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.

FEATURES
•Contains no hazardous chromates, nitrites, or phosphate inhibitors
•High flash and fire points
•Protects ferrous metals, zinc, galvanized steel, aluminum, copper, and brass.
•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 is commercial equivalent to MIL-PRF-46002C (Grade 1)

METHOD OF APPLICATION
Short-term protection: One part VpCI®-329 to 19 parts oil. Medium-term protection: One part VpCI®-329 to 9 parts oil. Long-term protection: One part VpCI®-329 to 4 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.
