Corrosion Inhibitors

Corrosion inhibitors are a group of chemicals that provide a barrier layer between metal surfaces and the atmosphere for the purpose of delaying oxidation. Metal oxidation also known as corrosion or rust will degrade the mechanical integrity of a metal. Preventing corrosion is necessary for the long term performance of any non-noble metal, such as aluminum, brass, copper, steel & zinc. To select the best corrosion inhibitor for your application, please provide the following information:

  • The metal that needs to be protected
  • Type of parts – geometry and application
  • The amount of corrosion protection required – salt spray hours
  • How the corrosion inhibitor will be applied – immersion, spray, wipe-on
  • Surface finish required – oily, dry-to-touch, etc.
  • Any specification requirements


Corrosion inhibitors come in many forms:

  • Oils – water based and solvent based
  • Lacquers – water based and solvent based
  • VCI – Vapor Corrosion Inhibitors for packaging
  • Amines
  • Molybdates
  • Phosphates
  • Sacrificial plated deposits – zinc and cadmium
  • Chromates, Silicates, Organo-Mineral Sealers
