VpCI®-347 is a multifunctional corrosion inhibitor/heavyduty lubricant concentrate for metalworking operations. High performance characteristics make VpCI®-347 ideally suited for heavy-duty cutting, milling, turning, drilling, boring, broaching, gear cutting, and other machining operations. VpCI®-347 contains lubricating and corrosion inhibiting compounds, and is resistant to rancid attack by bacteria. When used as directed, VpCI®-347 prevents corrosion during in-plant processing, storage, and export shipment for up to 24 months, while also eliminating problems caused by petroleum-based products.

FEATURES
• Low to no smoke or burning vapors
• Low foaming
• Prevents corrosive attack caused by chlorides, aggressive industrial
gases and acidic atmospheres
• Effective in high humidity (laboratory tests of standard cold-rolled
steel panels showed no signs of corrosion at 100% relative
humidity after 2,000 hr. per ASTM D-1748)
• Provides excellent drawability, lubricity and wetting under pressure
• Displaces water and oil from metal surfaces, leaving a thin
transparent film
• Economical (can be diluted up to 1 part VpCI®-347 to 40 parts
water)
• Protects ferrous and non-ferrous metals
• Easy to remove from metal surfaces
• Contains no chlorinated compounds, chromates, or nitrites
• Eliminates cleaning and housekeeping problems associated with
rust inhibiting oils
• No need for slushing oils
• Weldable in most cases.
• Resistant to rancid attack by bacteria
• Forms a transparent film
• NATO #6850-66-132-6101
#6850-66-132-6102
• NSN 6850-01-470-2740

TYPICAL APPLICATION
• Lubricant for heavy-duty rolling, drawing, extruding, stamping
and cutting
• In-plant machining
• Protection of hot-rolled, cold-rolled, galvanized, and aluminized
steel
• Corrosion protection for bearings, piping and tubular parts,
housings, stampings, bar and roll stock, and structural steel
during in-plant storage or domestic and export shipments
• Coolant for machining of castings, highly polished pieces and
other parts; providing superior protection between machining
operations and further processing or assembly
