The action of VCI on metal surfaces is follows the following mechanism of action:

> Closing the package containing Volatile Inhibitor (VCI);

> Volatilization of VCI;

> Confined atmosphere containing the VCI;

> Migration of VCI for every cavity and place of the metal part;

> Condensation of VCI on the metal surface;

> Absorption of VCI on the metal surface;

> Monomolecular layer formation on the metal surface;

> Neutralization of current (previous) corrosion;

> Saturation with the VCI (equilibrium).
