Rust Converter
Rust converters are chemical additives that convert iron oxides into stable metal complexes, thus preventing corrosion. They are used before a new paint application.
Physical-Chemical Mechanism of Action
Rust converters are organic acids or polymers that convert iron oxides into stable metal complexes. This prevents the oxides from further corroding and forming on the surface.
Metallurgical Relevance & Welding Risks
If iron oxides are not neutralized, they can lead to cracking or corrosion, especially in humid environments. Rust converters prevent these processes and ensure a clean surface for paint application.
Workshop Practice & Instructions
Before starting a new paint job, iron oxides must be neutralized. This is done by applying a rust converter spray or a suitable liquid. The surface must be thoroughly dry and free of residue to ensure optimal paint adhesion.
