FAQ
Electrical potting is the process of encapsulating electronic components in a protective material—such as epoxy, urethane, or silicone—to shield them from moisture, dust, vibration, and other environmental hazards.
Potting enhances the durability and reliability of electronic assemblies by preventing short circuits, corrosion, and mechanical damage. It also helps with thermal management and can improve product lifespan.
Common potting materials include epoxies (for high strength and thermal resistance), urethanes (for flexibility and low-temperature performance), and silicones (for high-temperature and moisture resistance).
The best material depends on your application’s requirements—such as operating temperature, exposure to chemicals or moisture, cure time, and mechanical stress. Consulting with a materials expert can help you select the ideal formulation.
