CooVar Rust Converter - 250ml
Coo-Var Rust Converter is for use on iron and steel surfaces where all rust cannot be removed. Will stop the rusting process and allow for the surface to be overcoated.
What is Rust converter?
A rust converter is a chemical solution that reacts with rust (iron oxide) to form a stable, inert compound that can be painted over. It transforms the rust into a black, protective coating, preventing further corrosion.
How does Rust converter work?
Rust converters typically contain tannic acid and an organic polymer. Tannic acid reacts with the iron oxide (rust) to form a stable iron tannate, while the polymer provides a protective layer. This process stops further rusting and prepares the surface for painting.
