Summary for enthone n-190 Discussion
Using enthone n-190, the original question asked whether one shop could use the same N-190 bath for both nickel sulfamate and electroless nickel (EN). Durmeyer Plating of Atlanta simply asked whether it can be done. Ted Mooney replied that he did not know what N-190 was, but noted that electrolytic nickel plating can be done from electroless nickel baths when nickel phosphate properties are desired; he said he was not aware of the reverse being done. He also emphasized that the practical application matters more than a laboratory curiosity and asked the poster to explain the intended use. A later reply suggested the most direct route: ask Enthone. The thread therefore does not confirm that N-190 is suitable for both processes, only that the idea was questioned and no definitive technical approval was given in the discussion.
Q. I was visiting a shop and found that they use N-190 for both Nickel sulfamate and EN. Can it be done?
Thanks

A. Hi, A. I don’t know what N-190 is but I am aware of electrolytic nickel plating being done from electroless nickel baths (when the particular qualities of nickel phosphate are desired), but not the other way round. But I’m sure you are not so much interested in a laboratory curiosity as some practical application, and it is the same for the readers — so please tell us what you are thinking.

Q. Ted,
Thank you for the follow up. I am just curious to know if N-190 (Enthone product) can be used to strip both nickel sulfamate and EN. Something tells me that it will take a lot longer to strip EN using N-190 because of the high Phosphorous contents. Please correct me if I am wrong.
Thanks

A. I’m not familiar with that product, so didn’t realize that you were speaking about a stripper. Already having said I’m not familiar with it, we’ll have to wait ’til someone who has used it answers. Good luck.

A. N-190 will remove EN but there were issues with it and I can’t recall what they were, I want to say shortened bath life. Contact Enthone for details.
