Volatile Corrosion Inhibiting (VCI) Film is the core technical product of Suzhou Keysun Company, and has passed the testing of Chinese Academy of Sciences, Wuhan Research Institute of Materials Protection and SGS, etc. It is a kind of corrosion inhibiting film produced in the co-extrusion method. When Keysun VCI film or VCI bag is used in the metal product packaging, volatile corrosion inhibitor gasifies in the constrained space and agglomerates on the metal surface, including holes, hollows, gaps and other inaccessible surfaces, forms a gas-phase protective layer, so as to prevent the metal products from corrosion. It is in compliance with the National Standard of the People's Republic of China, American Mi litary Standard MILB22019C and MILB22020C.Product Advantages:1.Be applicable to the corrosion inhibition of black and nonferrous metal2.Transparent and beautiful, easy to observe the status of the packaged3 . The protected me t a l needs no surface pretreament 4.Environmental protective, innocuous, completely recoverable5.Convenient for use, simple procedures, economical and practical6.Double functions of corrosion proof and damp proofTypical Physicochemical Characteristics:Appearance: transparent filmColor: grass green, yellow, blue, etc.Thickness: 0.03mm~0.25mmTerm of corrosion inhibition: more than 2 yearsCommended Purpose:The corrosion inhibition of aviation fittings, engines, auto fittings, components and mechanical equipments in storage and transport;Application Method and Attentions:1.Make sure the packaged content free from corrosion when packaging2. Keep the packaged content clean and free from any foreign matter or finger mark before packaging 3.Keep a dry environment and the operators shall wear gloves at packaging4.The product shall be treated with anti-corrosion process after the completion of production; and the product temperature shall not higher than 50℃ before packaging5.For VCI packaging, the most important proceeding is closed packaging; the tightness shall not less than 95%6.The space between VCI packaging film and packaged content shall not exceed 25cm7.The corrosion inhibiting package shall be applied. If the size or interior and exterior superficial area of content is too large or the environment is too wet during packaging, the assistant corrosion inhibiting additives, such as VCI powder, corrosion inhibiting drier, etc., shall be used inside the package. (Generally 1m space requires about 100g VCI powder.)
