Frederick Gumm Solution
I am looking for a formal method for a Frederick Gumm product and any literature available on the subject. The solution is Clepo Pk (II). It is used as an alternative to coating with chromium (VI) with a lower content of chromium. I think the solution may be based on Chromium (III).
Any information would be greatly appreciated.Cora Devoy

I suggest contacting MacDermid or Dipsol. One or both of these companies should have the answer to your question.

It's sold in the UK by MacDermid under the name Tripass PK3 and is as you suggest based on Chromium(III).Dougie Lightfoot
