Default liquid electric tape?

Anyone here use it and what is its durability? How about melting
temperature in warmer environments? Thanks.

I have used it on connections between coax and antennas. Never had a
problem. Regular PVC black electrical tape either splits or looses it's
sticky after two years due to the UV here in the Central Oregon desert.

Liquid tape in bottles turns solid after about two years.

I bought a can of this stuff at the local hardware sto
https://www.amazon.com/Star-brite-Liquid-Electrical-Tape/dp/B0000AXNOD
My first use was to patch cracks and cuts in several expensive rubber
cables. It went on fairly easily but hardened a bit lumpy. It lasted
about a month before pieces started falling off. There might have
been some contamination (grease, hand oils, solvents) involved, but it
was too late to check. I later used it for rubber microphone coil
cords, which also crumbled after a few weeks of movement. This time,
I gave the cable an acetone wipe, which should have removed any
grease.

However, the lack of durability was not the major problem. It was the
can. No matter how hard I tried, I could not keep the rubber compound
from getting into the threads on the lid. Once the stuff hardened, it
was impossible to remove the lid. I tried various straps, clamps,
pliers, pipe wrenches, and solvents. Nothing would get the lid loose.
After losing the contents of 2 cans in this manner, I gave up and
decided to find something else.

No clue on melting temperature.

¬*I used liquid Tape to repair a large nick in the insulation of a heavy
duty extension cord over 25 years ago.

¬*The cord is still great (but very heavy) the repair is fine and I
never thought about it melting, but I'm in Florida and I never noticed
it soften.

Wish I could till you the brand and if they still make it the same way.

I used some liquid electric tape about five year ago. It was to
insulate a joint in a cable supplying the pump in a waterfall. It is a
few inches under a lawn. It gets frozen in winter and baked in summer.
I think it is Loctite brand.

Unless you have some special requirement I would advice self-amalgamating
tape instead.

I'm a regular with liquid nails when wiring up construction sites and I know the feeling trying to recover goop, sparkle, other tube/can/bottle contents. I guess ultimately two channel locks going in opposite directions might crush or damage the bottle if wet rags don't cushion the jaws. I've seen where you could use a belt to unscrew an oil filter near a car's engine for an oil change.

My experience is similar.

I tried it once. Was not impressed, seemed to crack off after a while.
What I have used that I really like is rubber electrical tape. Ethylene propylene and silicone rubber electrical tapes have the highest dielectric rating of electrical tapes, as much at 70KV. I use 3M 2228.
I learned about this stuff during my first engineering job in a blast furnace construction site. the controls I designed interfaced to some beefy motors. One of the electricians that followed me around was tasked to replace one of the motors because it was not what I specified. As I watched him wire the new motor, he used that rubber electrical tape. Neat stuff-the overlapping wraps fuse together to make a rubber jacket. Long lasting in hot and cold environments. Follow up with a few wraps of good electrical tape - I like 3M 88 or for everyday use, super 33.
Good luck
J

It costs about $1/ft:

I've used it on radio towers and found a problem. The self-fusing
glue is so tenacious, that removing it from a connector is almost
impossible. For situations where you're certain it never needs to be
removed, it's great and quite waterproof. For RF connectors that need
to be removed, I use 1" wide PTFE (Teflon) tape for waterproofing,
covered with 1 or 2 layers of Scotch 66 to hold it in place. When the
tape wrap is removed, the connectors look like new.

There is a product called Sugru, it's not liquid but rather a very resilient rubber putty. Cures in a few hours, It's mold-able and comes in several colors. I've used it to repair things and reinforce cords where they exit devices. Handy stuff.

Yes, good point - it is rather tenacious. If the connection needs to be reworked in the future, it is a little tough to remove it. I've tried teflon tape on occasion and found that it slides and shifts around so much that it is hard to get a clean wrap so to speak. One good thing is that teflon tape has a very high dielectric strength, something like 6kv at 0.001 inch thick, (or is it 0.001? i forget). It would do quite well in RF applications.

Late on this, but there is a material called Bond-Tech GS 112 rated for electronics and cables. It is also food-safe and stable (solid) to 85C +/- 5C. This stuff is NOT meant to be re-worked, nor would I think that any liquid-applied material would work well that way. It would have to dry out in a way that does not adhere to the substrate to be easily removable. Which seems contrary to the intent, unless very temporary.

Just a thought.

In WWII, the japanese used something called the type 95 by Tokyu Kurogane Industries and I guess you could remember the Volkswagen K√ľbelwagen (type 82) from Hogan's Heroes.
