In the rapid development of the electronics industry, in order to ensure the stability and reliability of components and complete machines, potting technology has become a key link. Through potting, electronic components and assembly parts can be effectively protected from the erosion of moisture, impurities, and chemical atmosphere in the atmosphere, ensuring that electronic devices can stably perform their normal electrical functions. Vinyl silicone oil has emerged as a key material for protecting and improving the performance of electronic products.

Vinyl silicone oil provides a strong protective film for electronic components and assembly parts with its excellent performance. This protective film can effectively isolate moisture, impurities, and other chemicals in the atmosphere, preventing them from contaminating and eroding electronic devices. Through potting treatment, vinyl silicone oil ensures that electronic devices can operate stably under various environmental conditions and perform their normal electrical functions.
(1) Strict requirements for electronic component potting materials
When selecting potting materials for electronic components, a series of stringent requirements must be met, including excellent electrical properties, good insulation, excellent mechanical properties, high strength, and good elasticity. In addition, the viscosity of the potting material should be as low as possible and the fluidity should be good to facilitate the potting operation.
(2) Refining and performance improvement of vinyl silicone oil To ensure the electrical insulation of potting adhesive, the water content and ionic content of vinyl silicone oil must be controlled at a low level. Research has shown that refining vinyl silicone oil with adsorbents can significantly improve the electrical properties of potting adhesive.
(3) Selection and application of vinyl silicone oil When selecting vinyl silicone oil, the appropriate type is usually chosen based on the specific application requirements. End-vinyl silicone oil is often selected to ensure good fluidity and mechanical properties of potting compounds due to its low viscosity characteristics. Side-chain vinyl silicone oil, with its more dense cross-linking points, can provide superior mechanical properties and is suitable for applications with higher mechanical performance requirements.
