Volatile Corrosion Inhibitor
What is a VCI?
A volatile corrosion inhibitor (VCI) is a substance that slowly releases a corrosion-preventative compound into a sealed air space, effectively protecting exposed metal surfaces. 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.
How does a VCI work?
- The VCI is incorporated into a packaging material, such as paper, film, or cardboard.
- When the packaging is sealed, the VCI molecules begin to vaporize.
- The VCI molecules diffuse throughout the air space in the package.
- The VCI molecules come into contact with the metal surfaces in the package.
- The VCI molecules form a thin, invisible layer on the metal surfaces.
- The layer of VCI molecules prevents moisture, oxygen, and other corrosive elements from coming into contact with the metal surfaces.
- The metal surfaces are protected from corrosion.
VCIs are a safe and effective way to protect metal surfaces from corrosion. They are non-toxic and non-flammable. VCIs are also environmentally friendly, as they do not release any harmful chemicals into the environment. They are free from nitrates, silicones, and phosphates.
Why use VCI over Oil?
Feature | Oil | Volatile Corrosion Inhibitor (VCI) |
Environmental Impact | Can be harmful to the environment | Non-toxic & environmentally friendly |
Safety | Can be flammable & Hazardous | Non-toxic and safe to use |
Effectiveness | Provides long-term protection but can run off. | Provides long-term protection without running off |
