C-48 Cadminum Brightener
DESCRIPTION:
Triple-s C-48 Cadmium brightener, is a liquid addition for cyanide cadmium plating solutions. Triple-s C-48 Cadmium brightener produces brilliant deposits over a wide range of current density.
ADVANTAGES:
- Low cost
- Easy to operate, trouble free
- Produces very bright uniform deposits
- Exceptional throwing power and covering even in processed areas
- Very stable brightener
- Works for rack and barrel solutions
- Increases plating speed
- Accepts easily a clear passive treatments by using 148-C Bright Dip

PREPARATION OF NEW SOLUTION:
- Fill the tank about ¾ full with water.
- Dissolve the required amount of Sodium Cyanide.
- Dissolve the required amount of cadmium oxide by stirring solution vigorously.
- Caustic soda will be formed by dissolution of sodium cyanide and cadmium oxide. Each ounce/gal. of cadmium oxide produces 0.63 oz./gal. of caustic soda. Therefore, it is necessary to deduct it from the amount of Caustic soda to be added to a new solution.
- Add triple-s C-48 Cadmium Brightener. The required amount of C-48 should be diluted with two parts of water.
- Add water to bring the solution to the operating level.
CONVERSION OF EXISTING SOLUTIONS:
Most conventional cadmium solutions or bright cadmium baths are easily converted to Triple-s C-48 Cadmium Brightener, by adjusting the solution and adding the required amount of C-48. However, it is suggested that one quart sample be sent to our laboratories for free analysis and recommendations.
MAINTENANCE CONDITIONS:
- As indicated above, for a new bath, the addition of one gallon per 100 gallons is required.
- For each 10 pounds of Cyanide added, add one pint of C-48 Brightener. This method is recommended, supplemented by Hull Cell tests.
- By Hull Cell tests-entire length of the panel should be bright.
- It is important to maintain a small amount of Caustic Soda in the Cadmium bath. Prolonged operation with insufficient Caustic soda is evidenced by solution taking on a chocolate-brown color. In this case, it may be necessary to carbon treat, add the required amount of Caustic Soda and then add additional C-48 Brightener.
- Cyanide contents must be held within limits. Too high cyanide is indicated by dulling at high current density areas, low cyanide causes poor throwing power and covering; moreover, low cyanide causes anode polarization.
- Sodium Carbonate above 8 oz./gal. will cause a very narrow bright plating range. Under normal conditions, carbonate build up is very slow. The so-called freezing method is preferred for removal.
- Staining can best be avoided by using a 148-C Bright Dip chromate. For specific recommendations, contact Triple-s Chemical Products, Inc.
EQUIPMENT REQUIRED:
- TANKS: Steel tanks are satisfactory for Cadmium solution, rubber-lined steel tanks can also be used to advantage, because current can be directed to the work with greater certainty of even metal distribution. Moreover, there will be no danger stay current.
- RACKS: Steel or copper racks may be used. To conserve metal and current, as well as to prevent contamination of the solution, the racks should be coated with a suitable insulating rack coating.
TOXICOLOGY:
The plating solution is highly hazardous, it may be fatal if swallowed or inhaled and will cause irritation to skin and eye on contact. It is recommended to avoid any physical contact and wearing chemical safety gloves, glasses and clean protective outer clothing. Provide adequate ventilation to prevent inhalation of vapor or solution spray.
SUGGESTED FIRST AIDS:
Plating solutions: In case of eye contact: Immediately flush eyes with plenty of water for at least 15 minutes and call a physician.For skin Contact: Wash with water for at least 15 minutes while removing contaminated clothing. Obtain medical attention. If swallowed, break an AMYL Nitrate pearl in a cloth and hold lightly under the nose for 15 seconds. If patient is conscious or when consciousness returns, give emetic (1 table spoon of salt to each glass of warm water and repeat until vomit fluid is clear.) Repeat inhalation of AMYL Nitrate five times at above 15 seconds intervals, use artificial respiration if breathing has stopped! Get immediate Medical Attention!
