It cures at room or heated temperatures, adheres well to PC, PP, ABS, PVC and metals, protecting QKD core components, ensuring signal integrity, complying with EU RoHS, and supporting full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting Compound (HY-9315) is specially developed for Quantum Key Distribution (QKD) systems, dedicated to encapsulating, sealing, thermally conducting and insulating QKD core components, quantum signal modulators, encryption modules, PCB substrates and power units. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for QKD scenarios, enhancing ultra-low electromagnetic interference and high insulation to adapt to the ultra-high precision, low-noise requirements of quantum encryption systems. Compared with epoxy potting resin, it has low viscosity, excellent flowability, no exotherm during curing, and IP65 waterproof grade, ensuring long-term reliable protection for QKD components and reducing signal interference.
Key Features & Advantages
- Ultra-Low Electromagnetic Interference: Optimized formula with minimal electromagnetic permeability, avoiding interference with quantum signal transmission and encryption integrity, ensuring stable operation of QKD systems and secure key distribution.
- Excellent Thermal Conductivity & Heat Dissipation: Thermal conductivity ≥0.8 W(m·K), efficiently transferring heat generated by QKD electronic components, avoiding overheating-induced signal distortion, and extending component service life.
- High Flame Retardancy & Waterproof Performance: Flame retardancy meets UL94-V0 standard, ensuring safe operation; IP65 waterproof and dustproof grade, effectively isolating moisture and dust, adapting to complex indoor and outdoor QKD deployment environments.
- Low Viscosity & Flexible Curing: Low viscosity (500±100 cps) with good flowability, penetrating tiny gaps of QKD components; 1:1 weight ratio, easy to operate; cures at room (4-5 hours) or 80℃ (20 minutes), fully cured in 8 hours at room temperature, improving production efficiency.
- Strong Adhesion & Customizability: Excellent adhesion to PC, PP, ABS, PVC and metals; as a professional Silicone Potting Compound manufacturer, we customize hardness (15±5 Shore A), viscosity, operation time (0.5-2 hours) and thermal conductivity to match different QKD system models.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A and Component B in their respective containers to ensure uniform mixing, avoiding stratification that affects thermal conductivity and signal compatibility.
- Precision Mixing: Strictly follow the 1:1 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 0.08MPa for 5 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of QKD components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature (4-5 hours basic curing) or 80-100℃ (15 minutes) for faster curing. Note: Curing time extends for thick applications; winter curing is recommended to be heated.
