Cortec VpCI 329 Corrosion Inhibitor Oil-based Concentrate

Features

VpCI-329 is a vapor corrosion inhibiting oil-based concentrate for use with lubricating, hydraulic, and preservation oils. VpCI-329 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.

 

• Contains no hazardous chromates, nitrites, or phosphate inhibitors
• High flash and fire points
• Protects ferrous metals, zinc, galvanized steel, aluminum, copper, brass, cadmium, and silver
• Zinc-free
• Compatible with most oils
• Can be fogged into metal compartments
• Parts can be dipped and stored
• VpCI-329 provides good salt spray resistance
• NATO #6850-66-132-6100 NSN #6850-01-470-3359
• VpCI-329 conforms to MIL-PRF-46002C(Grade1)

Applications

Short-term protection: One part VpCI-329 to 20 parts oil.

Medium-term protection: One part VpCI-329 to 10 parts oil.

Long-term protection: One part VpCI-329 to 5 parts oil.

Storing metal parts: Spray, dip or brush VpCI-329 onto metal parts before storage.

Storage for lubricating, hydraulic and metal cutting systems:

Add Cortec® VpCI-329 to oil in engines before storage. For best results, add VpCI-329 to the oil, then
cycle or run the engine for 10 minutes before shutdown. After storage, the engine can be normally
operated. There is no need to remove VpCI-329 from an operating engine.
