Oil layer rust preventatives are still very popular to prevent corrosion, but it is still rare to find VCI Rust preventive additives in most formulations. The main reason for their popularity is that they are usually affordable, easy to apply, they tend to require less surface preparation (in many cases they clean and protect at the same time), are finger print corrosion resistant and they've been along for a very long time. The ongoing trend is to try and replace classic mineral/solvent based formulations for renewable oil based formulations (canola oil and soybean oil mainly). Within the RP Oil range we have available, not only products that work through moisture or water displacement, but also some formulations that work by forming an emulsion or sometimes a gel with moisture. These type of products are more effective in the long term specially to avoid corrosion in porous metals such as cast iron. The most common type of criteria to determine the most suitable RP Oil are: protection time, type of metals that need protection, particle size (avoiding filter clogging), how much vapor phase protection is required, environmetal concerns, suitability of the product to provide protection in working or idle machinery, food grade requirements and others. No matter the application, we will always have the most cost effective product that covers all the requirements set forth by our customers.

VCI Oil Based Concentrate
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 D is a ready-to-use oil-based rust preventive. VpCI®-
329 D provides excellent protection to metals in indoor and
outdoor sheltered conditions. VpCI®-329 D 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 D
releases vapor phase corrosion inhibitors into the air that attach
electrochemically to the metal surface.
VpCI®-329 D is great for protecting metal parts that require a light
coat of oil rust preventive for further processing and shipment..
