Q: What is VpCI® Technology

A: VpCI® is the generic term for “volatile corrosion inhibitor,” “vapor corrosion inhibitor,” or “Vapor phase Corrosion Inhibitor,” a revolutionary technology that simplifies corrosion protection and is ideal for keeping enclosed void spaces (e.g., packages, equipment internals, or structural metal cavities) rust-free. 

Q: What is VpCI® And How Does It Work?

A: VpCI®, or Vapor-phase Corrosion inhibitor, is a technology designed to protect metals from corrosion. Unlike our traditional corrosion inhibitors that are applied directly to the surface, VpCI® works by releasing a vapor that forms a protective layer on the surface of the metal. This invisible shield actively repels moisture, oxygen, and other corrosive elements, keeping the metal safe from rust and degradation. For example, suppose you have a piece of equipment stored is a warehouse. Over time, humidity and temperature fluctuations can obviously cause condensation, leading to corrosion of your equipment, right? By using VpCI® corrosion protection, you can make sure that your equipment remains in pristine condition. The vapor molecules reach every nook and cranny, even in complex machinery, providing comprehensive protection. 

Q: Advantages of VCI/VpCI Technology

A: VCI technology has many advantages. As suggested, it typically does not require the special removal of a coating or greasy rust preventative. This reduces labor time and hazardous waste disposal fees from having to clean off traditional petroleum-based rust preventatives—often with solvent-based cleaners. It also solves the problem of protecting intricate equipment internals (e.g., pipes, boilers, valves) where it would be difficult if not impossible to apply a coating or liquid rust preventative. VCIs do not require a constant source of electricity as needed for dehumidification systems. VCI technologies protect multiple metal types and work in multiple phases—liquid, vapor, and interface—so they can be used to inhibit corrosion on metal surfaces below and above the fluid level in water treatment or oil and gas applications. The characteristics of VCI packaging material work together to save time and money and offer more thorough, reliable, and easier-to-use protection than a variety of other metals preservation strategies. 

Q: Safety Benefits of Cortec’s VCI/VpCI Technology

A: Cortec® VCIs under the VpCI® brand name are generally safer to handle and less hazardous than other VCIs such as DICHAN (one of the first, highly toxic VCIs on the market) or those that rely heavily on nitrites. Many Cortec® products containing Vapor phase Corrosion Inhibitors are also recyclable or water-based and typically have a lower environmental impact than many harsher chemicals.
