Vci Film

Product Introduction:
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 metal
2.Transparent and beautiful, easy to observe the status of the packaged
3 . The protected me t a l needs no surface pretreament
4.Environmental protective, innocuous, completely recoverable
5.Convenient for use, simple procedures, economical and practical
6.Double functions of corrosion proof and damp proof.

Typical Physicochemical Characteristics:
Appearance: transparent film
Color: grass green, yellow, blue, etc.
Thickness: 0.03mm~0.25mm
Term of corrosion inhibition: more than 2 years.

Commended 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 packaging
2. 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 packaging
4.The product shall be treated with anti-corrosion process after the completion of production; and
the product temperature shall not higher than 50íµ before packaging
5.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 25cm
7.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.).
