Product Overview
Our Electronic Potting for Wirewound Pots is a professional Silicone Potting Compound developed for the encapsulation, sealing, wire protection and insulation of Wirewound Pots (wirewound potentiometers). As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for wirewound pots’ core needs—ultra-high insulation, wear resistance and wire corrosion protection. Unlike ordinary potting silicones, it cures without shrinkage, does not affect the rotation smoothness of wirewound pots, effectively isolates moisture and dust, resists corrosion and ozone, and has excellent adhesion to PC, PMMA, PCB and metal wires, protecting internal windings and conductive components, ensuring long-term stable resistance adjustment for procurement partners.
Key Features & Advantages
- Ultra-High Insulation & Wire Protection: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), effectively isolating internal windings and circuits, preventing short circuits caused by wire aging; excellent adhesion to metal wires (copper, aluminum, stainless steel), forming a protective layer to avoid wire corrosion and breakage, extending wirewound pot service life.
- Wear Resistance & Dimensional Stability: Cures without shrinkage, maintaining precise dimensional compatibility with wirewound pots, not affecting rotation smoothness and resistance adjustment accuracy; cured colloid has high hardness and wear resistance, resisting friction caused by potentiometer rotation, avoiding colloid damage and performance failure.
- 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 heat generated by wirewound pot current, avoiding overheating-induced resistance drift and component damage; adapts to extreme industrial temperature environments.
- Strong Adhesion & Easy Operation: Excellent adhesion to PC (electronic insulation board), PMMA (acrylic), PCB and various metals, forming a tight seal without detachment; 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 wirewound pot production.
- 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-current wirewound pots), meeting different load and 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 wire adhesion, which is crucial for wirewound pot stability.
- 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 rotation smoothness of wirewound pots.
- 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 wirewound pot packaging molds or casings, avoiding overflow that affects rotation adjustment.
- Curing: Place the encapsulated wirewound pot 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.
