Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

During the 1940 and 1950s it was typically found as the "paint" in the wheel wells of retractable landing gear on US military aircraft to protect the aluminium from corrosion. This compound was a useful coating because it is an anti-corrosive and anti-rust primer. [8] Since it is highly toxic, it also destroys organic growth on the surface.
