          Q:The min application temp says 20 deg with a min hold temp of 40 degrees. Does this mean I can apply when it?s 20 degrees but it won?t hold until a temp of 40 is achieved? Please clarify.

          Answer This Question

          A:  Do not apply if temp is below 20 degrees and it does not hold well below 40 degree... so basically not good for outside applications.

            New use in a pinch?
            Okay I have used this tape or the likes on many a/c systems and a few other things but this one was for the bottom of a shower door that was so dull not even Alumabright would make shine so I thought, hmm I wonder and ran to store to buy new tape and well the picture is worth a thousand words. It was all still good but I hated the look and now it's bright like it should be

              Great adhesion and a long lasting bond.
              Sting adhesive ensures a permanent bond to your ductwork. I’ve used the fibre duct tape in the past but heat causes it to dry out and peel away but that doesn’t happen with this tape. I have some joints that I covered 5 years ago which are as secure today as they were when the tape was first applied.

              Great tape for HVAC metal seams but found better use for sealing foam board insulation. Very stickey tape and easy to work with. Stops all air infiltration and makes for a well insulated final job.(Picture) Using 2x2's and R-10 Foam this created a 1.5 inch open channel for air to vent roof heat to top ridge vent. Below the Nashua Taped foam will be R-30 fiberglass insulation giving R40, fully ventilated, ceiling.

              Excellent product. This foil tape is easy to use, and unlike other brands I have tried, peels easily from the backing paper, IF you cut it with scissors! When you tear a piece off, it is much more difficult to separate. High strength, completely impervious to light penetration and excellent workability. Used it to secure bubble insulation over my RV windows.

              Works great for a variety of projects. I have primarily used it for sealing insulation around hot water pipe insulation/mini-split drain PVC lines. This stuff is a significant step up from your standard duct tape and will not fall off. It has a low profile and can therefore be handy for sealing the inside seams of ductwork when sealing from the outside is not an option.

                Do Not Buy This Tape
                This is some of the worst tape I've ever tried to use. I tried using it outside (out of the elements,) and it does not stick if the temp is below 40F. adhesive come off the tape onto the topside of the next run. This tape would not even stick to itself. I would not purchase this tape again.

                  I bought this specifically for fixing my car's windshield shade. The shade folds and the fold locations were weakening. Asked for tape built to resist heat. Was given this. Put it on. Seemed strong when I did it, but two days in the heat, and the adhesive got so warm, the tape came up. It even left a streak of adhesive on my windshield. Returned it.
