ECOS-R421™ is a specially formulated, biodegradable metal cleaner/scale remover, containing no hazardous solvents and diluted with water to meet a wide range of industrial cleaning applications. Typical applications for this product include various coolants, pipes, machine parts and engines. Materials that can be removed include metals containing oxides (aluminum alloy, zinc, steel, copper, etc).
ECOS-R421™ contains a strong corrosion inhibitor, so no corrosion or damage to the surface of the material occurs.
How to check corrosion: In the case of common organic and inorganic acid rust removers for carbon steel, Smut, a cementite phase material (Fe3C), is generated on the surface after treatment. If the surface turns black in color, the surface of the base material is corroded. Before applying the rust remover, a preliminary corrosion test should be carried out.
