What is a rust inhibitor?

Rust or corrosion inhibitors are chemicals usually added to an oil or grease to help decrease the corrosion rate of metals(generally, iron，steel and other ferrous metal). These chemical additives are also called: anti-rust additives, rust inhibitors, rust preventives, rust preventative and corrosion inhibitors.

Generally rust inhibitors are divided into five categories: sulfonates, carboxylic acids and carboxylic acid derivatives, esters, organic phosphates and salts, organic amines and heterocyclic compounds.
Sulfonates, is one of the main metal surface treatment additives. such as barium petroleum sulfonate, sodium petroleum sulfonate, sodium alkylbenzene sulfonate, barium dinonylnaphthalene sulfonate, zinc dinonylnaphthalene sulfonate, Neutral calcium dinonylnaphthalene sulfonate, etc. These sulfonate type corrosion inhibitors can be firmly adsorbed on the metal surfaces to form a protective film with anti-rust performance.

Where are rust inhibitor additives used?

The rust inhibitor additives are widely used in engine oils, industrial lubricants, Metal Working Fluids, and rust prevention oils.
e.g. Rust Inhibitor Zinc Dinonylnaphthalene Sulfonate (Chorus Zn-29N) is very suitable for various lubricant oils (hydraulic oils) if water resistance is required because it has excellent demulsibility.
e.g. Chorus supplies corrosion inhibitor packages for the formulation of rust-preventive oils, Temporary corrosion protection ( Temporary anti-rust treatment for metal parts in manufacturing industries)

How do the rust preventive Chemicals work?

The molecules of rust-preventive chemicals tend to bind to the metal and create a protective layer that blocks the metal surface from water, acids, and oxidation to prevent rust for a wide range of metals.

FAQ - Rust Inhibitor Additives in Lubricants and MWF

Q: How does rust preventive additive work?

A: Rust-preventive oils consist of rust-inhibitors and base oils, These rust-inhibiting chemicals have strong polar that bond to the metal surface and create a preventive coating around the metal to prevent the water and air from corroding the metals.

Q: How to evaluate the performance of rust-preventives?

A: Generally, we test the rust prevention performance as per 2 test methods. Humidity Cabinet Tests & Salt Spray Tests.

These tests simulate and accelerate the corrosion speed, and we may get the corrosion performance in a much shorter time and predict the rust-preventive. If we want the rust-prevention performance test result in the real environment. we may need months or even years. Image that we place one steel sheet with rust-preventive oil coated in a room and check the rust regularly.

Q: Is rust inhibitor hazardous?

A: Chorus rust inhibitors are industrial chemicals designed to prevent rust and corrosion on steel, aluminum, and other metals. Most of these rust inhibitor additives are not considered dangerous goods. For detailed, please contact us for the MSDS.

Q: Is rust inhibitor eco-friendly?

A: Chorus supplies industrial rust inhibitor additives free of barium and other heavy metals. These chemicals work to prevent rusting and they are environmentally friendly.

Q: What are the testing standards for rust preventive performance?

ASTM B117 - Salt Spray Fog Testing

ASTM D1748-2012《Standard Test Method for Rust Protection by Metal Preservatives in the Humidity Cabinet》

ISO 3613-1985《Corrosion tests in artificial atmospheres — Salt spray tests》

DIN 50960-2001《Testing of metallic and non-metallic materials -- Corrosion testing in artificial atmospheres -- Salt spray tests》

JIS Z 2371-2007《Testing methods for hard coating films -- Salt spray test》

Q: I want to produce rust-preventive oils, do you have a recommended formulation?

A: Chorus supplies corrosion inhibitor packages for the formulation of rust-preventive oils. Users only need to blend the corrosion-preventive packages into the base oil as per the instructions to get the wanted anti-rust oils that are widely used in the manufacturing industry.

Q: May I ask for a customized anti-rust additive product?

A: Yes, even though we have a series of anti-rust additives in our product portfolio, we understand and respect the client's unique demand for the local market. Please contact us about your customized anti-rust products.

Q: May I have a sample of rust inhibitor?

A: Yes, you are welcome to contact us for a sample of rust & corrosion inhibitor. Chorus company understands the importance of product testing and strive to make the anti-rust additives sample delivery process as straightforward and reliable as possible.

Q: What is the package of rust inhibitors?

A: 200L Steel drum or IBC, and other customized packages. For the detailed packing of rust-inhibitor, please do not hesitate to contact our sales engineer.

Q: What is the MOQ for rust inhibitors? and the rust inhibitors price？

A: The minimum order quantity of Chorus Rust Inhibitors are one pallet( 200kg * 4 drum), or one IBC (1000kg). There are many types of rust inhibitors, please contact us for the detailed price.

Q: What is the standard delivery time for your rust inhibitors

A: Generally, we need an estimated 7-15 days to produce and deliver the rust inhibitors to the dispatch port. For customers, you may receive the goods in about one month if the ship on sea time is 20 days

Q: What is the shelf life of your corrosion inhibitor?

A: Generally, the shelf life of corrosion inhibitor additives lasts for 2 years, even If beyond the storage period, it can still be used after passing the quality test.
