This tape is NOT sticky, really, it's not meant to be. The tape works by fusion. Within seconds, the tape will fuse to itself. This tape has great use in taping around objects, rather than other usages of like duct tape or scotch tape. Figure this, i just soldered an 8 gauge wire to another 8 gauge. Now, I use the F4 tape to tape it up (and insulates it).How you can do it is:Hold on end and wrap around the wire until it comes back to the beginning. Pinch that for 2 seconds to secure it. Now with the extra, unfused, tape. Pull tight and wrap around the exposed wire until completely covered. If not enough was cut, cut more, press the new tape onto tape on the wire (it fuses) and continue. I use this strictly for electronics, but i'm sure it has other uses.

Does this tape meet mil-i-46852 type ii

Our F4 Tape significantly exceeds the specifications as described in CID A-A-59163 (which superceedes MIL-I-46862).

What's the maximum temp this tape will take?

F4 Tape resists 500F degrees (260C).

Can this seal a small split in a superconducting super collider?

The Superconducting Super Collider proposed by the University of Texas Austin was cancelled in 1993 due to budget problems. With that being said, if you are talking about another Collider of similar ilk, and the split was less than and inch wide, the answer would be a resounding “probably not.” I hope this helps, and have a great day.
