Product Overview
Our Electronic Potting Compound is specially developed for Electrochemical Gas Sensors, dedicated to encapsulating, sealing, waterproofing and insulating its core electronic components, gas sensing modules, signal processing boards and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for electrochemical gas detection scenarios, enhancing chemical corrosion resistance and low interference to adapt to the high-precision, anti-pollution requirements of gas sensing. Compared with epoxy potting resin, it has better flexibility, minimal volatile content and excellent environmental adaptability, supports fast curing, and ensures long-term reliable protection for sensor components, reducing failure rates and maintenance costs for gas detection equipment manufacturers.
Key Features & Advantages
- Excellent Chemical Corrosion Resistance: Optimized formula, resistant to corrosive gases (such as CO, NO₂, SO₂) and chemical vapors, avoiding material degradation and sensor failure, ensuring stable operation in harsh gas detection environments.
- Low Interference & High Detection Accuracy: Minimal volatile content and low dielectric loss, no interference with electrochemical reaction signals of gas sensors, guaranteeing accurate gas concentration detection and stable data output.
- High Insulation & Strong Adhesion: High volume resistivity (≥1.0×10¹⁶ Ω·cm), excellent dielectric strength (≥25 kV/mm), isolating external electromagnetic interference; strong adhesion to PC, PMMA, PCB and metals (aluminum, copper, stainless steel), ensuring tight sealing and structural stability.
- Low Viscosity & Flexible Curing: Low viscosity, good fluidity, able to penetrate tiny gaps of sensor components; addition-curing formula, cures at room or heated temperatures, fully cured in 24 hours, easy to operate and improve production efficiency.
- Low Volatility & Customizability: Minimal volatile content, no harmful substances released, avoiding contamination of gas sensing elements; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different electrochemical gas sensor 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 corrosion resistance and adhesion.
- 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 affect sealing and signal stability.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of gas sensor 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.
