Product Overview
Our Electronic Potting for Mercury Tilt Switches is a professional Silicone Potting Compound developed for the encapsulation, sealing, mercury protection and insulation of Mercury Tilt Switches. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for mercury tilt switches’ core needs—mercury leakage prevention, tilt triggering sensitivity retention and corrosion resistance. Unlike ordinary potting silicones, it has excellent sealing performance, effectively isolating mercury from the external environment, cures without shrinkage, does not affect the tilt triggering stroke, resists corrosion from mercury and external chemicals, and has excellent adhesion to PC, PMMA, PCB and switch metals, protecting internal mercury and contacts, ensuring long-term stable tilt triggering performance for procurement partners.
Key Features & Advantages
1.Mercury Leakage Prevention & Sealing Performance: High-density curing formula with excellent airtightness, effectively sealing mercury inside the switch, preventing leakage that may cause environmental pollution and switch failure; tight adhesion to switch housings and metal contacts, forming a barrier against moisture, dust and external substances, ensuring safe and reliable operation.
2.Tilt Triggering Sensitivity Protection & Dimensional Stability: Low modulus and non-shrinking curing, avoiding pressure on the switch internal structure, not affecting the mercury flow and tilt triggering sensitivity; maintains precise dimensional compatibility with mercury tilt switches, ensuring accurate triggering response to different tilt angles, no false triggering or failure.
3.Superior Temperature Adaptability & Heat Dissipation: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance, no curing failure or performance degradation in extreme temperatures; integrated thermally conductive potting compound properties efficiently dissipate slight heat, avoiding mercury volatilization or switch damage caused by overheating, adapting to industrial, automotive and outdoor environments.
4.Corrosion Resistance & Strong Adhesion: Excellent resistance to mercury corrosion and chemical erosion, no reaction with mercury or switch materials (metal, plastic), avoiding material degradation and switch failure; strong adhesion to PC (electronic insulation board), PMMA (acrylic), PCB, switch metals (copper, stainless steel) and plastic housings, no detachment or cracking; 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-load mercury tilt switches), 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, sealing performance and adhesion to switch components, which is crucial for mercury leakage prevention and triggering sensitivity.
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 sealing, insulation and tilt triggering performance of mercury tilt switches.
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 mercury tilt switch packaging molds or casings, avoiding overflow that affects mercury flow and triggering.
4.Curing: Place the encapsulated mercury tilt switch 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 sealing performance.
