Product Overview
Our Electronic Potting Silicone is specially developed for hydrogen fuel stack monitors, dedicated to encapsulating, sealing, insulating and fixing their core electronic modules, sensor units, signal transmission components and PCB boards. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for hydrogen fuel stack scenarios, enhancing hydrogen corrosion resistance and thermal conductivity to adapt to high-temperature, hydrogen-rich working environments. Compared with epoxy potting resin, it has better flexibility and low viscosity, enabling deep penetration into tiny gaps, supports fast room-temperature curing, and ensures long-term reliable protection for monitor components, reducing equipment failure rates and maintenance costs for hydrogen energy manufacturers.
Key Features & Advantages
- Excellent Hydrogen Corrosion Resistance: Optimized formula resistant to hydrogen permeation and corrosion, avoiding material degradation in hydrogen-rich environments, ensuring stable performance of hydrogen fuel stack monitor components for long-term use.
- High Thermal Conductivity: Thermal conductivity ≥0.4 W(m.k), effectively dissipating heat generated by monitor operation and fuel stack working temperature, protecting electronic components from thermal damage.
- Fast Room-Temperature Deep Curing: Low-viscosity formula, 1:1 weight mixing ratio, easy to operate; achieves deep curing at room temperature, basic curing in 3-5 hours and full curing in 12-24 hours, improving production efficiency.
- Superior Adhesion & Insulation: Excellent bonding to PC, PP, ABS, PVC and metals, ensuring tight sealing; dielectric strength ≥25 KV/mm, volume resistivity ≥1.0×10¹⁶ Ω.cm, providing reliable insulation for monitor circuits.
- Compliance & Customizability: Fully complies with EU RoHS directive, non-toxic and environmentally friendly; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity, operation time and thermal conductivity to match different hydrogen fuel stack monitor 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 adhesion and corrosion resistance.
- 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.
- Degassing: After mixing, place the adhesive in a vacuum container at 0.08MPa for 3 minutes to eliminate air bubbles, ensuring full penetration into tiny gaps of monitor components.
- Curing: Pour the degassed mixture into component housings; cure at room temperature, enter the next process after basic curing (3-5 hours), and ensure 12-24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed.
