Questions & Answers

The adhesive tape comes with a removable protective backing that needs to be removed in order to apply ?

Using a ragged edge, you can better separate the backing and the tape if you tear the backing instead of cutting it.

What is this painted to look like? Is this aluminum or is it painted to look like foil? My cat chews on cords so I need some aluminum tape to deter her from doing so. ?

Aluminium is what it is. My use of it in my art is great. It's plumber's tape used for ducts, although I bought it for my art. If it works for your cat, then that is great. It took me less than $10 on Groupon to get a set of flat braided rope covered charging cords for my cat to stop chewing. It was the best purchase that I have ever made. It might be a good idea to look for something The appearance of this will be much better than The Amazon Prime set is $99 and comes with 5 pairs).

What is the construction of this tape? Is it lined, ?

It's really hard for me to understand what you're asking, but I'll do my best. I don't see any straight lines that I could use for straight cutting or for measuring. Unless you are asking about maybe a plastic lined coating, then I would call the top unlined, otherwise called lining. There are only two of them. Approximately 7 mm thick aluminum foil with a shiny surface on the front and a sticky surface Crinkle this stuff, and you will get creases like you'd get with aluminum foil, but it will also form to the thing you're sticking it Tape like this can be used to wrap foil insulation around ducting or to tape reflective materials, such as Panda film, together.

This tape is designed for patching mufflers, but will it work on ?

There isn't quite a heavy gauge tape here. Kim thinks they make a more heavy duty foil tape that can be used to repair mufflers cheaply. The thickness is unknown to me, but he thinks it would be good for a quick fix. People who have done it have come to my attention.

It's a false advertisement that it's The distance is 7 miles, but the number is A 1 mil thick piece of paper
3/5

The tape that I received today was too thin to be 2 inches wide, and it looked like a tape from another life. The measurement was performed with a high precision micrometer and I got a reading of 1. 25mils. There are 1 mils in a mil. There is no mention of 1 on the 3M site or even in the product description. The size of the attachment is 4mils (See attached This is NOT the thickest part of the sandwich. There wasn't a 7 million ad as stated, so it was As a result, I paid same day delivery since I needed it so This is so disappointing for me.

It was recommended by someone else as easy to remove the backing of this tape
5/5

In a nutshell It was recommended by someone else as easy to remove the backing of this tape. This backing is a bit difficult to remove. As for the tape itself, it's a foil tape. Other than the thick insulating stuff, they're all pretty much the same. Although I've used tapes that were easier to remove, I've also used other tapes with better abrasive properties. The following changes have been made since April In order to upgrade to 5 stars, I went through the roll and learned that I was responsible for the problems removing the backing. If you tear pieces off, it is difficult to get the backing off without tearing them The process of cutting it out is easy if you have a clean edge. You just need to curl up a corner with the foil facing There is no foil tape left, and because the backing flattens out a bit, the tape kind of peels right off.

You rock, Shiny! It was purchased for an insulated garage door I had installed a few years ago with foil coated foam board
5/5

Originally, I used some cheap foil tape from no name brand that worked great, but it had started to peel in some places. My patching up of that damaged area with some quality 3M cold weather foil tape went very well. There are however a million little 3M logos on that 3M foil tape. It made me feel nauseous just to look at it. This tape is for you to enter! Now I just left the little 3M logos off and I'm left with a shiny background and a penguin wearing a hat (brand name logo on the foam board I This is a very big improvement! I have found this stuff to stick pretty well, and it is pretty easy to use. There are only two problems First, there is the paper backing which is a pain to peel up depending on how clean you tear it. The solution turned out to be to work the paper on the back of the tape as I was rolling it out to avoid the frustration.

This app is great for art journaling! The above can be used as a metallic surface for embellishments or as an art journaling medium
5/5

Not your usual use for this! As a tape, it is thin enough to mold around the contours of embellishments, yet thick enough to withstand some heavy-duty The backing can stick to itself when you peel it off, so be careful when you do it. My Sizzix machine drew the paper through the metal dies from AliExpress when it was taped to copy paper. The cuts are generally excellent, but at times, they are less accurate on cardstock. Test your AliExpress dies, as they are not always as sharp as Tim Holtz's, so run a test. I do not take off the backing of the die cuts before adhering them down, as the metal tape is not strong enough to resist removal of the backing.

The material is tough, thick, and is perfect for use on ducts and vents
5/5

I used this on a furnace/air conditioning blower in a stairwell where, since we already had thin aluminum file tape applied to various connections to ducts and on joints between components like a whole-house Usually the tape came off, but sometimes it was reapplied When was the last time you performed two math operations I have been doing this for four This is a great improvement from when I ordered and did not realize how much ticker I would get. The adhesive should hold up well with this so I don't expect to see any air leaks anytime soon. I'm hoping it will have a much longer shelf life than the previous brands I had used. ".

The paper on the back is too thin, and removing it is a There is a lot of value in the brand name of 3M products, but the quality There is a high price for this tape in comparison to other products, but the It takes quite some time for me to remove the tape from the backing paper every time, and it often causes frustration
3/5

It is very hard to remove it, especially on the job site, and it is too thin for the material to stay firmly in place. the adhesion is excellent, this product sacrificed other factors that made it effective. The whole thing was a waste of money in my opinion.

The outcome was better than I had hoped for
4/5

This is a roll of sealant that was purchased to seal ductwork in HVAC systems. I chose it for its good value, especially since it came in a big roll. I have been using it for a month and it seems to adhere well. If the air ducts carry heat instead of AC air, you will know it during the winter. However, I have a slight concern since this is not listed as UL certified, so maybe I should have spent a few more bucks for the thicker sku, which I also did not like since it had "3M" printed all over it.

There are some good products made by 3M
5/5

The tape served as a sealant for edges. There are some good products made by 3M. As a sealant for some foam heat shielding in the engine compartment of my van, I used this tape. The aluminum foil is quite thin but strong and is well trimmed around the heat shield. You need to be careful since this tape has a strong adhesive, so you don't want it to stick to itself after you remove the paper backing. With some trial and error, I peeled off a small portion of paper and taped it. Then I slowly pulled the paper away while putting the tape down. Additionally, here are some things to consider In order to separate the foil from the paper, I used a bit of masking tape - one piece on the corner of the foil, the other on the corner of the paper. I'm happy with the result. It is recommended.
