting Compound and industrial silicone solutions, we optimize this product for high-voltage use: it is a dual-component liquid silicone that cures into a solid after adding curing agent, with excellent waterproof, moisture-proof, corrosion-resistant and high-voltage insulation performance. It bonds perfectly to PC, PMMA, PCB and high-voltage-grade metals (aluminum, copper, stainless steel), effectively isolating high voltage, dissipating heat and protecting module components from damage. Technical Specifications
Our Electronic Potting has stable high-voltage performance with fully customizable parameters: dual-component Addition Curing Silicone, A/B weight ratio adjustable, liquid before curing, requiring thorough stirring of Component A (to mix settled fillers) and shaking of Component B before mixing. Optional vacuum defoaming at 0.01MPa for 3 minutes before pouring, supports room-temperature or heated curing, basic curing for next process, full curing within 24 hours (temperature and humidity affect curing). It operates continuously from -60℃ to 220℃, low volatility, high strength, excellent adhesion to metals and electronic materials, with superior high-voltage insulation and thermal conductivity. Shelf life is 12 months (sealed storage), non-hazardous for transportation.

- High Strength & Superior Adhesion: Low volatility, high structural strength after curing, bonds firmly to high-voltage module materials (metals, PC, PCB), no detachment even under high voltage and vibration.
- Comprehensive Protection: Excellent waterproof, moisture-proof, corrosion-resistant and dust-proof performance, isolating harsh industrial environments, protecting high-voltage components from damage.
- Dual Curing & Customizable: Available in addition-curing and condensation-curing types, adjustable hardness, viscosity and operating time, adapting to different high-voltage power module sizes and production processes.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled fillers evenly, shake Component B thoroughly; slight stratification during storage does not affect performance after stirring.
- Component Mixing: Strictly mix A and B according to the specified weight ratio, stir continuously until homogeneous to ensure optimal high-voltage insulation and curing performance.
- Vacuum Defoaming: If needed, place the mixed glue in a vacuum container and defoam at 0.01MPa for 3 minutes to remove bubbles, ensuring dense, bubble-free encapsulation without insulation gaps.
- Curing Process: Pour the defoamed glue into high-voltage power modules, cure at room temperature or heat. Proceed to the next process after basic curing; full curing (24 hours) ensures optimal high-voltage protection.
