Product Overview
Our Electronic Potting for Supercapacitor Cells is a professional Silicone Encapsulant developed specifically for the encapsulation, sealing and protection of supercapacitor cells. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high insulation, low stress and chemical resistance requirements of supercapacitor cells, focusing on insulation, heat resistance, adhesion to electrode/metal and low shrinkage. Compared with ordinary potting compounds, it has better thermal stability, stronger adhesion to supercapacitor electrodes and PCB, and can absorb internal stress caused by high-temperature cycles and charge-discharge processes, effectively protecting supercapacitor cells and pins, reducing failure rates and extending service life for procurement partners.

How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting the curing effect and adhesion to supercapacitor cells and electrode materials.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which will affect the insulation and sealing performance, and prevent damage to delicate supercapacitor cells.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then it can be used for pouring.
- Curing: Pour the degassed potting compound into the supercapacitor cell packaging mold, place it at room temperature for curing or heat to accelerate curing; after basic curing, proceed to the next process, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed.
