Rust converter

Stop rust with nC Corrosion Passivator

Rust is a common issue that can deteriorate the lifespan of metal surfaces and coating systems. Fortunately, there is an effective solution: rust converter. On this webpage, we discuss what a rust converter is, how rust converters stop rust, and introduce the sustainable rust converter nC Corrosion Passivator Primer 2-in-1.

What is a rust converter?

A rust converter is a chemical product designed to transform rust (iron oxide) into a stable compound. This process stops the corrosion process and prepares the steel surface for further treatment, such as painting or coating. Rust converters are typically available in liquid form but can also be found in spray form, depending on the application. Not all rust converters are the same; they vary in composition, functionality, and protective lifespan.

How does a rust converter work?

Rust converters work by chemically reacting with the rusty surface. The active ingredients in the rust converter react with iron oxide to form a protective layer. This layer adheres to the metal and prevents further exposure to moisture and oxygen, the two primary factors that cause rust.

Benefits of using a rust converter

Corrosion Passivator Primer 2-in-1
  • Ease of use Rust converters can be applied easily with a brush, roller, or spray, depending on the product type. They require minimal preparation and can be applied directly to rusty surfaces.

  • Cost-effective – Using a rust converter can save significant costs by extending the lifespan of metal objects and structures. It reduces the need for extensive rust removal techniques like sanding, blasting, or scraping.
  • Protection and maintenance – Once applied, a rust converter provides protection against further rust formation, making it an ideal choice for preventive maintenance of metal surfaces.

nC Corrosion Passivator Primer 2-in-1

Effective and Long-Lasting Rust Protection In addition to traditional rust converters, nC Corrosion Passivator Primer 2-in-1 offers an innovative approach to rust conversion and protection. This advanced solution is specially formulated for direct-over-rust applications on metal surfaces. It eliminates the need for intensive preparation such as sanding or blasting, saving time and costs.

Our biochemically-based alternative is oil-based and penetrates deeply into steel. Thanks to the depot action of the formula, new rust is also passivated when moisture and oxygen enter due to damage, for example.

Our corrosion passivator primer 2-in-1 is a proven solution in inland and maritime shipping. In demanding maritime and industrial environments, our products provide a suitable direct-over-rust solution that eliminates the need for chipping or blasting.
