Volatile Corrosion Inhibitors (VCIs) have been around since the 1940’s, when a product named Dichan was introduced into market. Dichan consisted of dicyclohexylamine-nitrite, which was described as a vapor phase corrosion inhibitor that had sufficient vapor pressure to release corrosion inhibiting molecules into the surrounding area. Eventually, this chemistry began to be coated onto paper,

When it comes to corrosion prevention during shipping and storage, two common methods are often discussed: Vapor Corrosion Inhibitors (VCIs) and desiccants. Although both aim to protect metal surfaces, their mechanisms and ideal applications differ significantly. Understanding these differences can help you choose the most effective solution based on your specific needs, environment, and duration
