Product Overview
Our Electronic Potting Compound is specially developed for Atomic Clocks, dedicated to encapsulating, sealing, insulating and protecting atomic clock oscillators, frequency control modules, PCB substrates, precision chips and signal transmission components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for ultra-high-precision timekeeping scenarios, enhancing low signal interference, high stability and environmental adaptability to adapt to the extreme precision, low-noise operation requirements of atomic clocks. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, low shrinkage, and absorbs thermal stress, ensuring long-term reliable operation of atomic clock components in laboratories, aerospace and navigation fields.

- High Insulation & Purity: High volume resistivity (≥1.0×10¹⁶ Ω·cm), excellent dielectric strength, isolating internal and external static and interference; minimal volatile content, no harmful residues, ensuring the cleanliness of atomic clock internal precision components.
- Precision Curing & Easy Operation: Adjustable weight mixing ratio, easy to proportion and stir; curable at room or heated temperatures, fully cured in 24 hours; optional vacuum degassing (0.01MPa for 3 minutes) to eliminate air bubbles, ensuring full penetration into tiny gaps of precision components.
- Strong Adhesion & Customizability: Excellent adhesion to PC, PMMA, PCB, aluminum, copper and stainless steel, ensuring tight sealing of atomic clock components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and interference resistance to match different atomic clock 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 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 affect timekeeping precision.
- 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 atomic clock precision 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.
