- Product Uses
- NA-SUL® 729 is used in a wide variety of industrial lubricant applications where excellent rust protection, filterability and water resistance are required. It imparts outstanding demulsibility and is unique in that the water separation improves as the NA-SUL® 729concentration is increased which allows high treat levels in applications with the most severe rust protection requirements.
- NA-SUL® 729 is highly recommended for use in hydraulic fluids meeting the Denison HF-0 specification.
- It is also widely used as a rust inhibitor in most types of greases. In rust preventive fluids, it exhibits excellent synergism with other functional additives such as oxidates, waxes and carboxylates.
- NA-SUL® 729 can also be used in emulsifiable rust preventive fluids.
- Calcium dinonylnaphthalenesulfonate is also available in alternative diluents, including PAO and esters for synthetic and environmentally acceptable lubricants and in mineral spirits and waxes.
