VCI (Volatile Corrosion Inhibitor) oil is a type of oil that is specifically formulated to protect metal surfaces from corrosion during storage or transportation. It is a rust preventive oil that contains VCI technology, which is designed to provide a protective layer on the surface of the metal. VCI oil works by releasing volatile corrosion inhibitors into the air, which then condense and form a protective layer on the surface of the metal. This layer helps to prevent moisture and other corrosive agents from coming into contact with the metal surface and causing rust or corrosion. VCI oil is an effective and convenient way to provide long-term corrosion protection for metal components and products during storage or transportation. It is an important part of the rust prevention process for metal items and can help to extend their useful life and protect them from damage caused by corrosion.
