RUST CONVERTER - A rust converter is a chemical solution that reacts with rust (iron oxide) and converts it into a stable, black protective coating, preventing further corrosion. It is commonly used in industrial, automotive, and marine applications. * How Rust Converters Work 1. Rust converters typically contain: Tannic Acid – Reacts with iron oxide to form iron tannate (a stable, black protective layer). Phosphoric Acid – Converts rust into iron phosphate, which acts as a primer for painting. Polymer Resins – Help seal and protect the treated surface. 2. How to Apply a Rust Converter Surface Preparation – Remove loose rust, dirt, grease, and oil using a wire brush or degreaser. Application – Apply with a brush, roller, or spray (depending on the product instructions). Drying Time – Most rust converters take 24–48 hours to fully cure. Painting (Optional) – Once dry, the treated surface can be painted for added protection. # RUST CONVERTER Manufacturer.
