TRANSENE SULFITE GOLD
TSG-250
TSG-250 is a ready-to-use, cyanide free stabilized gold sulfite electroplating solution which deposits soft satin-bright electodeposits. The solution exhibits a slightly acid or neutral pH for applications where high pH is undesirable. TSG-250 meets Type III of Mil-G-45204C requirements.
PROPERTIES :
| Temperature | 43.3-71.1℃ (60℃ optimum) | 
|
| Current Density | 1-8 ASF |
| Anode | Platinized |
| Anode to Cathode Ratio | 1:1 minimum |
| Agitation | 100% efficiency-vigorous |
| pH | 6.0-7.0 |
| SPG | 10-30° Baume |
| Tank | Polypropylene, Glass, Fiberglass |
| Hardness | 60-70 knoop as plated (may be annealed) |
APPLICATION :
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 30° Baume precipitate sulfate using calcium acetate or barium acetate to lower the SPG to a working range.
