Protection & Removal
Outstanding materials from Cortec that protect systems, parts and equipment from corrosion. Providing superior corrosion protection in adverse conditions and the ability of use on multiple metals.
VpCI or Vapour phase Corrosion Inhibitors are a revolutionary technology that simplifies corrosion protection and is ideal for keeping enclosed void spaces (e.g. packages, equipment internals, or structural metal cavities) rust-free.
VpCI can be supplied in many forms, from packaging materials to additives for water, oil and fuel systems.
Machined parts protection
Short to long-term protection of assets during lay-up/maintenance periods
Long-term storage without the need for controlled humidity environments
Reduced corrosion rates for equipment in use in high corrosion environments
Frequently Asked Questions
How does VpCI work?
VpCI works by sublimating, or vaporising, from the packaging material and saturating or filling the packaged atmosphere. Once the atmosphere is saturated, VpCI molecules bind, or adsorb, onto the metal surface. This action forms a thin, mono-molecular layer that prevents corrosion from occurring.
How is VpCI packaging different from desiccants?
Desiccants remove moisture from enclosed packaging. In some cases, this can reduce the risk of corrosion; however, once the desiccant becomes saturated, or a package is opened and more moisture enters the package, desiccant is no longer effective. VpCI provides active corrosion protection and is self-replenishing, providing corrosion protection even if the package is opened for a brief amount of time.
Do parts need cleaning after they are removed from the VpCI packaging?
Because VpCI chemistry first attempts to saturate the enclosed atmosphere of the packaging, once a metal part is removed from the packaging, VpCI molecules naturally leave the surface. This leaves a clean metal surface without need for cleaning.
What are some appropriate ways to seal VpCI packaging?
VpCI bags may be heat sealed, zip tied, zip closed or taped. VpCI papers may be wrapped around parts and taped to provide protection.
When should VpCI packaging be replaced?
VpCI packaging is typically specified to the needs of the application as a single use, industrially recyclable material. Packaging materials should be inspected and removed or replaced if they have holes, tears or punctures that cannot be easily repaired or patched with tape.
What is the shelf life of VpCI packaging products?
The shelf life on most Cortec packaging products is 2 years. That means if the products are stored in the original packaging and used within 2 years of the manufacturing date, Cortec is confident that the VpCI packaging product will function as if it were fresh off the production line.
Are the corrosion removers hazardous?
No, these materials are not classed as hazardous.
Will the corrosion remover protect the metal surface after the corrosion is removed?
There is a small amount of protection offered following the corrosion removal process to stop flash-rusting occurring. We recommend using additional corrosion protection following this process.
Are the corrosion removal products only applicable to iron/steel?
VpCI technology is effective on multiple metals. There are various corrosion removers available: from ferrous to aluminium and copper oxide.
Are the rust removal products environmentally friendly?
Yes, they are environmentally friendly solutions for corrosion control.
