Want to market PPS and PPS-OH for nickel brighteners


(1996)

Q. I am looking for a directory or list of nickel brightener manufacturers in the US, specifically using PPS and/or PPS-OH in their formulations. Wonder if anybody could help me out in finding the above or give me any clue. Thanks.

A. Hi, Elena. That's a tough one because proprietary brighteners are a principal income source for most suppliers, and I think they will be reluctant to give much information about what components they use in making them. However, you might talk to the suppliers of nickel plating solutions that you can reach, and see what you find out.

Look under "Plating Processes, Nickel" in the "Products Finishing" Directory (ISSN-0032-9940/82), for a list of about 50 suppliers.

P.S. -- What exactly is PPS?

Q. Ted,
Thank you so much for your help.

PPS is a chemical used in the manufacture of nickel brighteners (propanesultone). PPS-OH has the same application but being of different chemical nature (Hydroxysulfopropyl pyridinium betaine) is less hazardous. I'd need a further little help from you, how can I get to the Products Finishing Directory you mentioned? Is this something I can access to from Italy on the net or finishing.com? Thanks again.

A. The Products Finishing Directory is a handbook published annually by Gardner Publications. It is inexpensive, about $10 or so. A library or bookstore should be able to provide availability info from the ISSN number I gave you. You may find copies of old editions from on-line bookstores, or contact Gardner Publications through pfonline.com

A. Try Enthone-Omi in Italy or anywhere else in Europe. They manufacture nickel brightener.

A. Hi Elena,

I have been watching this letter since it was first posted. I don't know what you do in Italy, but talking about brightener formulations openly in the USA is an absolute taboo. I mean, it took me years to say saccharin (gasp) in public (I still blush when I do that). I wasn't going to be the first, but since you told us what PPS is, I guess I could talk a little bit about nickel brighteners. There will probably be a cross-burning on my front pebbles tonight, but here goes:

I believe that propane sultone is a precursor in a pathway to the pyridinium compound you referred to in your last letter. But this has more to do with designing nickel brighteners than it does with formulating a practical nickel brightener. Many companies sell organics which function as Class I or Class II nickel brighteners and can be mixed right up in your sink. That's always been a fantasy for platers in these parts; buy the commodity chemicals for 1/100 the cost of buying proprietary additives from chemical houses.

I no longer work in formulating brighteners, do you sell organic chemicals? I'm still not sure what you can do with this information, not that it's any of my business.

Best Regards,

Wait 'til you see the ads in Metal Finishing magazine, Tom! There, right out in the open no less, a company called Seal Sands Chemicals is offering "A finer finish for nickel plating", PPS-OH-40% w/v. They go on to say this is 1-(2-Hydroxy-3-sulfopropyl)-pyridinium betaine, that it's pyridine-free, and that they also offer N-benzylniacin 24-26% w/v as well.

As you can see, Bert, we appended your inquiry to a thread wherein at least organizations seem able to offer you such technology, and seem eager to do so. Good luck.
