Features and Benefits

 N/A
  • Optimized combination of cooling and lubricity
  • Superior resistance to corrosion on both nonferrous and ferrous materials
  • Extremely low foaming in chilled environments
  • Meets the most stringent nuclear and aerospace chemical content and machining requirements
  • Provides superior results in a wide range of operations from general grinding to spar milling and turbine blade manufacture
  • Easily removed from parts for easy cleanup before assembly, painting, or plating operations
  • Very low carryoff and long sump life results in low operating cost
  • Free of: boron, chlorine, copper, nitrites, phenols, SARA 313 listed ingredients, silicone, and triazine

Additional Information

 N/A
  • Higher concentrations of C390 increase both boundary and EP lubrication.
  • Very low foam at working temperatures above 60˚F (16˚C).
  • Maintaining concentration from 7.5% to 10% provides the best sump life and corrosion inhibition.
  • C390 is not recommended on cast irons.
  • C390 should not be used on magnesium or other reactive metals without special precautions.
