conformal coating

Part of the Electronics glossary:

Conformal coating is the process of spraying a dielectric material onto a device component to protect it from moisture, fungus, dust, corrosion, abrasion, and other environmental stresses. Common conformal coatings include silicone, acrylic, urethane, epoxy, and Parylene. Parylene is a unique polymer conformal coating that conforms to virtually any shape including crevices, points, sharp edges, and flat, exposed internal surfaces.
