The documentation is conflicting. Can this be used to seal joints in rigid metal HVAC ducts?
Asked by David October 19, 20205
AnswersI don't know for sure, but it is a metallic tape so it seems like it should.
Will this tape work too block out interference
Asked by Oleo June 13, 20202
AnswersInteresting question which I doubt anyone has the answer to. In general, I doubt it. Wrapping around some box that holding some sort of circuit board??? Sure it is "interference"?? In general "Interference" can only be tamed with some sort of grounded wire attached to whatever. Doubt this tape would conduct to a ground wire. Perhaps thin aluminum box as shield?? thin aluminum is available at Depot. Some interference is caused by multiple lines running parallel to each other such as Ethernet and 120VAC close together for a long parallel run. Never want to have long runs of anything and an electrical cable such as telephone or thermostat or Ethernet or any other low volts cable. Sorry I could not answer "yes" or "no". Again, I doubt it.......Oh, I am a college EE.

It STICKS only to ITSELF
The sticky part is on the outside of the roll once you pull back the tab... I cut down through half of the roll trying to get to a section that wasn't that way.... I never got anything but the sticky stuff on the wrong side and therefore useless as glue was was on both sides. Apparently, it is a common occurrence based upon other reviews I am reading ...now... too late to do me any good.

I have found no special attributes that would make this an all weather tape. I believe Its adhesive properties fall below the original duct tape and its rip strength is questionable. The construction lacks any strengthening materials such as cloth or scrim. Its not my ideal choice in its class of tapes.

This tape is ok if you use it all within a year or so. I bought it to tape some duct work and it seemed ok but when I needed to use it again a year and a half later, the metal coating came off as I unrolled the tape plus it was no longer sticky. It was never stored in an extreme environment.

Cheap trash that is unusable after spending one season inside my air conditioned house. The roll of tape is stuck to itself and is unable to unravel as you would normally expect.
I will now go out of my way to never buy a Nashua product again.

Awful quality
I purchased two rolls of this tape and both rolls are unusable. I literally took one roll out of its plastic wrapper and the backing peeled right off the tape. The tape actually stuck to itself like it was melted together. I used about three yards off the other roll and just chalked the first one up to a bad roll. Then it started doing the same thing. Out of anger/frustration I must have wasted another 1/4 of the roll trying to get it to work properly. Now I have $25 of worthless tape. I'm ticked to say the least, now I'll have to go buy more of another brand and hope it works.
