Product Uses
  • NA-SUL® BSN is used in a wide variety of industrial lubricant applications where excellent rust protection and water resistance are required. It imparts outstanding demulsibility and is unique in that the water separation improves as the NA-SUL® BSN concentration is increased which allows high treat levels for severe rust protection requirements.
  • NA-SUL® BSN is the most widely used rust inhibitor in all types of greases. In rust preventive fluids, the excellent resistance to metal staining is an added feature.
  • NA-SUL® BSN is also well suited for premium hydraulic oil formulations.
  • Barium dinonylnaphthalenesulfonate is also available in alternative diluents, including PAO and esters for synthetic lubricants, and mineral spirits and waxes.
