Product Overview
This high-isolation voltage potting silicone is classified into addition curing and condensation curing types, serving as a core protective Thermally Conductive Potting Compound for high-voltage electronic devices. It provides excellent sealing, filling and pressure resistance for PCB, CPU, PC and PMMA materials. After curing, it forms a dense dielectric protective layer, blocking high-voltage breakdown paths, absorbing thermal cycle stress, and protecting internal chips and gold bonding wires in extreme voltage environments.
Core Product Features & Advantages
Optimized for high isolation voltage working conditions, the product boasts exclusive insulation and comprehensive protective advantages:

2. All-round protective performance: Integrates waterproof, moisture-proof, dust-proof, anti-corrosion and shockproof functions, with excellent resistance to ozone and chemical erosion.
3. Extreme temperature adaptability: Stably operates at -60℃ to 220℃, relieves high-temperature thermal stress and maintains stable insulation performance in long-term temperature cycling.
4. Reliable adhesion & low volatility: Features low volatile content and high structural strength, firmly bonding aluminum, copper, stainless steel and circuit board substrates without performance degradation.
Application Scenarios
It is widely used for encapsulation and insulation protection of high-voltage power modules, high-voltage PCB boards, power supply components and industrial high-voltage control devices. Suitable for new energy electronics, industrial power equipment and high-voltage intelligent devices. It greatly reduces high-voltage failure risks, improves equipment safety stability, extends service life and cuts manufacturers’ maintenance and replacement costs.
Step-by-Step Usage Process
1. Pre-stirring: Fully stir component A to evenly disperse settled fillers and shake component B thoroughly before mixing.
2. Proportional mixing: Strictly follow standard AB component weight ratio to ensure uniform mixing and stable insulation performance.
3. Vacuum defoaming: Place mixed silicone in a 0.01MPa vacuum container for 3 minutes defoaming to avoid bubble defects affecting voltage insulation.
4. Curing treatment: Adopt room temperature or heating curing. The product can proceed to subsequent processes after initial curing, with full curing completed within 24 hours.

FAQ
Q1: Can it maintain stable insulation under long-term high voltage? A: Yes. Its dense cured structure and stable material properties sustain excellent isolation performance, resisting high-voltage breakdown and aging.
Q2: Does colloidal stratification affect insulation performance? A: Slight stratification is normal after long storage. Even stirring will not damage its high-isolation voltage and protective properties.
Q3: How to store high-voltage potting silicone? A: Keep sealed and stored in dry environment. Mixed glue must be used up at one time to avoid performance attenuation.
