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 multimetal systems requiring vapor phase and contact protection. Causes little to no foam. 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 liters) pails, 55 gallon (208 liters) 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 multimetal contact and vapor phase corrosion protection to synthetic cutting fluids and water-based hydraulic fluids. Package: 5 gallon (19 liters) pails, 55 gallon (208 liters) drums, liquid totes, and bulk.
