HONG YE SILICONE Electronic Potting Compound for Magnetoencephalography (MEG) is a high-precision two-component Addition Curing Silicone, also known as Silicone Encapsulant and Electronic Encapsulation Adhesive, tailored for MEG equipment. Crafted from high-purity Silicone raw materials, it features adjustable weight mixing ratio, low viscosity, ultra-low electromagnetic interference, and temperature adaptability (-60℃ to 220℃). It cures at room or heated temperatures, adheres well to PC, PMMA, PCB and metals, protects MEG core components, ensures signal accuracy, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting Compound is specially developed for Magnetoencephalography (MEG) systems, dedicated to encapsulating, sealing, insulating and protecting MEG core components, magnetic sensors, signal acquisition modules, PCB substrates and electrode connections. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for MEG scenarios, enhancing ultra-low electromagnetic interference and high stability to adapt to the ultra-high precision, low-noise requirements of brain magnetic signal detection. Compared with epoxy potting resin, it has minimal volatile content, excellent temperature adaptability, no exotherm during curing, and absorbs internal stress, ensuring long-term reliable operation of MEG components and reducing signal interference.
Key Features & Advantages
- Ultra-Low Electromagnetic Interference: Optimized formula with minimal magnetic permeability, avoiding interference with brain magnetic signal detection and acquisition, ensuring accurate MEG data collection and analysis, which is the core advantage for MEG equipment procurement.

- Low Viscosity & Flexible Curing: Low viscosity, good fluidity, penetrating tiny gaps of MEG sensors and modules; addition-curing formula, cures at room or heated temperatures, fully cured in 24 hours, easy to operate and improve production efficiency.
- Strong Adhesion & Customizability: Excellent adhesion to PC, PMMA, PCB, aluminum, copper and other metals, ensuring tight sealing of MEG components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and curing speed to match different MEG system 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 insulation and electromagnetic compatibility.
- 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 interference.
- 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 MEG 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.
