VCI is an abbreviation for Vapor Corrosion Inhibitor or Volatile Corrosion Inhibitor.

(Also known as VpCI’s or Vapor Phase Corrosion Inhibitors.) These corrosion inhibiting compounds are coated on paper or polyethylene bags and have sufficient vapor pressure to release molecules into the air.

Due to their polarity, the VCI molecules are attracted to the surface of metal, just like a magnet. VCI molecules move from the paper or film directly to the surface of metals.

When these compounds come in contact with metal surfaces, they form a very thin molecular layer of protection. This thin layer effectively inhibits corrosion on the metal surface by preventing air VCI Products and moisture from coming in contact with the surface of the metal. Proper VCI packaging products work well in both the contact and vapor phase. This means that they provide protection against corrosion whether the metal is in direct contact with the VCI, or if it is merely in close proximity to the VCI. Unlike other methods of rust prevention, these corrosion inhibiting vapors have the ability to reach into intricate, recessed surfaces that would be otherwise hard to reach with traditional rust prevention products such as oils and greases.
