Product Overview
Our Electronic Potting for Reed Switch Assemblies is a professional Silicone Potting Compound developed for the encapsulation, sealing, contact protection and insulation of Reed Switch Assemblies. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for reed switch assemblies’ core needs—contact sensitivity retention, anti-magnetic interference and mechanical damage prevention. Unlike ordinary potting silicones, it is non-magnetic, does not interfere with reed switch magnetic sensing, cures without shrinkage, does not affect contact switching sensitivity, effectively isolates moisture, dust and external impact, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and reed switch metals, protecting internal contacts and wires, ensuring long-term stable switching performance for procurement partners.
Key Features & Advantages
1.Contact Sensitivity Protection & Anti-Magnetic Interference: Non-magnetic formula, no interference with the magnetic sensing performance of reed switches, ensuring accurate contact switching response; low modulus and non-shrinking curing, avoiding pressure on reed contacts, preventing contact jamming or poor contact, ensuring stable switching sensitivity and signal transmission.
2.Mechanical Damage Prevention & Dimensional Stability: Cures without shrinkage, maintaining precise dimensional compatibility with reed switch assemblies, not affecting their structural integrity and switching stroke; cured colloid is tough yet flexible, absorbing external impact and vibration, avoiding damage to fragile reed contacts and wires, extending assembly service life.
3.Superior Temperature Adaptability & Heat Dissipation: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; integrated thermally conductive potting compound properties efficiently dissipate slight heat generated by switch operation, avoiding overheating-induced contact oxidation and performance degradation; adapts to extreme industrial, automotive and outdoor temperature environments.
4.Strong Adhesion & Metal Protection: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, reed switch metals (nickel, iron, copper) and plastic housings, forming a tight seal without detachment; effectively resists corrosion and oxidation of metal contacts, preventing rust and contact 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 assembly production.
5.High Stability & Dual-Formula Options: Available in high-purity addition curing silicone (low volatility, non-toxic, high stability) and enhancedthermally conductive potting compound (for high-load reed switch assemblies), 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 switch components, which is crucial for contact sensitivity.
- 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, sealing and switching performance of reed switch assemblies.
- 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 reed switch assembly packaging molds or casings, avoiding overflow that affects contact switching.
- Curing: Place the encapsulated reed switch assembly 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 performance.
