Paper backed 6 micron Aluminium foil

Hi,

Not sure if this is the right thread to post in. I'm on the hunt for 6 micron Aluminium foil (or thinner) with a paper backing that can be removed using water. I intend to use a cutter to make a trace and then glue that to some mylar.

Any help would be very much appreciated.

I've used thin mylar that has been coated with aluminum through a sputtering process, it is used as an infrared reflector in cryogenic multilayer insulation.

The problem with the thin aluminum is that should moisture get into the system (normally vacuum), the aluminum will very quickly go away, turn to powder leaving only the mylar. So using a wet process to remove the paper might not be the best approach.

I also use transfer tape, 3M type VHB. It comes on a roll, and it is only the glue, no film..so basically scotch tape without the tape. I use it as a bond between two things instead of a glue. It is actually what auto manufacturers use to bond things together in a car, so it holds up really well. It also has a temperature cure cycle, although I do not recall it.

If you transfer tape a thin foil, then slice it, all you do is peel the tape from the sliced part, plant it into place, and burnish it.

The stuff I use is about .001 inch thick, but I believe it comes in various styles.

BAH...note to self...when you turn the Keurig on, always place the coffee cup in the darn thing before you go over to the laptop and write a post...sigh

Hey,

Thanks for the reply. Ideally I would just get some very thin mylar (0.5-3 micron) sputtered with 0.5 micron aluminium but it's difficult to find anyone who will sputter that thick, although I have potentially one supplier who claims they can once they have some equipment set up.

I might have to try the 3m transfer tape, most others I have tried don't work for my use case, although 0.001 inch thick is probably quite heavy.
