How to use Volatile Corrosion Inhibitor Bags
1. When using VCI Bags firstly ensure that the products in question are clean and dry as well as being free from duct and debris which may prevent the chemical solution from attaching.
2. Wear gloves!!! Be aware that any fingerprints on the product itself may also stop the formula applying in that area.
3. As a general rule an area of 30cm should be kept between the metallic surface and the VCI packaging itself. Larger VCI export packaging designs are available for larger items where rust prevention using this method may be difficult.
4. Based on normal ambient conditions i.e. room temperature the protective layer should form within 24 hours once the goods are in sealed packaging. Other delivery methods may take longer.
5. When judging how long VCI last’s it essential to take into consideration any other packaging materials that are being used in conjunction. Is there another Packaging layer? Is Desiccant being used? What will the temperature be in the warehouse or storage facility? What sort of handling will it receive in by the freight forwarder or Haulage Company?
6. It’s worth mentioning that VCI products can be opened briefly in order to check the contents as the protective barrier layer will regenerate somewhat.
7. VCI protection products are ready to go out of the box. Make sure they are well sealed and are stored in a cool, dry place with not exposure to direct sunlight.
8. In order to prevent an unwanted chemical reaction do not use in conjunction with another VCI compound.
