Product Overview
Our Electronic Potting for Magneto Resistive Elements is a professional Silicone Potting Compound developed for the encapsulation, sealing, precision protection and insulation of Magneto Resistive Elements. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for magneto resistive elements’ core needs—magnetoresistance property protection, electromagnetic interference resistance and signal stability. Unlike ordinary potting silicones, it is non-magnetic, does not interfere with the magnetoresistive effect of elements, cures without shrinkage, does not affect signal transmission precision, effectively isolates moisture, dust and external interference, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and element metal components, protecting internal magneto resistive structures, ensuring long-term stable signal output for procurement partners.
Key Features & Advantages
1.Magnetoresistance Property Protection & Anti-EMI: Non-magnetic formula, no interference with the magnetoresistive effect of magneto resistive elements, ensuring accurate signal response to magnetic field changes; ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), effectively isolating internal circuits and external electromagnetic interference, preventing signal distortion and short circuits.
2.High-Precision Signal Transmission & Dimensional Stability: Cures without shrinkage, maintaining precise dimensional compatibility with magneto resistive elements, not affecting their signal transmission speed and detection accuracy; cured colloid is soft yet tough, absorbing external vibration and impact, avoiding damage to fragile magneto resistive structures and ensuring consistent signal stability.
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 element operation, avoiding overheating-induced performance degradation and component damage; adapts to extreme industrial, automotive and outdoor temperature environments.
4.Strong Adhesion & Material Compatibility: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, element metals (aluminum, copper, nickel) and plastic housings, forming a tight seal without detachment; no chemical reaction with magneto resistive elements and their materials, avoiding material degradation and ensuring element service life; 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 element 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-load magneto resistive elements), 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 element components, which is crucial for signal transmission 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, sealing and signal stability of magneto resistive elements.
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 magneto resistive element packaging molds or casings, avoiding overflow that affects detection performance.
4.Curing: Place the encapsulated magneto resistive element 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.
