How Do VCI Storage Bags Work - Arms Preservation Inc

VCI Firearm Storage Bags

VCI (Volatile Corrosion Inhibitor) storage bags are designed to protect metal from rust through a controlled release of VCI molecules within the enclosed airspace of the bag. Here’s how they work:

  1. VCI Technology: The storage bags are made from materials that incorporate VCI molecules. These molecules are typically embedded in the plastic or paper material of the bag itself.

  2. Vapor Phase Action: Once the metal object is placed inside the VCI storage bag and the bag is sealed, the VCI molecules start to vaporize due to their volatile nature.

  3. Formation of Protective Layer: The VCI molecules disperse within the airspace inside the bag and adsorb onto the metal surface. They form a very thin, invisible protective layer on the metal.

  4. Corrosion Inhibition: The VCI molecules interfere with the electrochemical reactions that lead to corrosion. They can either block the anodic sites (where metal ions are released) or the cathodic sites (where reduction of oxygen occurs), thus slowing down or preventing the corrosion process altogether.

  5. Long-Term Protection: The VCI molecules continue to release from the bag material over time, ensuring that the protective layer remains effective as long as the bag is sealed and intact.

  6. Application: VCI storage bags are used in various industries where metal components or parts need to be stored or transported without risk of corrosion. They are particularly useful for long-term storage or during shipping where metal items might be exposed to humid or corrosive environments.

  7. Environmental Benefits: Like other VCI products, VCI storage bags are typically non-toxic and environmentally friendly, making them a preferred choice over traditional corrosion protection methods that may involve oils or coatings.

In essence, VCI storage bags protect metal from rust by creating a controlled environment where VCI molecules form a protective barrier against corrosion, effectively preserving the metal’s integrity and reducing maintenance costs associated with corrosion damage.
