Detailed Description
Volati le 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 fi lm produced in the co-
extrusion method. When Keysun VCI fi lm or VCI bag is used in the metal product packaging, volati le
corrosion inhibitor gasifies in the constrained space and agglomerates on the metal surface,
including holes, hol lows, gaps and other inaccessible surfaces, forms a gas-phase protective layer,
so as to prevent the metal products from corrosion. It is in compl iance with the National Standard of
the People's Republ ic of China, American Mi l itary Standard MILB22019C and MILB22020C.
Product Advantages:
1.Be appl icable to the corrosion inhibition of black and nonferrous metal
2.Transparent and beautiful, easy to observe the status of the packaged
3 . T h e p r o t e c t e d me t a l n e e d s n o s u r f a c e p r e t r e a tme n t
4.Envi ronmental protect ive, 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 fi lm
Color: grass green, yel low, 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 shal l wear gloves at packaging
4.The product shal l be treated with anti-corrosion process after the completion of production; and
the product temperature shal l not higher than 50℃ before packaging
5.For VCI packaging, the most important proceeding is closed packaging; the tightness shal l not
less than 95%
6.The space between VCI packaging fi lm and packaged content shal l not exceed 25cm
7.The corrosion inhibiting package shal l be appl ied. 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., shal l be used inside the
package. (General ly 1m space requires about 100g VCI powder.)
