Product Overview
Our Electronic Potting for Tantalum Capacitors is a professional Silicone Encapsulant developed specifically for the encapsulation, sealing and protection of tantalum capacitors. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the high reliability and precision requirements of tantalum capacitors, focusing on insulation, heat resistance, adhesion and stability. Compared with ordinary potting compounds, it has better thermal stability, stronger adhesion to metal and PCB, and can absorb internal stress caused by high-temperature cycles, effectively protecting tantalum capacitor chips and welding gold wires, reducing failure rates and extending service life for procurement partners.
Key Features & Advantages
- Superior Insulation & Safety: Excellent dielectric properties, strong insulation performance, effectively isolating tantalum capacitors from external electrical interference, preventing short circuits and leakage, ensuring the stable operation of electronic components, meeting the strict insulation requirements of tantalum capacitors.
- Wide Temperature Adaptability: High temperature resistance (-60℃ to 220℃) and excellent low-temperature performance, can operate stably in extreme temperature environments, absorb internal stress caused by high-temperature cycles, and protect tantalum capacitor chips and welding gold wires from damage.
- Strong Adhesion & Sealing: Good adhesion to tantalum capacitors, PCB, aluminum, copper, stainless steel, PC and PMMA, forming a tight seal, effectively achieving waterproof, moisture-proof, dust-proof and anti-corrosion effects, extending the service life of tantalum capacitors.
- Easy Operation & Fast Curing: Two-component liquid design, simple mixing ratio, easy to stir evenly; supports room temperature or heat curing, full curing in 24 hours, optional vacuum degassing, improving production efficiency for batch production of tantalum capacitors.
- High Stability & Environmental Protection: Low volatility, high strength, no harmful substances, complying with EU RoHS and international environmental standards; no stratification or performance degradation after long-term storage, ensuring consistent product quality.
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 product performance.
- 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.
- 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灌注.
- Curing: Pour the degassed potting compound into the tantalum capacitor 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.
