HONG YE SILICONE Electronic Potting Compound for Strapdown Inertial Navigation (SINS) is a high-stability two-component Addition Curing Silicone, also known as Silicone Encapsulant and Electronic Encapsulation Adhesive, tailored for SINS equipment. Crafted from high-purity Silicone raw materials, it features adjustable weight mixing ratio, low viscosity, strong anti-vibration, and temperature adaptability (-60℃ to 220℃). It cures at room or heated temperatures, adheres well to PC, PMMA, PCB and metals, protects core SINS components, ensures precise navigation data, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting Compound is specially developed for Strapdown Inertial Navigation (SINS) systems, dedicated to encapsulating, sealing, insulating and protecting SINS gyroscopes, accelerometers, signal processing modules, PCB substrates, and data transmission components. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for high-precision navigation scenarios, enhancing anti-vibration, low interference and environmental adaptability to adapt to the ultra-high-precision, harsh environment requirements of SINS. Compared with epoxy potting resin, it has minimal volatile content, excellent temperature adaptability, no exotherm during curing, and absorbs vibration/thermal stress, ensuring long-term reliable operation of SINS components in complex navigation environments.
Key Features & Advantages
- Excellent Anti-Vibration & Stability: Optimized formula with strong anti-vibration and shock resistance, effectively absorbing vibration and impact from vehicles, aircraft or ships, avoiding SINS component displacement and navigation data deviation, ensuring stable and precise navigation performance.
- Superior Temperature Adaptability & Stress Absorption: Stable performance from -60℃ to 220℃, withstanding extreme temperature fluctuations in aerospace, marine and ground navigation environments; effectively absorbing thermal and vibration stress, protecting SINS gyroscopes and accelerometers from damage.
- Low Signal Interference & High Insulation: Ultra-low electromagnetic interference, avoiding interference with SINS signal transmission and data calculation; high volume resistivity (≥1.0×10¹⁶ Ω·cm), excellent dielectric strength, isolating internal and external static and interference.
- Low Viscosity & Flexible Curing: Low viscosity, good fluidity, penetrating tiny gaps of SINS components and precision interfaces; 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 SINS components; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and curing speed to match different SINS 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 anti-vibration 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 interference and affect navigation 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 SINS 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.
