Conformal coating is a protective chemical layer applied to electronic components to shield them from environmental factors such as moisture, dust, chemicals, and temperature extremes. This thin, insulating coating conforms to the shape of the components, providing a barrier that enhances the reliability and longevity of the electronics. Common materials used for conformal coatings include acrylics, silicones, polyurethanes, and epoxies. The application methods can vary, including brushing, spraying, dipping, or automated selective coating. Conformal coatings are widely used in industries where electronic components are exposed to harsh conditions, such as automotive, aerospace, and consumer electronics.
