Tell me more about Pyrophosphate copper plating


(1998)

I would like to contact someone who uses pyrophosphate copper process on regular basis. I'm particularly interested in Enthone-OMI's "CUPRAL" and Canning's "SUPER PYROBRITE" because only these two companies offers that technology on my domestic market.

Thank you

Dear Adam

For a critical job it was necessary to use copper pyrophosphate and no supplier offered that in India. So I formulated the bath from off shelf chemicals, and converting ortho phosphate to pyro phosphate. If you want to go to those root levels, I can digup my notes.
