Product Overview
Our Electronic Potting for Thermal Cutoff Devices is a professional Silicone Potting Compound developed for the encapsulation, sealing, temperature protection and insulation of Thermal Cutoff Devices. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for thermal cutoff devices’ core needs—temperature response precision retention, high temperature resistance and flame retardancy. Unlike ordinary potting silicones, it has excellent high-temperature stability, does not affect the device’s thermal response threshold, cures without shrinkage, resists high-temperature aging and corrosion, and has excellent adhesion to PC, PMMA, PCB and device metals, protecting internal components, ensuring reliable overheat protection performance for procurement partners.
Key Features & Advantages
1.Temperature Response Precision Protection: High-temperature stable formula, no interference with the thermal response threshold of thermal cutoff devices, ensuring accurate activation at the set temperature, avoiding false triggering or failure; excellent thermal conductivity helps rapid heat transfer, ensuring the device responds timely to overheat risks, providing reliable protection for electronic systems.
2.Superior High Temperature Resistance & Flame Retardancy: Operating stably from -60℃ to 220℃, with outstanding high-temperature resistance, no curing failure or performance degradation in high-temperature environments; flame-retardant formula meets international safety standards, effectively preventing fire spread, reducing potential safety hazards of thermal cutoff devices in extreme conditions.
3.Ultra-High Insulation & Heat Dissipation: Integrated thermally conductive potting compound properties efficiently dissipate heat, avoiding overheating accumulation; ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), effectively isolating internal circuits, preventing leakage and short circuits, ensuring safe operation of thermal cutoff devices.
4.Strong Adhesion & Corrosion Resistance: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, thermal cutoff device metals (copper, stainless steel) and plastic housings, forming a tight seal without detachment; resistant to high-temperature aging, ozone and chemical erosion, avoiding material degradation and device failure; two-component design, easy to mix evenly, optional vacuum defoaming (0.01MPa for 3 minutes), supports room temperature or heated curing, full curing in 24 hours, suitable for batch production.
5.High Stability & Dual-Formula Options: Available in high-purity addition curing silicone (low volatility, non-toxic, high stability) and enhanced thermally conductive potting compound (for high-heat thermal cutoff devices), meeting different application needs; low volatility, high strength, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, reducing waste and procurement costs.
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, insulation and adhesion to device components, which is crucial for temperature response precision.
- 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, heat dissipation and temperature response performance of thermal cutoff devices.
- 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 cutoff device packaging molds or casings, avoiding overflow that affects thermal response.
- Curing: Place the encapsulated thermal cutoff device at room temperature for curing 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 high-temperature performance.
