VCI technology works to create a protective environment within each package or enclosure where it is applied. VCIs inside liquids, powders, or packaging materials travel through the air to form an invisible protective shield on metal surfaces in the enclosed space. This VCI shield does not alter metal properties. Instead, it blocks the ability of oxygen, moisture, and other corrosive elements to attack the metal surface and make it rust. After the metal part is taken out of the VCI packaging or enclosed space, the VCIs float away, and the metal components, machinery, or products are ready for immediate use, no cleaning or degreasing required.
