During manufacture, storage and transport, corrosive substances in the environment easily attack metal items. These attacks can be prevented in two ways: the environment can be controlled or suitable packaging materials containing corrosion inhibitors can be used. Corrosion inhibitors when added to corrosive environments will drastically reduce corrosion rates. Vapor phase corrosion inhibitors or volatile corrosion inhibitors (VCIs) also called vapor phase corrosion inhibitors (VPIs), are similar to the organic adsorption type inhibitors, but they possess a high vapor pressure. VCIs are transferred to the surface of the metal to be protected by a sublimation and condensation process.
