Product Overview
Our Electronic Potting, also called potting glue or encapsulation silicone, is a high-performance Silicone Encapsulant specially engineered for solar charge controllers—the key component converting solar energy to electrical energy and stabilizing charging. As a professional supplier of Thermally Conductive Potting Compound and industrial silicone solutions, we optimize this product for solar charging scenarios: it bonds perfectly to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), with excellent waterproof, moisture-proof, corrosion-resistant, insulation and shock absorption performance. It effectively protects controller electronics from intense sunlight, UV radiation, temperature cycles and humidity, ensuring efficient, stable solar energy conversion and charging. Technical Specifications
Our Electronic Potting has stable performance with fully customizable parameters; key specifications: it is dual-component addition-curing liquid silicone (A and B), A component needs full stirring to mix settled fillers, B component needs thorough shaking. A/B weight ratio is adjustable; optional vacuum defoaming (0.01MPa for 3 minutes) before pouring. It 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℃, with high dielectric strength, low volatility, high strength, excellent adhesion and efficient thermal conductivity. Shelf life is 12 months sealed, non-hazardous for transportation. Product Features & Advantages
- Strong UV & Outdoor Weather Resistance: Resists intense UV radiation and outdoor harsh weather (rain, snow, ozone), avoiding material aging, ensuring long-term operation of solar charge controllers in outdoor environments.
- Efficient Thermal Conductivity: Rapidly dissipates heat generated by controller components during charging, preventing overheating, protecting chips and ensuring stable charging efficiency.
- Superior Waterproof & Insulation: Excellent sealing and insulation performance, isolating moisture, rainwater and dust, preventing short circuits and ensuring safe charging operation.
- Wide Temperature Adaptability: Stable from -60℃ to 220℃, adapting to extreme temperature changes in different regions, avoiding performance loss in cold or high-temperature environments.
- Strong Adhesion & Low Volatility: Bonds firmly to solar equipment materials, high structural strength; low volatile content, no contamination to precision components, ensuring long-term stability.
- Dual Curing & Customizable: Available in addition-curing and condensation-curing types, adjustable curing speed and viscosity, adapting to mass production workflows.
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 specified weight ratio, stir continuously until homogeneous for optimal curing and thermal conductivity.
- Vacuum Defoaming: Place mixed glue in a vacuum container, defoam at 0.01MPa for 3 minutes to remove bubbles, ensuring dense, bubble-free encapsulation.
- Curing Process: Pour defoamed glue into solar charge controller components, cure at room temperature or heat. Proceed to next process after basic curing; full curing (24 hours) ensures optimal protection.
