What Is VCI Packaging and Why Is It Important?
MetPro VCI Paper prevents corrosion from rust
If you're in this industry, chances are you've heard about VCI packaging and how it directly impact your business. This packaging contains special chemicals that are scientifically designed to release rust-inhibiting molecules. These molecules attach to the...
What is VCI?
VCI is a vapor corrosion inhibitor; this is a class of chemical compounds that emit a rust-inhibiting vapor into the air to stop corrosion on metal surfaces. Typically a packaging material (like paper or poly film) is the carrier for the VCI chemicals, but they can also be delivered through plastic, paper, or foam emitters.
Corrosion happens...
Chemical Scavenging Technology – patented chemical formulations that neutralize any acid gases and prevent them from coming in contact with metal components sealed inside the package.
Ferrous Metals – metals made from iron (steel, carbon steel, cast iron, etc.)
Multimetal Corrosion Inhibitors – chemicals that inhibits corrosion on...
Corrosion inhibitor compounds vaporize from the paper or film. They are attracted to the charged surface of the metal by virtue of their polar orientation.
The VCI molecules align on the surface of the metal to a depth of 3 to 5 molecules. This layer of molecules passivates the charged surface and creates a barrier that prevents oxidation. The corrosion...
VCI Protection is a Function of:
Which Metals are in need of protection.
Corrosion inhibiting chemicals used and their effectiveness on the metals.
Ratio of chemicals in the formulation.
Amount of volatiler corrosion inhibitors on the paper or in the film.
pH of the finished product.
Water solubility and the effectiveness of the corrosion inhibitor...
