Product Overview
Our Electronic Potting for Micro Relay Coils is a professional Silicone Potting Compound developed for the encapsulation, sealing, insulation and anti-interference protection of Micro Relay Coils. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for micro relay coils’ core needs—insulation protection, anti-electromagnetic interference and thermal stability. Unlike ordinary potting silicones, it has ultra-high insulation and low dielectric loss, does not interfere with coil electromagnetic performance, cures without shrinkage, resists high-temperature aging and corrosion, and has excellent adhesion to PC, PMMA, PCB and coil metals (copper, enameled wire), protecting internal coils from damage, ensuring reliable switching performance for procurement partners.
Key Features & Advantages
1.Anti-Electromagnetic Interference & Coil Protection: Low dielectric loss and non-magnetic formula, no interference with the micro relay coil’s electromagnetic induction and switching performance, avoiding signal interference or misoperation; the cured colloid forms a tight protective layer, isolating external electromagnetic radiation, protecting enameled wires from wear and short circuits, ensuring stable coil operation.
2.Ultra-High Insulation & Leakage Prevention: Excellent insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), effectively isolating coil windings, preventing leakage and short circuits caused by moisture or dust; strong adhesion to enameled wire and coil substrates, avoiding gaps that lead to insulation failure, ensuring safe operation of micro relays.
3.Superior Temperature Stability & Heat Dissipation: Integrated thermally conductive potting compound properties efficiently dissipate heat generated by coil energization, avoiding overheating-induced enameled wire aging; operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance, no curing failure or performance degradation in extreme environments, adapting to industrial and automotive working conditions.
4.Anti-Vibration & Corrosion Resistance: Cured colloid is tough yet flexible, absorbing external vibration and impact, preventing coil loosening or enameled wire breakage; resistant to high-temperature aging, ozone and chemical erosion, avoiding material degradation and coil 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 of micro relays.
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-power micro relay coils), 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 coil components, which is crucial for anti-interference and insulation performance.
- 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 electromagnetic performance of micro relay coils.
- 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 micro relay coil packaging molds or casings, avoiding overflow that affects coil winding and switching performance.
- Curing: Place the encapsulated micro relay coil 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 insulation performance.
