Features & Benefits
- Features
- When dissolved in a 5% Sulfuric Acid Solution, a clear solution is obtained.
- Gradual hydrolysis occurs over a period of time with the formation of insoluble tin compounds.
- Many stannate tin platers have converted to acid sulfate.
- Room temperature operation, expedited reaction, greater anode efficiency, and a bright finish or matte finish options may be listed among the advantages.
- The inception of acid sulfate electroplating was in the electronics industry.
- Currently, however, any plater untroubled by the hydrogen embrittlement will utilize an acid sulfate process.
- Because the anode provides all the necessary tin, only a minimal quantity of Stannous Sulfate is requisite in order to maintain the plating bath.
- Thus, there is a profusion of companies of modest capacity with a requirement for electroplating Stannous Sulfate.
- The recently expanded market for Stannous Sulfate has developed during the past 15 years.
- Color anodizing aluminum for architectural or automotive applications has become a major outlet for Stannous Sulfate.
- Two binary procedures are employed. In both of these two step processes either all or one half of the tin emanates from the sulfate.
- One process utilizes inert electrodes, and the other uses tin electrodes.
- Therefore, the sulfate consumption varies.
- Almost one half of the Stannous Sulfate consumed in the United States is for color anodizing.
