Product Uses
  • NA-SUL®CA-50 is a versatile rust and corrosion inhibitor used in all types of industrial lubricating oils. It is extremely effective against fresh water and salt water corrosion, thus, making it an ideal choice for use in post tensioning greases and rust preventive fluids.
  • NA-SUL® CA-50 is also used in extreme pressure lubricants where it provides superior rust protection and acid neutralization. As a result of its alkalinity, NA-SUL® CA-50 works as an HCl scavenger when used in combination with chlorinated paraffins to avoid rusting of newly machined metal parts.
  • NA-SUL® CA-50 can also be used for formulating military hydraulic oils that have to provide outstanding demulsibility and extremely effective rust protection under humid conditions. NA-SUL® CA-50 is also used in high performance dewatering fluids.
