If the purpose of the gold film is to reflect light through the tube, I may have a better solution for you. We sell a gold film that already has an adhesive that will apply easily to the tube and give a good bright reflective finish against the glass surface.

Ed. note: Let's not go too far afield, folks, until Mr. Barhate gets back to us with a bit more detail. For example, we don't know if he wants the gold on the inside surface or outside surface; we don't know why it must be a minimum of 10 microns, or how pure or what alloy it needs to be. We don't know whether this tube is the size of a hypodermic needle or an atomic accelerator.

If you are looking to reflect UV/IR than most any metal will do the job, not just gold. Most of those metals will do a wonderful job with only 1 micron instead of 10. Is there any other reason for choosing gold? Any reason for the thickness?

HI,

I tried coating a glass surface in my lab using sputter coater but the problem is,it gets off even by the touch of a finger.So I would like to know if there are any more ways to coat a glass hard with gold and also a few confirmation tests which can prove the strength of the gold coated on to the glass surface
