Cortec VpCI 322 Oil Concentrate


VpCI-322 oil-based concentrate adds corrosion protection to lubricating or hydraulic oils. VpCI- 322 provides excellent protection in indoor or open air conditions. First, oil-soluble corrosion inhibitors offer a tenacious film which clings to metal surfaces, giving excellent contact corrosion protection. In addition to this film barrier, VpCI-322 releases vapor phase corrosion inhibitors into the air above the oil. These VpCIs attach to metal surfaces for additional corrosion protection.


• Corrosion protection to ferrous and non-ferrous metals
• Does not contain hazardous barium, chromates, nitrites, or phosphate inhibitors
• High flash point
• Low in toxicity and thermally stable, providing long-lasting contact and vapor phase corrosion inhibitors
• Passes through a size 5 micron filter
• Can be used in hydraulic applications
• Provides protection in presence of chlorides
• When added at a concentration level of 5-10% to hydraulic fluids, does not affect pour point and viscosity at low temperatures
• Compatible with most mineral and synthetic oils
• Suitable for both operating and intermittent use conditions



Lubricating and hydraulic oil systems for intermittent operation:
Add VpCI-322 to oil at a ratio of 1 part VpCI-322 to 9 parts oil for 24 months protection.

Tanks, gearboxes, differentials – stored or shipped dry:
Fog cavity interior with VpCI-322 concentrate using 1 quart (1 liter) per 35 ft3 (1.1 m3) of enclosed space.
