How VpCI Film Can Protect Oversized Metal Items from Corrosion

Corrosion is a major problem for metal items, especially those that are oversized and exposed to harsh environments. Corrosion can damage the appearance, functionality, and safety of metal items, and cause significant economic losses. Therefore, finding effective ways to prevent corrosion is crucial for many industries and applications.

One of the most innovative and convenient solutions for corrosion prevention is VpCI (Vapor phase Corrosion Inhibitor) film, developed by Cortec Corporation. VpCI film is a plastic film that contains corrosion inhibitors that can protect metal items from rusting, both by forming a physical barrier and by releasing vapors that create a protective layer on the metal surface. VpCI film can be used to wrap, cover, or seal metal items of various shapes and sizes, and provide long-term corrosion protection.

Benefits of VpCI Film

VpCI film has many advantages over conventional methods of corrosion prevention, such as coatings, oils, or desiccants. Some of the benefits of VpCI film are:

  • It is easy to apply and remove, without requiring special equipment or labor.
  • It does not leave any residue or contamination on the metal surface, and does not affect the performance or appearance of the metal item.
  • It is environmentally friendly and biodegradable, and does not contain any toxic or hazardous substances.
  • It is versatile and adaptable, and can be customized to fit different metal items and applications.
  • It is cost-effective and durable, and can provide corrosion protection for up to two years.

Applications of VpCI Film

VpCI film can be used to protect a wide range of metal items, from small components to large structures, and from indoor storage to outdoor exposure. Some of the applications of VpCI film are:

  • Packaging and shipping of metal parts, equipment, and machinery.
  • Storage and preservation of metal items, such as tools, spare parts, and historical artifacts.
  • Construction and maintenance of metal structures, such as bridges, buildings, and pipelines.
  • Protection of metal items during harsh conditions, such as high humidity, salt spray, or extreme temperatures.

One of the unique features of VpCI film is that it can be used to protect extremely oversized metal items, such as those taller than a person’s head or too wide to wrap around. VpCI film comes in widths up to 30 feet, allowing users to package extra-large objects. When this is not wide enough, users can seam together sections of heavy-duty VpCI-126 HP UV shrink film and MilCorr VpCI shrink film to shrink wrap extremely large or bulky items that will be exposed to outdoor conditions. Past applications of VpCI film on large, unwieldy metal goods include a metal ring 3.5 by 6 yards in diameter, wind energy turbine components, giant power cable drums, and 3D printers.

Comparison of VpCI Film with Other Methods

To illustrate the effectiveness and convenience of VpCI film, we can compare it with other methods of corrosion prevention for oversized metal items. The table below shows some of the criteria and ratings for different methods, based on a scale of 1 to 5, where 5 is the best and 1 is the worst.

Method Ease of Application Ease of Removal Residue or Contamination Environmental Impact Cost Durability
VpCI Film 5 5 5 5 4 4
Coatings 2 2 3 2 3 3
Oils 3 3 2 3 3 2
Desiccants 4 4 4 4 2 1

As we can see, VpCI film has the highest ratings for most of the criteria, and is the most suitable method for protecting oversized metal items from corrosion.
