self amalgamating tape

I don't think this is a new product. This tape was initially aimed at the Land Rover owner about 5 yrs ago, through the LRO Magazine & I bought a couple of rolls then for my LR.

It was marketed as heat-proof, & high-pressure resistant so you could repair hot radiator hoses etc...
Small bubble-packs of about 3m were something like £3 or so.
I bought a couple of packs as emergency repair kit but haven't used any of it yet, so can't offer an opinion.
It's definitely not the same as a standard large roll of 3M SAT though, which I use everyday for sealing microwave antennae connections.

I think it's called LLFA tape, and can be found at www.h-t-s-uk.com at similar prices.

If it's anything like as good as it sounds it'll be the very thing for emergency (and even longer term) use on boats. And it can only be a lot better than the self amalgamating tape that is sold these days, most of which is rubbish - you used to be able to get far better stuff.
 
We don't seem to have a consensus about what this stuff actually is, who makes it, who retails it and what it is called generically (i.e. not the brand name). I'd very much like to order some but I referred my chandler to this thread and he says that there isn't enough information for him to source it. Can anyone give a definitive answer?

My chandler, who is a keen amateur motor mechanic, uses white standard self amalgamating tape for hose repairs. He sent me a link to the manufacturer of the Spanish product that he stocks http://www.mundoceys.com/index.asp?opc=15&Idioma=ES&IDFAMILIA=36&IDGama=3 and the story becomes more convoluted...

The white tape is recommended only for electrical work but the black tape says "Tackceys Stira & sella, sellado hermético de escapes y fugas. Cinta autosoldante, que soluciona de forma instantánea fugas o escapes en cualquier tipo de tubería o conducción, incluso bajo presión o líquidos corrosivos. En sólo 5 minutos se funde consigo mismo ( tecnología autovulcanizante), formando una barrera aislante eléctrica impermeable." This claims that the product works on vacuum and corrosive liquid pipes, and leaks of various types! Yet this product (which I have been using) seems to be ordinary self amalgamating tape and is sold at that price.

Can it be that there is nothing new here at all? Are we saying that plain old self amalgamating tape is good for repairs on diesel, hot water, etc.? If so, great!

<span style="color:red">EDIT - have just watched the GTG video (see link http://www.gtgengineering.com/index.php?id=guides000 and it is clearly NOT ordinary SAT. </span>
 
Like others here I'm a bit puzzled as to what's so special about this "new" stuff.

I remember using Scotch 23 "self-fusing" tape back in the late '70s. We used it to seal 440V three phase connections to be used at depths of up to around 300m. That's waterproof enough for me! The stuff readily available from the chandlers in black or white seems exactly the same.
 
Watch the video in my liink above (which was also posted by someone else). You will see that the product looks quite different in not just apperance, but also composition, to the old fashioned tape.

Sounds like the stuff that was demonstrated enthusiastically to me a couple of weeks ago, by a marine engineer. It sticks like wotsit to itself and can do the same job as self-amalg tape, but has an intriguing property - I was asked to hold 2 fingers side by side, then about 3 turns of tape were put round. I could stretch it slightly, then roll it off - it made a perfect O-ring which I was told is good enough to make a seal or gasket with. Longer lengths can be made into fanbelts!

That demo sounds familiar, I saw it at the ExCel boat show in january, and it was rescue tape:
