Product Overview
Our Electronic Potting for Thermal Relay Elements is a professional Silicone Potting Compound developed for the encapsulation, insulation, heat dissipation and shock absorption of Thermal Relay Elements. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for thermal relay elements’ core needs—efficient heat dissipation, stable insulation, temperature stability and protection of heating components. Unlike ordinary potting silicones, it integrates excellent thermal conductivity and temperature resistance, can absorb stress from high-temperature cycles, protect internal heating elements and welding points, ensure accurate thermal sensing and overload protection 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 thermal relay elements, avoiding damage to heating components, chips and welding points, ensuring long-term stable thermal sensing performance in extreme temperature environments.
- Efficient Thermal Conductivity & Heat Dissipation: Integrated Thermally Conductive Potting Compound properties, efficiently dissipate heat generated by thermal relay elements during operation, avoid overheating-induced performance degradation or damage, ensure accurate overload protection, and extend the service life of thermal relay elements.
- Ultra-High Insulation & Corrosion Resistance: Outstanding insulation performance, effectively isolating internal circuits of thermal relay elements, preventing leakage and short circuits; excellent anti-ozone and chemical erosion resistance, resisting corrosion from external substances, protecting metal contacts and heating elements from oxidation, maintaining stable electrical and thermal performance.
- Strong Adhesion & Wide Compatibility: High bonding strength to copper, aluminum, stainless steel and other metals (key for thermal relay heating elements and 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 & Customizable Parameters: Low volatility, no harmful substances released during curing, ensuring the safety of thermal relay internal components; cured colloid has high strength and good shock absorption, reducing damage caused by external vibration; parameters such as hardness, viscosity, thermal conductivity 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, thermal conductivity and insulation performance of thermal relay elements.
- 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 heat dissipation and insulation of internal heating components.
- 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 thermal relay element casings, ensuring full infiltration of all components.
- Curing: Place the encapsulated thermal relay element 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 thermal conductivity performance.
