Silicone potting for electronics is a condensation polymer that is obtained through polymerization reactions. Its main features are great stability, chemically inert, good flexibility, good electrical insulator, water repellent, good dissipation heat, long service life in harsh environments, exceptional heat resistance and allows rework, and melting the old resin when reapplied.
In the electronics industry it is commonly used for boards that need heat dissipation, rework and will be exposed to high temperatures. It is indicated to protect products against water, heat, noise, vibration and to help cool down integrated circuit boards. It keeps stable properties between -40 to 392°F (-40 to 200°C).
