The VCI active ingredient (VCI = Volatile Corrosion Inhibitor) can be a component of different packaging materials, such as film or paper. It vaporises from these into the packaging space, condenses on the bare metal surfaces and thus prevents ambient molecules – such as water or oxygen – from reacting with the metal, so forming a temporary, dry corrosion protection.
After removal of the packaging, the inhibitors volatilise leaving no residues. This is also the main advantage of VCI corrosion protection when compared to protective layers involving oils or waxes, which have to be removed at great expense. Depending on the structure and handling of the packaging, our VCI packaging is guaranteed to provide corrosion protection for up to 15 years.
