HONG YE SILICONE Electronic Potting Compound for High-Vibration Environments is a high-performance two-component Addition Curing Silicone, also known as Silicone Encapsulant and electronic Potting Compound, tailored for vibration-prone electronic components. Crafted from high-purity Silicone raw materials, it features adjustable weight mixing ratio, excellent shock absorption, temperature resistance (-60℃ to 220℃), and strong adhesion. It cures at room or heated temperatures, effectively buffers vibration impact, adheres well to PC, PCB and metals, protects components from damage, complies with EU RoHS, and supports full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting Compound is specially developed for High-Vibration Environments, dedicated to encapsulating, sealing, insulating and shock-absorbing electronic components, PCB assemblies, connectors and sensitive modules in vibration-intensive scenarios. As a leading manufacturer of liquid silicone and addition curing silicone, we optimize the formula for high-vibration working conditions, enhancing shock absorption, bonding strength and structural stability. Compared withepoxy potting resin, it has excellent flexibility, minimal volatile content, no exotherm during curing, and low shrinkage, effectively absorbing vibration energy and avoiding damage to fragile components.
Key Features & Advantages
- Superior Shock Absorption & Vibration Resistance: High elasticity and excellent shock absorption performance, effectively absorbing vibration energy (up to 50Hz continuous vibration), reducing vibration impact on electronic components, protecting chips, welding gold wires and connectors from loosening or damage.
- Excellent Temperature & Environmental Stability: Stable performance from -60℃ to 220℃, withstanding extreme temperature fluctuations while resisting vibration; excellent resistance to ozone, oxidation and chemical erosion, adapting to harsh high-vibration industrial environments.
- Strong Adhesion & Wide Compatibility: Excellent adhesion to PC, PCB, aluminum, copper and stainless steel, tightly bonding components and substrates; no corrosion or damage to electronic parts, ensuring firm bonding even under long-term vibration, without peeling or detachment.
- 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 high-vibration industrial 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, elasticity and curing speed to match different vibration intensity 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 shock absorption and adhesion performance under vibration.
- 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 under vibration.
- 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 and tight bonding of vibration-prone 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 vibration resistance.
