(= Volatile Corrosion Inhibitor, Vapour Phase Corrosion Inhibitor). Volatile anti-corrosion additives, which evaporate into the gas phase and inhibit corrosion processes on metallic surfaces in contact to the gas phase. VCI substances are in most cases part of the packaging material (paper, cardboard, nonwoven material, plastic sheets, foils, foamed plastic) or are added separately as powder, spray or oil. VCI materials are used for the transport of corrosion-sensitive parts and machinery. After removal of the packaging, VCI materials evaporate completely and do not leave residues on the protected parts enabling a further processing of the parts without cleaning.
