VpCI®-329 is a vapor corrosion inhibiting concentrate for use with lubricating, hydraulic and preservation oils. Provides excellent protection in sheltered outdoor/indoor conditions. VpCI®-329 protects in two unique ways by offering a tenacious film, which clings to metal surfaces, as well as vapor phase inhibitors into the air above the oil. The vapors condense and form a protective barrier on metal surfaces that are not in contact with the oil. This combination allows complete protection to internal system parts. Conforms to MIL-P-46002B, MIL-I-85062, MIL-C-16173D (Grade 3). VpCI®-329 F is FDA approved.


VpCI-329 F is a USDA (US Department of Agriculture) accepted oil-based concentrate for use as an additive to lubricating and hydraulic oils or as a ready-to-use corrosion preventive fluid. VpCI-329 F protects in two unique ways. First, oil-soluble corrosion inhibitors offer a tenacious film which clings to metal surfaces, providing excellent contact
corrosion protection. In addition to this film barrier, Cortec VpCIs release vapor phase corrosion inhibitors into the air that attach electrochemically to the metal surface.



• Performs effectively even under the adverse conditions of 100% relative humidity and in the presence of such corrosive species as chlorides
• High flash and fire points
• Contains no hazardous chromates, nitrites, or phosphate inhibitors
• VpCI-329 F is easily diluted with lubricating, hydraulic, and preservative oils approved for food plants
• Provides universal protection to ferrous and nonferrous metals
• Non-toxic and thermally stable, providing long-lasting contact and vapor phase corrosion protection
• VpCI-329 F is a special version of VpCI-329, which has been accepted by the USDA “for use on packaging materials in indirect contact with meat or poultry”

Conforms to FDA regulation, CFR 178.3300 Corrosion inhibitors used for steel or tinplate; for indirect food contact.



Dilute VpCI-329 F with lubricating, hydraulic, or preservative oil. Can also be sprayed, dipped, or brushed onto surfaces.

Short-term protection (up to 6 months): 1 part VpCI-329 F to 20 parts oil.

Medium-term protection (up to 12 months): 1 part VpCI-329 F to 10 part oil.
