VpCI® Additives for Metalworking and Hydraulic Fluids

Cortec® offers a variety of additives for use with metalworking and hydraulic fluids. These additives protect metal pieces from flash corrosion during the metalworking process, while also providing protection to the cutting and machining equipment. Other additives can be used for preserving important hydraulic equipment during shipping or storage. A range of vapor phase protection capabilities adds an important dimension to protecting parts with void spaces.

  • M-95: Versatile water soluble additive for various multi-metal systems requiring vapor phase and contact protection. Causes little to no foam. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-235: Prevents corrosion of yellow metals. Can be added to functional fluids such as hydraulic fluids, specialty lubricants, automotive coolants, and metalworking fluids. Package: 5 pound (2.3 kg) pails, 50 pound (23 kg) and 100 pound (45 kg) fiber drums.
  • M-236: Liquid corrosion inhibitor especially designed for oils and solvent-based products in contact with yellow metals. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-241: Corrosion inhibitor for aluminum. Add to metalworking fluids and water-based coolants. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-250: Anti-corrosion additive with emulsification properties for soluble oils. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-251: Adds multi-metal contact and vapor phase corrosion protection to synthetic cutting fluids and water-based hydraulic fluids. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-320: Provides vapor and contact protection to oil systems such as gearboxes. Recommended during layup. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-370: Multi-metal corrosion preventive additive for water-based metalworking fluids. Prevents flash corrosion on metal surfaces and forms a hydrophobic film that is virtually undetectable when dry. Also available in A (aluminum), NS (non-surfactant), HS (high surfactant), and C (additional protection for cast parts and rough surfaces) versions. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-528: Additive to hydraulic fluids for corrosion protection in subsea systems. Also for synthetic coolants and cutting fluids. M-528 L includes lubricant. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-415: Strong vapor phase corrosion inhibitor additive for oils and fluids. Contains FDA and USDA approved ingredients. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
