Formulation of nickel brightener



(-----) 2004

Q. Hi to everyone,

Thank you for the good web site and I want to ask you some question about some kind of substances uses in bright nickel aluminum as aniline pyridine and sodium allyl sulfonate. I want information about it if that is possible

A. Nickel brighteners are probably the principal proprietary product in the plating industry--whose journals, conferences, research, and professional societies were largely made possible by the sale of these proprietary brighteners. Therefore, many people get shivers just reading the words you've written on this page, Mr. Alhamak.

ASM Metal Handbook
9th Edition, Vol. 5

"Surface Cleaning, Finishing & Coating"
from Abe Books
or

(your purchases make finishing.com possible)

You can
• Buy nickel brighteners as a proprietary from the suppliers who offer them, or
• Hire a consultant experienced in it to formulate them for you, or
• Spend decades developing them yourself -- but this will also involve 'synthesis from precursors', sort of like making plastic from crude oil, or
• Instead of modern brighteners you can use older generic brighteners, where good information is freely available in the literature, like the nickel plating chapter of The ASM Metals Handbook Vol. 5.

Best of luck.

A. Ted is right, there is no point in trying to formulate your own brightener system. All over the world these additives are bought from suppliers. This is cheapest way as the supply house gives you also technical support like regular analysis, hull cell tests, advise you with the right preplate process, etc. So please look for a supply house.

I hope that in the near future you will also look for a supplier in our country, as we are so close and yet so far away for the meantime.

Q. Dears,

I am happy to write to you, it's a great site and all of you too!

I want to know what is the chemical formula or chemical components of nickel brightener?

I need your help

Thanks

A. Hello, cousin Mahmoud. An aside first--

You won't learn the formulation of modern proprietary nickel brighteners, but you can get a truly excellent introduction to generic nickel brightener systems, how they are formulated, and how they work from the Metals Handbook, Vol. 5, "Surface Engineering". Good luck.

A. Dear Mahmoud Taher

You ask about chemical formula or chemical components of nickel brightener and you will not receive any answer because the chemical formula for any brightener is top secret know-how for the chemical companies.

Thanks

A. Non proprietary, generic addition agents are available, and the chemical formulas for several, as well as the concepts of brighteners, auxiliary brighteners, carriers, and other addition agents for nickel baths are discussed in rather good detail in Volume 5 of the 9th edition of the ASM Metals Handbook, "Surface Cleaning, Finishing, and Coating". Pretty much the same article is in the current edition of the handbook, in the volume now entitled "Surface Engineering".

35479
(deliberately blurred to illegibility to convey depth of coverage but not violate copyright)

However, proprietary addition agents have been developed to address the various weaknesses in the generic approach. You may be able to get some general info on that by reviewing expired patents.

Naturally, the developers have guarded these improved brightener formulations carefully. Furthermore, these addition agents are often not simple mixtures of readily available chemicals, but rather must be synthesized from precursors. So I don't think that a published textbook describing how to formulate modern proprietary systems exists.

If a "black book" exists, one might well find themself prosecuted for industrial espionage and theft of trade secrets if they are involved with it ... but good luck.

A. Sure it is possible to buy nickel brightener formulations both legally and not. There are people who will sell a formulation, which they legally own or legally have knowledge of, for a price. However, in the long run this would not, if done legally, be less costly than a user buying their own brightener.

Most of the information in the public domain refers to general formulations and others that are outdated. As an example you can find out that, for barrel nickel, cadmium sulfate and/or epsom salts makes a good brightener. The suppliers of many of the organics (both reacted products and precursors) for modern brighteners have tightened up on the dissemination of the information regarding using their products in formulations. How much money are you really going to save?

If you are going into the chemical business, it will cost a lot of money to procure a formulation from legally proper means.

2006 -- this entry appended to this thread by editor in lieu of spawning a duplicative thread

Q. Dear Sir.

We want to purchase nickel brightener-making formula book. How do I get? I am waiting for your reply.

Thanks,

A. Hi, cousin Kenan. Again, if you are speaking of a published textbook or published articles which offer greater detail than can be found in the previously recommended ASM Handbook, people are welcome to name the literature and to help us all find it; but I've expressed my opinion that deep detail doesn't exist in any published books. It goes without saying that we're not going to facilitate industrial espionage through the sale of a black book of trade secrets :-)

Q. Hi.
I have a shop where I sell nickel brighteners. I know the formulation of all brighteners except maintenance brighteners please send me the formulation of maintenance brighteners.

thumbs up sign Hi cousin. We appended your inquiry to a previous thread on the subject and, as you can see, sorry, but it's not likely to happen :-(

Meanwhile there are many people waiting in line in front of you seeking the information which you say you already possess. So please answer their questions first :-)

A. Literature I have [from hobby plating site] says saccharin is used for nickel brightener, 1 tbsp per US gallon of solution.

Randy Maunder
- Lawrencetown, Nova Scotia, Canada
^


October 19, 2012

thumbs up sign Thanks Randy! Yes, the use of saccharin in bright nickel plating is discussed in the previously referenced article in the ASM Handbook, and your 1 tbsp (1/2 ounce) per gallon sounds reasonable. Saccharin is better used when plating steel parts than when plating diecastings, though, because (according to that article) saccharin in the presence of zinc contamination gives dark streaky deposits in low current density areas. The nomenclature is confusing but, for the record, saccharin is actually a "carrier" or "secondary brightener" rather than a brightener.

What can I use as a good maintenance brightener for nickel plating

February 24, 2014

Q. Sir, I have used PA PAP for maintenance brightener. What else can I use for good maintenance brightener?

muhammad abubakar [returning]

A. Hi again, Mr. Abubakar. Things are done a bit differently in my country than in your country, and I don't think we can help you.

Here in the USA, the suppliers of plating processes study and experiment for many years, and acquire a deep trove of proprietary knowledge about how brighteners function. These suppliers pride themselves that no one in the world knows as much about the subject as they do. They don't sell their knowledge in books, but keep that knowledge confidential and sell blended brighteners to plating shops at far higher than their raw material cost, while offering those buyers the free-of-charge technical service & support they require to efficiently use these products to produce highly satisfactory plated components.

The Chinese model is apparently to sell brightener components cheap as commodity chemicals and let the plating shops fare for themselves. It's not that one economic model is good and the other one evil, but that they are not compatible. You just can't ask a Western supplier of plating process chemistry for their knowledge of how to formulate a brightener system, because their business model is to incorporate that knowledge into the product they sell; it's sometimes said that they "sell their know-how by the gallon rather than by the paragraph" :-)
Good luck.

Q. I would be glad if you kindly name the books used for the guidance of development of brightener which I can purchase from international market.

S. Najmul Hasan
- Karachi, Pakistan
^


September 2017

Hi S Najmul. Sorry, but I am very confident that no such book exists on the international market. And unfortunately, if it's not from a recognized publisher or authority, we can't put you in contact with the author because we must be very careful to not abet industrial espionage.

You can start with the ASM Metals Handbook vol. 5, which explains the general principles behind brighteners, carriers, and secondary brighteners, but then you'll still have to spend a lot of time reviewing decades of patents to get a deeper understanding. Simply, the major suppliers have spent decades developing brightener systems and they offer the developed chemical systems rather than books, because there is no way to recoup their investment in development cost from the sale of books.
