Product Overview
Our Electronic Potting for Mercury Wetted Relays is a professional Silicone Potting Compound developed for the encapsulation, insulation, corrosion protection and shock absorption of Mercury Wetted Relays. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for mercury wetted relays’ core needs—stable insulation, corrosion resistance, temperature stability and protection of metal contacts. Unlike ordinary potting silicones, it has excellent anti-ozone and chemical erosion resistance, can absorb stress from high-temperature cycles, protect internal mercury contacts and welding gold wires, ensure stable switching performance, and bring reliable protection for procurement partners.
Key Features & Advantages
- Superior Temperature Stability & Stress Absorption: Operates stably from -60℃ to 220℃, with excellent high and low temperature resistance; can absorb stress caused by internal high-temperature cycles of mercury wetted relays, avoiding damage to mercury contacts, chips and welding gold wires, ensuring long-term stable operation in extreme temperature environments.
- Ultra-High Insulation & Corrosion Resistance: Outstanding insulation performance, effectively isolating internal circuits of mercury wetted relays, preventing leakage and short circuits; excellent anti-ozone and chemical erosion resistance, resisting corrosion from external substances, protecting mercury contacts from oxidation, and maintaining excellent electrical conductivity.
- Strong Adhesion & Wide Compatibility: High bonding strength to copper, stainless steel, aluminum and other metals (key for mercury wetted relay contacts), as well as PC, PMMA and PCB; forms a tight seal without detachment, avoiding gaps that lead to moisture or dust intrusion, ensuring comprehensive protection.
- Low Volatility & High Strength: Low volatility, no harmful substances released during curing, ensuring the safety of mercury wetted relay internal components; cured colloid has high strength, good shock absorption, reducing damage caused by external vibration, protecting fragile internal structures.
- Dual-Formula Options & Customization: Available in high-performance addition curing silicone (low volatility, high stability) and enhanced Thermally Conductive Potting Compound (for high-power mercury wetted relays); parameters such as hardness, viscosity and operation time can be customized to meet different production needs.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect, adhesion and insulation performance of mercury wetted relays.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which may affect insulation and protection of internal mercury contacts.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then pour it into mercury wetted relay casings, ensuring full infiltration of all components.
- Curing: Place the encapsulated mercury wetted relay at room temperature or heat to accelerate curing; enter the next process after basic curing, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed and final performance.
