Vapor phase corrosion inhibitors are chemicals that prevent water vapor from corroding metal components. VPCIs provide multi-metal protection with corrosion-inhibiting vapors that condense onto the surface of the metal and form a thin, uniform, molecular layer.
Paper and plastic bags used for shipping and storing metal components can be treated with these chemicals to prevent the corrosive effects of water vapor. While metal components are wrapped in paper or held in the bag, the VPCI chemicals will bond to the component surface in a thin, conformal molecular layer, thus preventing moisture.
VPCI is available as a paint-on primer or topcoat for metal that is continually exposed to an open environment, such as valves. The coverage is complete – all surfaces, including crevices, cavities and other inaccessible void areas receive total protection. The VCI barrier is self-replenishing, even for packaging that is repeatedly opened and typically protects for up to 24 months.

Vapor phase corrosion inhibitors are largely used in storing replacement parts for machines (e.g. aircraft engine components or machine dyes) as well as some tools. Because not all supplies will be used quickly or may be stored in humid locations, VPCIs provide a method of maintaining component integrity until the part is needed.
