Can Rust Stop Oil Additives Really Halt Rust Spread?

Metal rusting is a common problem that causes losses of over a hundred billion US dollars in the global industrial sector every year. Rust is caused by the oxidation reaction of metals with water and oxygen. The rust layer is loose and porous, which can increase the continuous corrosion of the internal metal and the rust layer permeability as high as 80%. And when the humidity and salt content of the rust environment increase, the rate of metal corrosion will rise significantly.

As the ASTM B117 salt spray test indicates, the corrosion rate in a salt-containing environment will increase by 3 to 5 times. According to the research by NACE (National Association of Corrosion Engineers), the corrosion rate in a humid environment is 5 to 10 times faster than in a dry environment.

To prevent metal rust, anti-rust oil and rust stop oil additives are needed. Iron sheets coated with general mineral lubricating oil will rust after being placed in a damp box for several hours. However, the iron sheets with rust-stopping oil additives have an anti-rust lifespan of over 1,000 hours. As one of the common methods of preventing rust, anti-rust additives are usually used for rust inhibition. But can rust stop oil additives from really halting the spread of the existing rust?

The Principle of Rust Stop Oil Additives

The anti-rust additive dissolves in the oil as micelles. When it contacts the metal surface, it forms a firm and closely arranged adsorption film on the metal surface. And the base oil molecules are interspersed in the gaps between polar molecules, forming a mixed multi-molecular layer protective film, to prevent water and oxygen from eroding the metal.

The guidance on using Rust Stop oil additive

Use Cases of Rust Stop Additives

Rust stop oil additive is suitable for metal surface cleaning, rapid drying, and a short rust prevention cycle, especially suitable for oil-sensitive industries, such as rust prevention between processes, electronics, and automotive parts.

After processing the parts, the automobile manufacturing plant uses water-based rust inhibitors for spray treatment to form a non-greasy protective film. The anti-rust additives form a dense oxide film through a chemical reaction. The rust preventive additives can dry at room temperature in 4 hours, and cure at high temperature (60℃) in just 3 to 5 mins. There is no evident rust after the treatment of metal components and being stored in a humid environment for 3 months, and it doesn't influence the subsequent welding or painting process.

Use Cases of Rust Stop Oils

Rust stop oils are suitable for high humidity and salt spray environments like maritime transport and outdoor storage, which require a thick film for long-term rust prevention.

The ship engine components exported to Southeast Asia are sealed with rust-preventing oil. Though the ASTM B117 salt and spray test, 6 months later, the corrosion area is less than 5%. And it has passed the ISO 9227 moisture-heat aging resistance verification and can resist the corrosion of the marine climate.

Rust Preventive Additive Chorus-2100

Chorus-2100 has good performance of water displacement and anti-salt spray, which can provide excellent rust-preventive films for non-ferrous metals and ferrous metals that are exposed to a corrosion environment. It's environmental protection and is applied in various sectors of the manufacturing industry.

Chorus-2100 is suitable for formulating different rust stop oils and has the features of easy operation and low costs.

Anti-rust Additive Package Chorus-2028S

Chorus-2028S has good solubility and wide application, which is used in a variety of mineral oils and solvent oils. It's mainly used as a metal inhibitor and corrosion inhibitor for metal products and the preparation of anti-rust oil.

Conclusion

Chorus is a lubricating oil supplier in China and can provide you with different functions of rust stop oil additives. These additives are easy to use, and anti-rust oils with different durations can be formulated by adding different proportions of rust preventive additives, which can prevent the occurrence of rust on metal products. Through reasonable blending, it can be applied to short-term or medium to long-term rust prevention in high humidity and salt spray environments. Although anti-rust oil can prevent rust effectively, it can only temporarily suppress existing rust and needs to be combined with cleaning or rust treatment.
