TRANSENE SULFITE GOLD - TSG-250
Gold Electroplating Solution for Electronic and Aerospace Applications

DESCRIPTION:

TSG-250 is a ready-to-use, cyanide free stabilized gold sulfite electroplating solution which deposits soft satin-bright electrodeposits. The solution exhibits a slightly acid or neutral pH for applications where high pH is undesirable. TSG-250 meets Type IIIA of Mil-G-45204 C requirements.

OPERATING CONDITIONS:

Temperature

110-160°F (140° F 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)

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 30° Baume precipitate sulfate using calcium acetate or barium acetate to lower the SPG to a working range.
