VCI INFO
A Vapor Corrosion Inhibitor is a class of chemical compounds which emit a rust-inhibiting vapor in the air to inhibit corrosion on a metal surface. VCI chemicals are usually carried in a packaging material such as paper or poly film. VCIs typically eliminate the need for oils and liquid rust preventatives, and protect the metal surface from rust.
Oxidation occurs when an electrolyte (water, oxygen, etc.) is present on the surface of a metal. The corrosion process begins when electrons flow through the electrolyte from high energy areas to low energy areas of the metal. VCI Technology blocks this reaction by passivating the surface and inhibiting the electrochemical current flow from high energy areas to low energy areas. VCI’s protective vapors attach themselves to a metal surface to form an invisible film only a few molecules thick to protect metal from attack.
