The question of approval of the adhesive is a good one. I've wondered about that too. When we use typical transformer tapes like the ubiquitous 3M#56, the adhesive is largely used only temporarily, since the next layer or winding will hold it in place. Even for the outerwrap you could argue that the adhesive is backed up by a second means, albeit varnish, so two things would have to fail for the tape to unwind.
BUT...suppose we want to use that same tape on a piece of sheet metal where a live part is too close and fails clearance. We are relying on the adhesive for a safety function. The tape has the UR mark but has the adhesive been tested for long-term adhesion? Is there any way to know without asking the manufacturer for a look at the Conditions of Acceptability in the UL report? Jim Eichner, P.Eng.

The tape should be at least 1 inch wide. If anyone knows of a North-American-located manufacturer/source for such an item, I would greatly appreciate hearing from them. Thanks in Advance.
