Cortec 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.

Method of Application
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.
