Product Overview
Our customized potting silicone is exclusively developed for interdigital capacitor encapsulation, acting as a high-stability Electronic Potting Compound and flexible Silicone Encapsulant. This two-component liquid silicone cures into a soft, stress-free protective layer after AB component mixing. It effectively solves core pain points of interdigital capacitors such as moisture intrusion, thermal fatigue, electric leakage and mechanical pressure damage, stabilizing capacitance accuracy and prolonging component service life.
Core Product Features & Advantages
1. Precision full protection: Integrates waterproof, moisture-proof, dust-proof, anti-corrosion, insulation and shockproof functions to shield delicate interdigital electrode structures from external interference.
2. Wide temperature adaptability: Stably operates from -60℃ to 220℃, absorbs thermal cycling stress, and protects capacitor chips and gold welding wires without affecting electrical stability.
3. Low volatility & strong adhesion: Ultra-low volatile content avoids micro contamination; firmly bonds with PCB, PMMA, CPU and multiple metals including aluminum and copper for long-term reliable sealing.
4. Superior chemical resistance: Resists ozone and chemical erosion, slowing component aging, reducing failure rates and cutting manufacturers’ replacement costs.
5. Flexible customizable performance: Adjustable viscosity, hardness, operation time and curing time to match diverse interdigital capacitor sizes and automated precision production lines.
Step-by-Step Usage Instructions
1. Pre-preparation: Fully stir Component A evenly to homogenize precipitated fillers and shake Component B thoroughly before mixing.
2. Proportional mixing: Mix A and B components strictly per standard weight ratio and stir uniformly to ensure consistent curing performance.
3. Vacuum defoaming: Place mixed silicone in a 0.01MPa vacuum container for 3 minutes to eliminate bubbles for flawless precision encapsulation.
4. Curing process: Cure via room temperature or heating mode; achieve initial curing for subsequent processes, with full curing completed within 24 hours. Ambient temperature and humidity significantly affect curing speed.
