Volatile Corrosion Inhibitors

Volatile corrosion inhibitors (VCIs) are chemical compounds that protect metal surfaces from corrosion. They are volatile substances that can vaporise or sublimate into the surrounding atmosphere. When used in an enclosed space, such as a package or a storage container, these compounds release vapours that create a protective layer on the metal surfaces.

The protective layer formed by VCIs adsorbs onto the metal surface and inhibits the electrochemical reactions that cause corrosion. This layer acts as a barrier, preventing moisture, oxygen, and other corrosive agents from reaching the metal and causing oxidation.

Volatile corrosion inhibitors can be used in various industries, including manufacturing, transportation, and storage, to protect metal parts, components, and equipment during storage and shipment. They are particularly useful for long-term storage or when metal surfaces are exposed to harsh environmental conditions.

We offer a wide range of VCIs for different types of metal packaging applications. Some are designed to release a protective vapour for a few weeks, while others can protect for several years. Proper packaging and application methods can maximise the benefits of VCIs and help prevent corrosion on metal surfaces.
