How Cortec VpCI (Vapour Phase Corrossion Inhibitors)​​ Works?

  • Vaporizes
  • Conditions enclosed atmosphere with a protective vapor.
  • Vapor condenses on all metal surfaces.
  • Ions dissolve in moisture layer (water electrolyte).
  • Protective ions are attracted to metal surfaces.
  • Ions form a thin molecular protective layer at the metal surface.
  • Protective layer re-heals and self-replenishes through further condensation of the vapor.
  • VpCI® combines with other functional properties. Antistatic, Lubricating, Cleaning, Paint Removing, Desiccant, Polymeric, Coatings, Rust Removing, Fire Retarding.

How Cortec VpCI Cut Costs?

Cortec® technology can be used in each stage of the product’s lifecycle, beginning with the production of metal stock to the actual application. When properly applied, Cortec’s VpCI®/MCI® technology substantially cuts time and cost throughout the entire product life cycle: Manufacturing, Storage, Shipping, and Field service.

Traditional Coatings VS Cortec® Coatings

All Cortec® coatings deliver exceptional protection, even in extreme outdoor industrial, marine, or tropical environments.

Cortec® can recreate your current colors with a customized formula or simply match it from our extensive list of standard colors. Most Cortec® coatings have outstanding UV resistance. Cortec® products also have excellent gloss retention, which is important when aesthetics are a consideration.

With environmentally safe VpCI® technology, your equipment and products will be effectively protected against humidity, saltwater, and oxidizing atmospheres as well as corrosive industrial, marine, and tropical environments.


Traditional coatings rely on sacrificial metals (zinc, chromates, aluminum) for inhibition. Due to the large particle size of these inhibitors, gaps exist which allow corrosion to start and eventually expand, causing coating failure.


Cortec® VpCI® coatings use the patented VpCI® technology to protect the metal substrate with a tight bonding molecular structure. This system eliminates the gaps which occur with traditional inhibitors and prevent corrosion from starting.

Why Use Cortec VpCI Coatings and Choose Us?

Health, safety, and pollution control

Cortec’s formulations, using the newest chemical technology available, help alleviate your concerns in the areas of health, safety, flammability, and pollution control.

Multimetal protection

A full range of corrosion inhibitors are available to protect ferrous and non-ferrous metals, including formulations that protect combinations of metals.

Short-term and long-term protection

There’s a Cortec® solution for temporary protection during in-plant processing, medium-term protection for shipment and storage, or extended protection for lay-up, mothballing, and field service.

Application for a variety of environmental conditions

Protect your metals and products against corrosion from all aggressive atmospheres.

Protected parts are immediately ready for use

The protective invisible layer deposited by Cortec® Vapor phase Corrosion Inhibitors (VpCI®) needs no removal. No degreasing, scraping, cleaning, or further preparation is necessary before processing, installation, or use. Your VpCI® protected components, parts, and finished assemblies are ready for immediate use. Cortec’s barrier coatings are easily removed with conventional cleaning methods.

Does not alter most material properties

In the majority of cases, the invisible protective ionic layer of Cortec’s VpCIs does not alter important surface properties. This is true even for the most precision electronic devices where conductivity, per-mittivity, and dimensional tolerances are crucial.

For tiny electronic devices to tanker holds

Cortec’s VpCI® technology protects any size products — from printed circuit board components during process, stored parts to large containerized shipments.

VpCIs are compatible with many synergistic fluids, coatings, and technologies

VpCI® technology can be integrated into nearly every process.
