VpCI®-329 Superconcentrate


VpCI-329 Superconcentrate (SC) is a vapor corrosion inhibiting oil-based concentrate for lubricating and preservative oils. VpCI-329 SC 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, VpCI-329 SC releases vapor phase corrosion inhibitors into the air that attach electrochemically to the metal surface



• Saves shipping and inventory expenses
• Treated oils perform effectively even under the adverse conditions of 100% relative humidity and in the presence of such corrosive species as chlorides, sulfur compounds, or hydrogen sulfide
• Contains no hazardous chromates, nitrites, or phosphate inhibitors
• Easily diluted with lubricating and preservative oils
• Provides universal corrosion protection to ferrous and non-ferrous metals
• Non-toxic and thermally stable, providing longlasting corrosion and vapor phase corrosion protection
• Oils treated with VpCI-329 SC can conform to MIL-P-46002 and MIL-C-16173D (Grade 3
