Industry manufacturers refer to VCIs as vapor corrosion inhibitors and volatile corrosion inhibitors. They are chemicals that protect the surface of metals from corrosion. Corrosion inhibitors are a class of substances that can prevent corrosion when you add them in small amounts.
Vapor Corrosion Inhibitors
VCI corrosion protection works by creating a thin film of molecular ions, which shields metal surfaces from the corrosive effects of moisture, air, and other substances. This invisible film acts as a barrier that prevents air, corrosive type environments, and moisture from coming into contact with the metal surface.
The metal part, which must be protected, is wrapped in a special VCI sheet, bag, paper or film that releases small amounts of VCIs ions into the surrounding atmosphere. As a result, the part that is being protected is enclosed in a VCI-rich atmosphere. The VCI vapor then interacts with the metal surface. VCI molecules attach themselves to the metal surface by creating powerful bonds with metal atoms. This creates a very thin invisible layer of passive oxide on the metal.
As a result, VCI corrosion protection can protect metal parts from rust and corrosion for many years. VCIs work for both ferrous and non-ferrous metals. These chemicals can be useful in situations where it is not practical to apply surface treatments to protect the metal from rust or corrosion.
Invisible Layer of Protection
When you use VCI packages for your metal parts, you will not notice the presence of any film since the layer is only a few molecules thick. The layer is dry and inert. It does not have any impact on the physical properties of the metal part. You can use the metal part right away by taking it out of the VCI package. You can paint, treat or use the metal part directly without the need to clean the surface.
VCIs have a major advantage over other rust prevention products. Due to their nature, VCIs can reach difficult areas that may not be accessible to conventional rust prevention products.
