How VCI Works
Corrosion inhibitor compounds vaporize from the paper or film. They
are attracted to the charged surface of the metal by virtue of their
The VCI molecules align on the surface of the metal to a depth
of 3 to 5 molecules. This layer of molecules passivates the charged
surface and creates a barrier that prevents oxidation. The corrosion
cell (the flow of electrons in the metal and the flow of ions in
the electrolytic surface layer) is unable to establish itself. Corrosion
Airtight packing is not required!
Simply store or ship metal parts in VCI packaging. When the parts
are unwrapped, the protective layer immediately begins to dissipate.
The metal parts are clean, corrosion-free and ready to use. No washing,
dipping or cleaning is necessary.
