VpCI®-345 is a premium water-based metalworking lubricant concentrate for difficult-to-produce metal stampings, tubular products, and machined parts. VpCI®-345 is superior to petroleumbased coolant rust preventives. When used as directed, VpCI®-345 prevents corrosion during in-plant processing, storage, and export shipment up to 24 months. VpCI®-345 is ideally suited for lightduty machined and polished parts requiring long-term corrosion and surface protection. VpCI®-345 can be effectively used as a coolant in machining applications where maximum cooling is employed. Highperformance characteristics of VpCI®-345 make it ideally suited
for light-duty cutting, milling, turning, drilling, boring, broaching, gear cutting, and other machining operations. VpCI®-345 can replace neat oils and semi-synthetics when there is a requirement for maximum coating and superior rust inhibiting stability. VpCI®-345 is resistant to rancid attack by bacteria. Product life is the same or longer than similar machining fluids.

TYPICAL APPLICATIONS
• In-plant machining
• Protection of hot-rolled, cold-rolled, galvanized, and aluminized
steel
• Coolant for machining of castings, highly polished pieces, and
other parts; providing superior protection between machining
operations and further processing or assembly

METAL PROTECTED
• Carbon steel
• Stainless steel
• Aluminum
• Galvanized steel
• Zinc
• Cast iron

FEATURES
• Unique Vapor phase Corrosion Inhibitor action protects uncoated
and difficult-to-reach areas in castings and stampings
• Excellent wetting
• Economical – VpCI®-345 can be diluted with up to 40 parts water
• Protects ferrous and non-ferrous metals
• Easy to remove from metal surfaces with alkaline cleaners
(VpCI®-410 series)
• Does not contain flammable solvents, reducing fire hazards
• Contains no chlorinated compounds, chromates, or nitrites
• Eliminates cleaning and housekeeping problems associated with
rust inhibiting oils
• Gives protection to parts after completion of metalworking
operations, thus eliminating the need for further applications
of rust preventives
• Rancid stability and resistance to bacterial attack
• Passes ASTM D 4627-86 (Test Method for Iron Chip Corrosion
for Water-soluble Metalworking Fluids) at 2.5% by weight
• Weldable
