Product Overview
Our Electronic Potting Compound is specially developed for Extreme Temperature Ranges, dedicated to encapsulating, sealing, insulating and protecting electronic components, PCB assemblies, connectors and sensitive modules in ultra-high or ultra-low temperature environments. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for drastic temperature fluctuations, enhancing thermal stability, temperature resistance and stress absorption. Compared with epoxy potting resin, it has minimal volatile content, no exotherm during curing, low shrinkage, and good flexibility, avoiding cracking or peeling under extreme temperature cycles.
Key Features & Advantages
- Superior Extreme Temperature Resistance: Stable performance in a wide range of -60℃ to 220℃, withstanding continuous operation in ultra-low and ultra-high temperature environments; no performance degradation, cracking or brittle failure even under drastic temperature changes (from -60℃ to 220℃ in a short time).
- Excellent Thermal Stability & Stress Absorption: Effectively absorbs thermal stress caused by extreme temperature cycles, protecting chips, welding gold wires and delicate components from damage; low thermal expansion coefficient, ensuring structural stability of encapsulated components in temperature fluctuations.
- Strong Adhesion & Wide Compatibility: Excellent adhesion to PC, PCB, aluminum, copper and stainless steel, maintaining firm bonding even under extreme temperatures; no corrosion or damage to electronic parts, ensuring long-lasting encapsulation and protection.
- Low Volatility & High Safety: Ultra-low volatile content, no harmful residues or outgassing, avoiding contamination of sensitive electronic components; non-toxic, non-hazardous, complying with international environmental and safety standards, suitable for extreme temperature industrial and scientific applications.
- Easy Operation & Customizability: Adjustable weight mixing ratio, optional vacuum degassing (0.01MPa for 3 minutes), curable at room or heated temperatures, improving encapsulation efficiency; as a professional Silicone Potting Compound manufacturer, we customize hardness, viscosity and curing speed to match different extreme temperature requirements.
How to Use
- Pre-Mix Preparation: Thoroughly stir Component A to evenly distribute settled fillers, and shake Component B vigorously to ensure uniformity, avoiding stratification that affects thermal stability and adhesion under extreme temperatures.
- Precision Mixing: Strictly follow the recommended weight ratio of Component A to B, stirring slowly and evenly to ensure full integration without air bubbles that cause structural weaknesses and component damage in temperature cycles.
- Degassing (Optional): After mixing, place the adhesive in a vacuum container at 0.01MPa for 3 minutes to eliminate air bubbles, then pour it into components to ensure full coverage of core parts.
- Curing: Place the encapsulated components at room temperature or heat to accelerate curing; enter the next process after basic curing, and ensure 24 hours of full curing. Note: Environment temperature and humidity significantly affect curing speed and thermal stability.
