Potting compounds protect and insulate electronics and electrical components from environmental conditions. Potting is the process of filling the base of an electronic assembly with adhesive to provide permanent stability and protection against moisture, heat, vibration, and corrosion. They are used for electronic assemblies in commercial electronic, automotive, and aerospace industries.

Protective coatings cover surfaces to safeguard components from corrosion, chemicals, and abrasion. They differ from potting compounds because they don't offer electrical insulation and must be brushed on to components. They provide relief to worn surfaces and protect equipment that is exposed to impact.
