VpCI® 322 is an oil based, concentrated corrosion protection solution. Cortec VpCI 322 performs well both indoor and outdoors.
Cortec VPCI technology is used in this formula. They form a thin, robust, mono layer film that attaches to metal surfaces providing outstanding contact corrosion and rust protection.
Vapour Phase Corrosion Inhibitors (VPCI) are used in the 322 formula. This provides protection in addition to the physical barrier of the film itself. The VPCI molecule essentially evaporate into the air above the corrosion inhibitor oil.
These VPCI molecules ‘cling’ to metal surfaces and can provide long term rust protection.
VPCI 322 Key Points
- Provides ‘multi-metal’ rust protection for both ferrous and non-ferrous metals.
- Barium, Chromates, Phosphate Inhibitor & Nitrate free.
- High flash point.
- High thermal stability formula. Long term contact corrosion with Vapour Phase technology.
- Will pass easily through a 5-micron filter.
- Suitable for use with hydraulics.
- Compatible with chlorides.
- VPCI 322 can be used at a 5-10% level of concentration ratio to hydraulic fluids, does not affect viscosity at lower temperatures or pour point.
- Can be used with the majority of synthetic and mineral based oils.
- Effective when used in both operating & intermittent conditions.
Typical Applications
Various hydraulic oil grades and viscosities are compatible with 322 for intermittent operational requirements. It can be added to oil in a 9 to 1 ratio, 1 x part Cortec VPCI 322 with 9 parts chosen oil.
This provides corrosion protection for up to 2 years.
Fogging cavities or inner spaces with 322 is also possible for equipment in awkward or difficult to reach places. Here consider using the 322 concentrate (1 ltr) per 35 ft³ (1.1m³) of enclosed space.
Use this method for equipment such as tanks, gearboxes, and other differentials. Either during transportation or storage.
Can be removed using an alkaline based solution such as the VPCI 414 cleaner degreaser.
Commonly used as a corrosion inhibitor in the oil and gas industry.

Frequently Asked Questions
• What exactly is Cortec VpCI-322 and how does it protect metals?
Cortec VpCI-322 is a highly effective, oil-based concentrate specifically formulated to provide dual-phase corrosion protection. It works by forming a tenacious film on metal surfaces, offering excellent contact corrosion protection, while simultaneously releasing Vapor phase Corrosion Inhibitors (VpCIs) that travel through the air to protect inaccessible areas above the oil line.
• What's the unique dual-phase protection of Cortec VpCI-322?
The real cleverness of Cortec VpCI-322 lies in its dual-phase action. Firstly, it contains oil-soluble inhibitors that create a strong, clinging film directly on metal surfaces that are in contact with the oil. Secondly, its unique VpCI technology allows for the release of protective vapors into the air space, which then condense on all metal surfaces, even those not directly coated by the oil, providing comprehensive protection.
• Which types of metals can Cortec VpCI-322 effectively protect?
Cortec VpCI-322 is designed to offer broad-spectrum protection for a wide range of metals. This includes common ferrous metals like carbon steel and stainless steel, as well as various non-ferrous metals such as copper, brass, aluminum, galvanized steel, cadmium, magnesium, silver, and zinc.
• How long can I expect Cortec VpCI-322 to protect equipment during storage or operation?
When properly applied at the recommended dilution, Cortec VpCI-322 can provide significant corrosion protection for up to 24 months, making it an ideal solution for long-term storage or intermittent operation of machinery.
• Is Cortec VpCI-322 suitable for both indoor and outdoor exposure?
Yes, Cortec VpCI-322 is engineered to deliver excellent corrosion protection in a variety of conditions, including both indoor storage environments and situations where equipment might be exposed to open air.
