Product Overview
Our Durable Electronic Potting Silicone Compound is a professional long-acting protective potting material for electronic components, a key part of HONG YE SILICONE’s full silicone product matrix. Also called potting glue, electronic glue or encapsulation silicone, it cures into a high-strength, corrosion-resistant protective layer after mixing with curing agent. Different from ordinary Electronic Potting Compound, it is optimized for durability—withstands extreme temperatures, chemical erosion and long-term environmental aging, providing all-round, long-lasting protection for electronic components and solving the pain points of frequent component failure due to insufficient durability. Product Features & Advantages
1. Superior long-term durability: Excellent anti-aging, anti-ozone and anti-chemical erosion performance, maintains stable performance after long-term use, effectively extending the service life of electronic components and reducing after-sales costs.
2. Extreme temperature durability: Operates stably from -60℃ to 220℃, absorbs stress caused by high-temperature cycles, protects chips and welding gold wires, adapting to severe cold, high-heat and temperature-fluctuating environments.
3. All-round durable protection: Integrates waterproof, moisture-proof, dust-proof, insulation, thermal conductivity, shockproof and anti-corrosion properties, forming a dense protective barrier to isolate components from external damage.
4. High strength & strong adhesion: Low volatile content, high curing strength, excellent adhesion to PC, PMMA, PCB, CPU and metals (aluminum, copper, stainless steel), no peeling or cracking after long-term use.
5. Flexible curing &量产-friendly: Addition curing type, supports room-temperature (full curing 24h) or heating curing, with stable curing effect; optional vacuum defoaming, easy to operate, adapting to automated production lines.
6. Stable & reliable performance: Curing process is stable, not easily affected by ambient temperature and humidity (with slight impact that can be adjusted), ensuring consistent quality of each batch for bulk production.
Technical Specifications
This product is a two-component durable electronic potting silicone compound, available in addition and condensation curing types. Both Component A and B are liquid, requiring thorough stirring before mixing according to the specified weight ratio. It operates stably at -60℃ to 220℃, with excellent adhesion and thermal conductivity. Key parameters including cured hardness, viscosity, operable time, curing speed and thermal conductivity can be fully customized according to customers’ specific application needs; detailed parameters of specific models are available on request.
How to Use
1. Preparation: Fully stir Component A to mix settled fillers evenly; shake Component B thoroughly to ensure uniform material composition without stratification, critical for durable bonding and curing effect.
2. Mixing: Blend Component A and B strictly according to the specified weight ratio, stir thoroughly to guarantee consistent durability, thermal conductivity and insulation performance.
3. Deaeration (Optional): Place the uniformly mixed glue into a vacuum container, deaerate for 3 minutes under 0.01MPa to remove air bubbles, ensuring a dense, durable protective layer.
4. Potting & Curing: Pour the treated silicone onto target components; cure at room temperature or by heating. Proceed to the next process after basic curing, and ensure 24 hours for full curing to achieve optimal durability.
Application Scenarios
Widely used for encapsulation, sealing, filling and pressure protection of electronic components, including PCB, CPU, LED modules, outdoor LED displays, power modules and general electrical modules. It is suitable for electronic manufacturing, LED lighting, automotive electronics, industrial control and outdoor electronic industries, providing long-term durable protection, reducing component failure rates and after-sales costs, and enhancing the market competitiveness of customers’ products.
