Cyanide copper brighteners
2003
Hello...
I am a new electroplater. Also I am a chemist. So I need some information about cyanide copper brighteners. What do I use(which chemicals) for more bright plating ? Please, don't say me: "choose what do you want". I LOOK FORWARD YOUR ANSWERS.
Sincerely...

Past history of brightening cyanide copper deposits includes the use of tartrates (Rochelle Salts) as well as the additions of selenium and arsenic compounds. There are also a variety of proprietary materials available that use organic compounds or a combination of metallic and organic compounds

Hi, Alaattin. Safranek's "The Properties of Electrodeposited Metals and Alloys".
recognizes not only Rochelle Salts, but a proprietary selenium-based material which acts as a brightener when applied with periodic reverse current. It does not recognize any other brighteners for cyanide copper baths.
