Seeking protective coatings for polypropylene tanks

I am in need of a protective coating that that will prevent gold from immersion plating the walls of a polypropylene tank.

Thanks

I find it hard to believe that gold is plating by immersion on a polypropylene surface. Are you operating an electrolytic gold bath, an electroless gold bath, or a gold bath designed for immersion plating?

Terry, As Ted said, you have to describe your process more accurately. I know zilch about plating, but a little bit about plastics and there sure ain't no coating in this world to do what you want.

PP like Pe has a surface that does not lend itself to things 'adhering' or plating to. If you want to be exotic, go and get a tank made from Halar, Tefzel or TFE which would cost you an arm and a leg. Maybe your process could cause gold to 'deposit' even on these fluorocarbons.

Anyhow, your tank material sounds OK. 'tis something else that stinks in the State of Denmark, eh?
