Wet-film Corrosion Inhibitor


VpCI®-369 is an oil-based temporary coating that provides extreme corrosion protection in aggressive environments and is one of Cortec’s most-popular wet film corrosion inhibitors. It is an excellent option for protecting auto service parts and heavy equipment components before assembly.

Since VpCI®-369 is thixotropic, it can be mixed so that the product changes consistency to enhance sprayability for application with an airless sprayer. Once applied, it thickens so that it does not run off the metal. VpCI®-369 can be tinted to blue, green, or other custom colors if desired to help workers detect sufficient product coverage. Those working with military agencies can use VpCI®-369M as a MIL-spec version that conforms to MIL-PRF-16173E (Grade 2).

VpCI®-369 is a great option for protecting bare, unpainted metal equipment parts that suppliers need to ship to the assembly plant. As a long-term rust preventative, it is also excellent for service parts or spares that will be laid aside for five or 10 years before they might be needed again (e.g., marine engine crankshafts).

Because VpCI®-369 does not dry, it can be used as a dual lubricant and rust preventative for moving parts. It is much easier to remove than other coatings that dry to a waxlike texture. Hence, there are countless industrial components that can benefit from a light coating of VpCI®-369 for either short- or long-term rust prevention:

  • Crankshafts
  • Camshafts
  • Engine heads
  • Engine assemblies
  • Wheel assemblies
  • Axles
