Heat seal flex sounds interesting, but I do not see any places that sell it.
I did find a place that sells hot melt powder, but none of their distributors seem to sell it. The site is
http://www.lancergroup.com/lancer/ink_catalog/additives_bases/catalog5b.htmlIt is the H-10 powder. I have sent them email to find out who carries it.
I may buy some and experiment, in spite of my earlier comment.
I figure if you can mix this with some copper powder of a comparable size and stick it to some kind of temporary adhesive backer(like tape), then you may be able to accomplish the same thing that 3M does, but wants to charge several hundred for.
