Rust Converter for Metal
- Rust converters are chemical solutions designed to chemically convert iron oxide (rust) into a stable, paintable surface, typically a black or dark protective coating like iron tannate or ferric phosphate. They’re ideal for treating rusted metal surfaces without full sandblasting, especially when prepping for painting or sealing.
* How Rust Converters Work
- Rust converters typically contain:
- Tannic acid – reacts with iron oxide to form black ferric tannate, a stable compound.
- Phosphoric acid – converts iron oxide into iron phosphate, which provides a paintable surface.
- Some formulas include polymer binders to form a primed surface ready for topcoating. # Rust Converter Manufacturer.
