Carbonated Basic calcium dinonylnaphthalene sulfonate (Chorus-CA-50) is an excellent oil-soluble anti-rust additive with an alkalinity reserve.
Its chemical structure and performance are similar to neutral calcium dinonylnaphthalene sulfonate (Chorus-CA729), but the product contains oil-soluble nanometer-dispersed calcium carbonate(CaCO3). It has the ability to neutralize the acid components in the lubricant.

Chorus-CA-50 is widely used in industrial lubricant oil as a rust and corrosion inhibitor.
It works as an anti-rust additive in extreme-pressure lubricants. It has a certain effect in improving the extreme pressure performance of oil products.
1. Packed in 200L metal drum, IBC tank, or made to order.
2. Long-term storage temperature should not exceed 45ºC.
3. Handle & blending temperature should not exceed 65ºC.
4. Not dangerous chemicals, store in a dry & clean warehouse.
What Is an Rust-preventive Additive In Lubricant and Metalworking Fluid?
Anti-rust additives are chemical compounds incorporated into lubricants and metalworking fluids (MWF) to protect metal surfaces from corrosion. The anti-rust additive is also called: rust inhibitor, rust preventive, and corrosion inhibitor. They are wily used in engine oils and MWFs.
Classification Of Anti-Rust Additives
Generally, according to the characteristics of the solution, Rust Preventives can be divided into water-soluble Rust Preventives, oil-soluble Rust Preventives, emulsified Rust Preventives, gas-phase Rust Preventives, and wax film-type Rust Preventives.
Sulfonates, the general chemical formula is (R-SO3) metal surface treatment additives. Generally, alkali metal or alkaline earth metal salts of petroleum sulfonic acid are used, such as barium petroleum sulfonate, sodium petroleum sulfonate, barium dinonylnaphthalenesulfonate, etc.
