Rust Inhibitor Neutral Calcium Dinonylnaphthalene Sulfonate Antirust Additive
Introduction of Rust Inhibitor
Neutral calcium dinonylnaphthalene sulfonate (Chorus-CA729) is an excellent oil-soluble anti-rust additive and anti-emulsifier, widely used in various industrial lubricant applications where rust protection and water resistance are required.
Its chemical structure and properties are similar to neutral barium dinonylnaphthalene sulfonate (Chorus-BSN), and it can replace Chorus-BSN in some places where the use of barium compounds is restricted.
Applications of Rust Inhibitor
Work as anti-rust and anti-emulsifier additives in internal combustion engine (ICE) oil, hydraulic oil, paper machine oil, instrument oil, circulating oil, etc.
