Acidic type rust remover for copper (discoloration removal) agent
This is an acidic type rust remover (discoloration remover) for copper. 【Features of KC-12A】 ● It is mainly composed of phosphoric acid, which has less impact on the human body and surrounding metals compared to hydrochloric acid and nitric acid. ● It can treat rust in a short time (1 to 10 minutes) without damaging the surface of copper or brass. ● It can be diluted with water (2 to 10 times) and is non-flammable and non-explosive. 【Features of Mekarins Cu-940】 ● It removes the oxide film from the surface of brass in a short time (20 seconds to 2 minutes). ● It results in a good glossy finish. ● It maintains its shine even after washing with water. 【Features of Mekarins Cu-980】 ● It removes the oxide film from the surface of copper. ● It results in a good glossy finish. ● It maintains its shine even after washing with water.

Applications/Examples of results
**[KC-12A Applications]** - Rust removal from parts and products generated during the manufacturing process (copper, brass materials) - Rust removal generated during wire electrical discharge machining (copper, brass materials) - Pre-treatment before painting, plating, etc. - Rust removal from copper and brass materials **[Mekarins Cu-940 Applications]** - Removal of oxidation film from brass **[Mekarins Cu-980 Applications]** - Removal of oxidation film from copper **[KC-12A Usage Instructions]** 1. Immerse the rusted workpiece in the product (undiluted to 10 times diluted solution). 2. As soon as the rust is removed, rinse thoroughly with water. 3. The metal surface after rinsing is prone to rust again, so please use a rust inhibitor specifically for copper materials (such as our CP-CU). **[Mekarins Cu-940/Cu-980 Usage Instructions]** 1. Immerse the workpiece in the undiluted solution. 2. The oxidation film and corrosion will be removed in a short time (5 to 30 seconds), so immediately remove the workpiece and rinse thoroughly with water. 3. The metal surface after rinsing is prone to rust again, so please use a rust inhibitor specifically for copper materials (such as our CP-CU). *For further details, please contact us.*
