Product Uses
  • NA-SUL® 611 is a high molecular weight basic barium sulfonate which provides improved oxidation stability to formulated lubricants due to its reserve alkalinity. It is used in petroleum and synthetic lubricating oils, greases and rust preventive fluids.
  • NA-SUL® 611, due to its chemistry, is particularly effective as an additive in polyglycol/ester based compressor lubricants.
  • It is also useful for formulating turbine oils, hydraulic oils, paper machine lubricants, instrument oils and circulating oils.
  • It has good acid neutralizing and deactivating properties. As a result of its alkalinity, NA-SUL® 611works as an HCl scavenger when used in combination with chlorinated paraffins to avoid rusting of newly machined metal parts.
