Corrosion Prevention VCI film
Volatile Corrosion Inhibitor Film
VCI film is typically a plastic film (like polyethylene) that is impregnated with corrosion-inhibiting compounds. These compounds release vapor-phase inhibitors into the surrounding air, which settle on the surface of the metal and create a thin, molecular protective layer that prevents oxidation and rust. The VCI vapors are effective in both direct contact and in the air surrounding the packaged metal, providing full coverage protection
Vapor Release: When the VCI film is sealed around metal parts, the VCI molecules slowly evaporate and release anti-corrosive vapors into the enclosed space.
Protective Layer Formation: These vapor molecules then condense on the surface of the metal, creating an invisible protective layer
Inhibition of Corrosion: The protective layer prevents oxygen, moisture, and other corrosive agents from reacting with the metal surface, thus preventing rust or oxidation
Self-Replenishing: As long as the film remains sealed, the VCI continues to replenish the protective layer as needed, maintaining a continuous shield.
