Product Overview
Our Electronic Potting Silicone is specially developed for magnetic resonance spectroscopy equipment, dedicated to encapsulating, sealing, filling and protecting its core electronic components, signal processing modules, sensor units and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for MRS scenarios, minimizing dielectric loss and enhancing signal compatibility to avoid interfering with magnetic resonance signals. Compared with epoxy potting resin, it has better flexibility and thermal stability, supports room-temperature or heated curing, and ensures long-term reliable protection for MRS components, reducing maintenance costs and extending equipment service life for medical and scientific research institutions.
Key Features & Advantages
- Ultra-Low Signal Interference: Optimized formula with ultra-low dielectric loss and high volume resistivity (≥1.0×10¹⁶ Ω·cm), effectively avoiding interference with MRS signals, ensuring accurate signal acquisition and analysis, which is crucial for precision spectroscopy testing.
- Excellent Thermal Stability: Operates stably from -60℃ to 220℃, withstanding temperature fluctuations during MRS operation, absorbing internal thermal stress to protect chips, welding gold wires and precision sensors from damage.
- High Purity & Low Volatility: Made of high-purity silicone raw materials, with ultra-low volatile content, no harmful substances released, avoiding contamination of MRS detection environment and ensuring test accuracy.
- Strong Adhesion & Corrosion Resistance: Excellent bonding to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), ensuring tight sealing; resistant to chemical erosion and ozone, maintaining stable performance in long-term use.
- Flexible Curing & Customizability: Addition-curing formula, fully cured in 24 hours at room temperature (accelerated by heating); as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different MRS equipment models.
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 signal compatibility and adhesion.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly for 2-3 minutes to avoid air bubbles that affect sealing and signal stability.
- Degassing: Place the mixed adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of MRS components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature or heat to accelerate, enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed.
