How Does VCI Work?

Corrosion begins when an electrolyte (water, oxygen, humidity) is present on the surface of a metal. When this happens, electrons then flow from high-energy areas of the metal to low energy areas in a loop, through the electrolyte. The corrosion process results in the formation of oxidation on the metal surface. Green Packaging’s VCI (Volatile Corrosion Inhibitors) slow or stop this reaction by passivating the surface and inhibiting or depressing the electro-chemical mechanism that triggers oxidation, i.e. the current flow from anode to cathode. Electrical current attempts to flow from the anode through the electrolyte into the cathode but cannot, because of the VCI's presence. Simply put your metal parts inside a Green Packaging, Inc. VCI poly bag, or wrap your parts in Green Packaging, Inc. VCI paper. The VCI chemistry migrates from the paper or poly and deposits on all of the metal surfaces of your parts. VCI molecules attach themselves to a metal surface to form an invisible, thin film, possibly only a few molecules or even one molecule thick, to protect metal from attack. Green Packaging’s VCI products can work for several years to prevent corrosion from occurring on the metal surface.

Remember, Green Packaging, Inc. carries a complete line of VCI paper, VCI poly bags, VCI poly sheeting, VCI emitters, VCI impregnated foams, VCI wire, VCI netting, VCI corrugated, and many other VCI devices for prevention of corrosion on virtually any type of metal.
