ANO SEAL C200 is the most improved sealing agent which carries out the final sealing treatment at low temperature for all the anodized coating. In order to seal the fine foam of the hexagonal cell which is derived by the anodizing treatment the past technology is usually dependent on formation of the boiled water and the relation of metal-salt.

Even if the completely sealed coating shows better corrosion-resistance and stripping resistance than that of the anodized treatment only. In order to obtain these effects, it is related with the time of the sealing treatment of the boiled water and the temperature. Also, the most disadvantage of the past sealing treatment is the adherence of the white powdering which is called as "bemite smut" after treatment. This "smut" is very apparently ugly. In general, to remove this, it needs so many efforts.
