Scotch Rubber Mastic Tape 2228, 1 in x 10 ft, Black, Conformable, Self–Fusing, Electrical Insulating, Moisture Sealing, Indoor and Outdoor Applications, 65 mil thick, 1 Roll

Great for Highlander Hybrid Battery Sealing - Needs Heat! I bought this to seal the frame of my Highlander’s hybrid battery to prevent air leaks, similar to the strong OEM tape. At first, I was disappointed because it didn't seem to stick at all. However, after some research, I learned that this type of tape works best with pressure, stretching, and a bit of heat. I used a hair dryer to warm up both the surface and the tape itself, and then it bonded perfectly. For my specific purpose, it’s a great product. I wanted to share this tip in case anyone else runs into the same issue!

There really is nothing else like this....it's not cheap, but it really works. I tend to use it for bicycle-based applications but for whatever you need, this stuff works. I love how it can stretch and flex but still hold its tension/stickiness when applied. For my uses, one roll lasts me a long time.

Good stuff. But NOT for installation sealing. It's stretchable but not conformable to irregular surfaces! It's only adhesive on one side but it is very aggressive. Once applied it is nearly impossible to remove. Use with caution and forethought! I was using it for the wrong purpose. It is meant to be used as an overlay wrap. Once the two surfaced touch they fuses together instantly.

I had a problem with chain slap on my hard tail mountain bike. The bouncing bike chain was hitting the frame and chipping away the paint. On several occasions the chain bounced right off the sprocket. After doing some researching on chain tensioners and frame protectors, I ran across an article that talked about using this tape to protect the frame. Well, I tried it and it works pretty good. It was easy to install. Just clean the frame, cut a piece to length, and stick it on. I immediately noticed the lack of noise as the bouncing chain now hits this "padded" tape instead of the metal bike frame. Additionally, the tape "absorbs" some of the energy and the chain hasn't bounced off since. Cheap solution to common mountain bike issue.

Excellent product for waterproofing electrical connections. Have used this to waterproof extension cords used outdoors all winter and for coaxial cable connectors. Proper procedure: first wrap connection with good electrical tape, a layer of this product, and a final layer of electrical tape. You will not get any water ingress and the connections will be pristine if you ever need to separate the connections.

I used it to make downtube and chainstay protection on my mountain bike. Works very well, prevents chips and scratches, and looks cool if you line it up right. My only complaint is that it isn’t friction resistant at all. Had some brake housing and wanted to see if the tape could help prevent damage from the rubbing, wore right through the tape. TBH I wasn’t expecting much since it is fairly soft but I wanted to try anyway.

This stuff is amazing. I use it on some of electrical connections especially when putting underground like my landscape lights. It’s very easy to use. Even I can do it!😊

This stuff works, espescially for wrapping and waterproofing underwater hoses and wiring, but it’s expensive. Needs a competitor product.

Got this excellent black tape for mtb frame protection. I highly recommend 2228, was easy to apply. I used one box (£20) and cut strips and fitted side by side. It is maluble to seal together. Covered underside of all the bike frame, to protect against stone chips. Used on down tube and chain stay. Not bothered about weight of tape. Might be a pain to get off, but I will be putting new on.

Used as slapper tape on my chain stay, sticks well and looks good.

I am sure it is used for other things but I bought it for use on my bicycles. Sticks well and is thick (one sided only). 3M/Scotch quality. Much easier to order from Amazon that to hunt for in the stores...
