HONG YE SILICONE Electronic Potting Compound for Ion Propulsion Systems is a space-grade two-component Addition Curing Silicone, also known as Silicone Encapsulant and Electronic Encapsulation Adhesive, tailored for ion propulsion equipment. Crafted from high-purity Silicone raw materials, it features adjustable weight mixing ratio, low viscosity, excellent high-temperature resistance (-60℃ to 220℃), radiation resistance and insulation. It cures at room or heated temperatures, with strong adhesion to PC, PMMA, PCB and metals, protecting core ion propulsion components, ensuring stable operation, complying with EU RoHS, and supporting full parameter customization to meet global aerospace equipment procurement demands (around 198 characters).
Product Overview
Our Electronic Potting Compound is specially developed for ion propulsion systems, dedicated to encapsulating, sealing, waterproofing and insulating its core electronic components, ion thruster modules, power control boards and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for aerospace ion propulsion scenarios, enhancing high-temperature resistance and radiation resistance to adapt to the extreme environment of space and ion propulsion operation. Compared with epoxy potting resin, it has better flexibility, minimal volatile content and excellent thermal stability, supports fast curing, and ensures long-term reliable protection for propulsion components, reducing failure rates and maintenance costs for aerospace manufacturers.

- Low Volatility & Customizability: Minimal volatile content, no harmful substances released, avoiding contamination of ion propulsion systems; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and operation time to match different ion propulsion 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 high-temperature 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 insulation performance.
- 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 propulsion 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.
