APPLICATIONS: TSG-250 is ideal for applications where high pH plating solutions react with exposed materials or if a non-cyanide bath is desired. One troy ounce of gold is plated every four amp-hours. The specific gravity of the bath rises with use. Above 30o Baume precipitate sulfate using calcium acetate or barium acetate to lower the SPG to a working range.
