Unobtrusive Removable Coating for Corrosion Protection Using VpCI®-391

Removable coating for corrosion protection using the VpCI 391 formula is highly beneficial in an array of applications where performance matters.

Corrosion Protection
Corrosion is one of the greatest menaces in most packaging industries and its effects are devastating. It weakens parts, which undoubtedly poses a great danger to personnel and it is cost-intensive. Additionally, corrosion lowers the quality of parts.

It would be logical to think that using VCI packaging bags and films should solve the problem by protecting parts from corrosion. However, they are not always the optimal solution. There are some metal parts with unique shapes that require unique storage (or transportation) conditions.

That’s where the VpCI®-391 formula shines. It is an inconspicuous removable coating for metal parts with unique shapes and storage or transit requirements. The coating is ideal for both the long-term and temporary corrosion protection of these metal parts.

Why You Should Consider Using VpCI®-391 Removable Coating for Corrosion Protection
VpCI®-391 removable coating offers an alternative to using traditional methods of corrosion protection. Traditionally, people would apply a protective layer of oil or grease on the surfaces of metal parts as a corrosion protection method.

However, Cortec’s VpCI®-391 does away with all that.

The VpCI®-391 removable coating is a non-sticky, water-based film that is applied to the surfaces of metal parts. Upon drying, it forms a thin coating over your metal parts which acts as a corrosion inhibitor. In addition, VpCI®-391 also helps prevent scratches on parts as well as other minor physical abuses.

The best part about using Cortec’s VpCI®-391 is that it is inconspicuous – one can hardly notice if parts are covered using this film. It is suitable for both indoor and outdoor use and it is easily removable using an alkaline cleaner degreaser if desired.

Where to Use VpCI®-391 Removable Coating
First, it is important to note that VpCI®-391 contains vapor phase corrosion inhibitor technology. It is the primary component that protects parts from corrosion. VpCI works by diffusing a molecular layer of protection on the surfaces of metal parts.

There are countless possibilities for using the VpCI®-391. Some of the most popular industries that use it are in heavy machinery, automobile, structural steel, in setting up pipelines, machinery, among others.

When to Use VpCI®-391 Corrosion Protection Removable Coating

  • When storing sensitive metal parts – the VpCI®-391 is an ideal corrosion protection coating that is widely used to protect parts in storage from corrosion. The coating prevents metal parts from rusting.
  • You can also use the ​​VpCI®-391 to protect your sensitive metal parts from corrosion during transit. You can spray the VpCI®-391 to protect these metal parts from harsh weather that could cause corrosion.

Many logistics companies have sprayed this corrosion protection coating over metal parts such as rims, unpainted metal tubes, etc. Doing so helps these parts retain their new look by protecting them from minor physical abuses.

  • Preventative maintenance – some industries use the VpCI®-391 corrosion protection coating as a preventative maintenance for their equipment. Put simply, spraying this corrosion protection layer could make new equipment last longer and maintain its new look.


Most front-loading or even fertilizer companies spray the VpCI®-391 annually on their trucks and heavy machines. It helps prevent corrosion and makes their locomotives retain their new look.

In a Nutshell
VpCI®-391 removable coating is an ideal solution for both long-term and temporary corrosion protection. It is good for both indoors and outdoors and offers corrosion protection for parts in storage, transit or for preventative maintenance. In other words, it is effective, easy to apply and unobtrusive – a person can hardly tell if parts have been covered by VpCI®-391.
