non-stock coating? need suggestions

[Aubryann]

hello everyone. I did a search but did not find anything related to what I'm looking for help on. I need a help finding a non-stick coating for 99.99% Indium foil that will meet these specifications.

Non stick barrier on one side of material must not stick to copper, aluminum, or nickel plated copper. Barrier must cleanly release with maximum of 100 PSI Axial pull pressure and must be easily cleanable from remaining surface after aging at 600 degrees for 500 hours under 150 PSI applied load.

Any help is much appreciated...thanks,Aubry

A PTFE-based coating would be a good start:

thanks Cory...that's what I was researching but I think the coating would be almost as thick as the material, .010.

Reynold's Wrap has a non-stick coating on aluminium foil:

Here is a patent covering the technology:

thanks again... I think I'm going to go with a thin plastic coating from 3M.
