Product Overview
Our Electronic Potting Compound is specially developed for Photomultiplier Tubes, dedicated to encapsulating, sealing, insulating and protecting PMT cathode, anode, dynode chains and signal transmission components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for ultra-high-sensitivity PMT working scenarios, enhancing low signal interference, high insulation and purity to adapt to the precision requirements of PMTs. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, low shrinkage, and absorbs thermal stress, ensuring stable light-to-electric signal conversion of PMTs.
Key Features & Advantages
- Ultra-High Insulation & Low Interference: High volume resistivity, excellent dielectric strength, isolating internal and external static and electromagnetic interference, avoiding distortion of PMT weak electrical signals, ensuring high-sensitivity light detection and signal conversion accuracy.
- Superior Temperature Adaptability: Stable performance from -60℃ to 220℃, withstanding extreme temperature fluctuations in laboratory and industrial environments; effectively absorbing thermal stress from component operation, protecting PMT dynode chains and welding gold wires from damage.
- High Purity & Low Volatility: Minimal volatile content, no harmful residues or outgassing, ensuring the cleanliness of PMT internal components, avoiding contamination of cathodes/anodes and affecting detection performance.
- Strong Adhesion & Easy Operation: Excellent adhesion to PC, PMMA, PCB, aluminum, copper and stainless steel, ensuring tight sealing of PMT components; adjustable weight mixing ratio, optional vacuum degassing (0.01MPa for 3 minutes), curable at room or heated temperatures, improving encapsulation efficiency.
- Customizable & Reliable: As a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and interference resistance to match different PMT models; strict quality control ensures consistent performance, reducing PMT failure rate.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects insulation and signal interference performance.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly to ensure full integration without air bubbles that cause signal distortion and component damage.
- Degassing (Optional): After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, then pour it into PMT components for encapsulation.
- Curing: Place the encapsulated PMTs at room temperature or heat to accelerate curing; enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed.
