M-251 Additive to Synthetic Cutting Fluids
M-251 is an environmentally friendly , low foaming water soluble corrosion inhibiting additive for synthetic cutting fluids. It provides corrosion protection to carbon steel, copper, galvanized steel, and other ferrous and nonferrous metals and their alloys. M-251 provides both contact and vapor phases corrosion protection during and after operation.M-251 is compatible with most water-based lubricants and with a range of biocides. It is compatible with sea water, which allows the use of this additive in off-shore conditions.
As an additive to synthetic cutting fluids M-251 should be added in the following concentrations:
Operation and short term (up to 30 days) protection after the operation - 0.75-1.0%
Operation and longer term (up to 90 days) protection after the operation - 1-5%
Operation with salt water - 2.5-5%
Operation with salt water and short term of protection after the operation - 5-10%Other applications:
• Water-based lubricants
• Alkaline metal cleaners
• Water-based drilling muds
• Water-based hydraulic fluids
M-251 is available in 5 gallon (19 liter) plastic pails and 55 gallon (208 liter).M-251 has to be stored sealed in a heated warehouse to avoid freezing. The shelf life is 24 months.
