Kyros CORROBAN® Unprotected bright metal surfaces are often destroyed by corrosion, particularly through oxidation. Corrosion has an adverse effect on the appearance of metal and it may even interfere with the smooth operation of a machine. Volumetric size of rust is greater than that of the iron from which it is formed and this leads to the creation of surface roughness. It also results in formation of blisters on rusted surfaces. Corrosion preventives are used to protect metal surfaces against atmospheric effects in the widest sense and prevent the conversion or chemical degradation of metals into their compounds, particularly to their oxides. In general, corrosion would cause a huge damage or loss and the effort and expense involved in applying effective surface protection is only a small fraction of the total cost of the damage.
