VC-RUSTOMIT Rust Converter VC-RUSTOMIT is a dark brown liquid rust converter, designed specifically for rusted iron and steel surfaces. When applied, it chemically transforms rust into a hard, blue-black protective coating, providing a stable base for further protection or painting * How Rust Converters Work ? 1. Rust converters contain tannic acid and phosphoric acid, which react with rust to form a black protective layer (iron tannate or iron phosphate). This eliminates the need for extensive rust removal. * Types of Rust Converters 1. Tannic Acid-Based Rust Converters - Reacts with rust to form iron tannate (black, stable layer). - Ideal for mild to moderate rust. - Can be painted over once dry. 2. Phosphoric Acid-Based Rust Converters - Converts rust into iron phosphate, which improves paint adhesion. - May require rinsing after application. - Common in industrial and automotive applications.# VC-RUSTOMIT Rust Converter Manufacturer.
