In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents. Thermo-setting plastics or silicone rubber gels are often used. Many sites recommend using silicone or epoxy to protect from impact and loose wires. Araldite (a brand name) potting compound has been suggested for certain automotive applications.
