VCI (Vapor Corrosion Inhibitor) powder works by releasing a volatile compound into the surrounding air. When applied to a metal surface or packed with metal items, the VCI molecules are released into the enclosed environment. These molecules then settle on the metal surfaces and form a protective layer. This layer prevents corrosion by either: Creating a Barrier: The VCI molecules form a thin, protective film on the metal surface that blocks moisture, oxygen, and pollutants from reaching the metal, which are the main contributors to rust and corrosion. Neutralizing Corrosive Agents: Some VCIs are chemically active and can neutralize acidic compounds or moisture that might otherwise lead to corrosion.
