Rust Conversion Agent D121

Rust Conversion Agent D121

Product Overview:

Rust Conversion Agent D121 is primarily composed of organic macromolecular chelates that can chemically react with rust to produce black metal chelates that firmly adhere to iron substrates. When used, it is added to an acidic emulsion to create a rust conversion coating, eliminating the need for rust removal and allowing direct application to rusted steel surfaces. It forms a dense gray-black rust-protective coating through a complexation reaction with rust, solving the issues of traditional methods being complex and environmentally unfriendly.
