Copper tape with strong adhesive

[Bricksnbeatles]

Anyone know of a copper tape that has a permanent/industrial-strength adhesive backing? Conductive adhesive not at all necessary. All of the copper shielding tape I’ve used over the years has had a pretty low tack adhesive that’s fine for its purpose but loses adhesion very easily with minimal effort.

I have some… “ideas”, for some things where bonding copper tape to external surfaces would be necessary.

Legit, re; not $4 on Amazon, shielding tape has a super strong adhesive. So much so that it typically has to me removed in pieces. I'd say buy some from an actual shielding company/supplier. And make sure it's applied to a clean surface.

Do you need copper because you want to solder to it afterwards? I ask because aluminum tape provides equal conductivity and shielding provided that you don't need to solder to it, and aluminum duct tape (for heating / air conditioning ducts) will stick forever.

If you need good copper tape, you could try McMaster-Carr (https://www.mcmaster.com/products/tape/conductive-copper-foil-electrical-tape/).

Also, Electronic Goldmine has some copper tape, although I don't know how good the adhesive is - this one is presently on sale https://theelectronicgoldmine.com/products/g25118

One quick addition - that HVAC aluminum tape is great stuff, but be extra CAREFUL regarding the edges of the tape - they can be sharp as sh*t, and can give you a wicked cut. I usually wear work gloves when working w/ it, which also make it easier to press the stuff down for optimal adhesion.
