Cortec’s Vapor phase Corrosion Inhibitor (VpCI®) technology represents a breakthrough solution in corrosion prevention. VpCI® products protect metals with a chemically adsorbed molecular layer that provides multimetal corrosion protection. The coverage is complete – all surfaces, crevices, cavities, and other inaccessible void areas receive total protection. The VpCI® barrier is self-replenishing, even for packaging that’s repeatedly opened, and typically protects for up to 24 months.
