Cortec CorShield VpCI® 368® is a high performance fast action, solvent based temporary coating that provides outstanding multi metal protection in the harshest of outdoor environments.

Conforms in full to requirements of MIL PRF 16173 Grade 1 & Grade 2. Available in convenient, easy to use aerosol cans and 5 Gallon (19ltr) & 55 Gallon (208ltr) drum pails for larger, spray/brush on projects.

Designed for unsheltered, exposed environmental conditions Cortec VpCI 368 provides unbeatable multi metal protection. CorShield VpCI 368 can easily be removed with cleaners such as VpCI 414 alkaline cleaner degreaser.

VpCI 368 conforms in full to the commercial equivalents of both MIL PRF 16173 Grade 1 & MIL PRF 16173 Grade 2.

Cortec VPCI 368 produces a ‘wax-like’ consistency and offers multi metal corrosion inhibitor protection, for both ferrous and non-ferrous metals. In addition it is possible to match some custom colours if a ‘same colour as the surface’ solution is required.

NATO 6850-66-132-5848, 6099 & NSN 8030-00-062-6950.

Application Guidance for Cortec Corrosion Inhibitor VPCI 368

Surface Preparation – ensure substrate is grease, oil, dirt and fingerprint free. Also ensure the surface is free from rust inhibitors except Cortec Corporations own compatible product.

As a minimum Valdamark recommends SSPC-SP1 when using over painted surfaces. Where bare metals are concerned, we recommend a NACE ~3/ SSPC-SP6. Consult with technical services or test the systems adhesion prior to a full application works.
VPCI 368 must be agitated and mixed prior to use to obtain a uniform consistency. We recommend using a ‘squirrel cage’ type mixer or a handheld tool, equivalent also. You can also apply the solvent based coating using a spray, brush, roller or dip method.

Typical Equipment Calibrations

Using a conventional spray / HVLP:

• Tip 0.02”-0.11” (0.5-2.8mm) – varies depending on pressures & viscosity readings.
• Air pressure set to between 45 & 55 psi.
• Fluid pressure set to 10 psi.
• Fluid hose should be ⅜” (0.95cm internal dimension) keeping a maximum length of 50 ft (15.2mtr). A ¼” (0.64cm internal dimension) hose can be used but will likely need to be adjusted for proper functioning. Ensure spray gun pot is dual regulated & is kept at the same elevation as the spray gun housing itself.

For Assisted Airless (& Airless) Applications:

• Tip 0.015”-0.035” (0.38-0.89mm) – varies depending on pressure and viscosity readings.
• Pressure set between 1800 & 2500 psi.
• Ensure the hose is ⅜” (0.95cm internal dimension) as a minimum requirement but also a ¼” (0.64cm internal dimension) airless spray gun extension wand may be also be used for convenience. Here a maximum length of 100 ft (30.5 mtr) is suggested.

Post Application & Clean up

You should clean any tools and equipment immediately after use with butyl acetate when the coat is still well. When dry use butyl cellusolve or alternatively MEK for further treatment.
