RUST CONVERTER A "rust converter" is a chemical treatment used to convert iron oxide (rust) into a more stable compound that can protect metal surfaces from further corrosion. Here's how it typically works: 1. Chemical Reaction: Rust converters contain active ingredients that chemically react with iron oxide (rust) on the surface of metal. These ingredients usually include tannic acid or phosphoric acid. 2. Conversion Process: When applied to a rusty surface, the rust converter interacts with the iron oxide, creating a stable compound called iron tannate or iron phosphate. This stable compound is typically black in color. 3. Protection: The newly formed compound acts as a protective barrier on the metal surface. It helps prevent further oxidation of the metal by sealing out moisture and oxygen, which are necessary for rust formation.
