VCI

Get Ready to Ship Your Auto Parts The automotive industry is an American institution. Since the early days in Detroit, automotive manufacturing has been a proud symbol of the ingenuity, dedication, and hard work of the American people. This staple of our nation continues on today – from major vehicle manufacturers that have been around since day one to smaller parts and autobody shops that are found throughout the entire country. No matter the size of your business, the individual components are the fun …

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 surface area of the metal, protecting equipment from corrosion and rust during storage and transit. If you're in any of the following industries, please …

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 when an electrolyte (water, oxygen, etc.) is present on the surface of a metal. The corrosion process begins when electrons flow through the electrolyte …

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 both ferrous and non-ferrous metals. Non-Ferrous Metals – Indicates metals other than iron and alloys that do not contain an appreciable amount of iron (aluminum, copper, …

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 cell (the flow of electrons in the metal and the flow of ions in the electrolytic surface layer) is unable to establish itself. Corrosion is halted. …

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 in the presence of moisture and/or high humidity. Natural, neutral kraft paper or polyethylene film used as the carrier for the VCI. The overall packaging …
