Product Overview
Our Electronic Potting for Bimetallic Thermostats is a professional Silicone Potting Compound developed for the encapsulation, sealing, temperature control protection and insulation of Bimetallic Thermostats. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for bimetallic thermostats’ core needs—temperature control precision retention, efficient heat conduction and thermal cycle stability. Unlike ordinary potting silicones, it has excellent thermal conductivity and low modulus, does not interfere with the bimetallic strip’s thermal expansion and contraction, cures without shrinkage, resists high-temperature aging and corrosion, and has excellent adhesion to PC, PMMA, PCB and thermostat metals, protecting internal bimetallic components, ensuring reliable temperature control performance for procurement partners.
Key Features & Advantages
1.Temperature Control Precision Protection: Low modulus and thermally conductive formula, no interference with the bimetallic strip’s thermal expansion and contraction, ensuring accurate temperature switching at the set threshold, avoiding temperature deviation or false triggering; excellent thermal conductivity facilitates rapid heat transfer between the thermostat and the environment, ensuring timely response to temperature changes and stable temperature control.
2.Superior Temperature Stability & Thermal Cycle Resistance: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance, no curing failure or performance degradation in repeated thermal cycles; the cured colloid can absorb stress caused by thermal expansion and contraction, protecting the bimetallic strip from fatigue damage, extending the thermostat’s service life.
3.Ultra-High Insulation & Efficient Heat Dissipation: Integrated thermally conductive potting compound properties efficiently dissipate excess 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 bimetallic thermostats.
4.Strong Adhesion & Corrosion Resistance: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, bimetallic thermostat metals (copper, nickel, stainless steel) and plastic housings, forming a tight seal without detachment; resistant to high-temperature aging, ozone and chemical erosion, avoiding material degradation and thermostat 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 bimetallic thermostats), 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)
1.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 thermostat components, which is crucial for temperature control precision.
2.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 conduction and temperature control performance of bimetallic thermostats.
3.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 bimetallic thermostat packaging molds or casings, avoiding overflow that affects bimetallic strip movement.
4.Curing: Place the encapsulated bimetallic thermostat 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 thermal performance.
