VCI is the generic term for “volatile corrosion inhibitor,” “vapor corrosion inhibitor,” or “Vapor phase Corrosion Inhibitor,” a revolutionary technology that simplifies corrosion protection and is ideal for keeping enclosed void spaces (e.g., packages, equipment internals, or structural metal cavities) rust-free. We have trademarked our Cortec® brand of VCIs under the name VpCI® to help ensure our customers are getting the premium VCI products that are trusted globally.
