VCIs: effectively combatting corrosion
When they come into contact with oxygen, all metals form a primary oxide layer which protects the metal underneath from corrosion. How stable this protection is, however, varies depending on the type of metal involved and the environmental conditions. If the primary oxide layer is damaged even slightly, the underlying metal will react with the elements in its vicinity and corrosive pitting sets in. The process can lead to the complete destruction of the metal and the potential for damage during shipment and storage is great.
Fortunately this outcome can be averted through the use of volatile corrosion inhibitors (VCIs), substances which slow the corrosive process virtually to a standstill. Provided the EXCOR VCI substances remain in the VCI packaging, the active corrosion protection can last for decades, even under extreme conditions.
