Superglue removal |
|---|
| message from Richard Savage on 19 May 2004 |
I have an aluminium tube that has a rubber and nylon plug Superglued
into one end. The tube is about 10mm in diameter and about 500mm long.
I need to remove the plug. I am trying to disolve the Superglue with
Superglue Remover but don't hold out much hope.
Any suggestions?
FYI the tube is a section of a Lecki walking pole and the rubber and
nylon plug is one of the wedges that stopped functioning on holiday and
was glued as a temporary fix that seems all too permanent!
TIA
Richard

Model shops are a good source of several varieties of cyanoacrylate
adhesives, from extra runny to gap filling, so I imagine they would have
removers too. They might have advice as well.

Acetone is a solvent for superglue, and is found in nail varnish remover.
Unfortunately, the missis handed me a bottle of acetone free nailvarnish
remover, and it didn't work too well...

Acetone, or better still nitromethane (try specialist car tuning
places)are the two solvents of choice for debonding CA.

Running a rod through the open end of the tube and tapping the plug
sounds worth a try.
As to Accetone; I think that SWMBO may have some, so I'll try that as
well.. What is nitromethane commonly found in? Sounds not unlike
Nitromors? If that is the case I suspect that it will eat some or all
of the plastic parts of the plug. This won't be a problem if I can buy
a replacement from Lecki - an avenue that I haven't investigated as yet.

Gettinf CA off is a perennial problem for me as an aeromodeller. Acetone
is one of only tow chemicals that relaibly do it. Its available as a
celluuose thinner BUT teh trouble is there are many pther materials used
as such, and they don't work. It HAS to be acetone.
Drag racing cars. Its a fuel additive that has not only a certain
calorific value, but the ability to release a surplus of oxygen. Cars
that can't breathe at high RPM gain huge amounts of horsepower if this
stuff is used as part of a fuel mix. I woudl imagine its available from
some of teh go-fatser shops that actually sell real thuings like racing
cams etc rather thanstripes and aloloy wheels. Try a specialist ar tine
up magazione.
Sounds not unlike
Both acetone and niromethane are powerful solvents. However polythene
and nylon at least are safe in acetone, and nitro. It comes in plastic
bottles.

I'm really not trying to start another thread about spelling, but what
does that mean?

Soup popped his head over the parapet,saw what was going on and said
Try a specialist car tune-up magazine.
Specialist magazines eh eh ?
:o)

sorry: car tune up magazine

Where is the plug in relation to the end of the tube?
If it's heated to maybe 200C, it will degrade the rubber, and perhaps
melt it.
You might also consider drilling it out.
Heating to high temperatures will damage the temper of the aluminium,
and make it less able to withstand bending.
This isn't important if it's at the end of a pole, but if it's in
the middle, it may cause it to crumple.

The plug - more accurately described as an expanding wedge, like the
things in tripod legs - is sealing one end of the tube. I'd rather
salvage the plug for re-use.
How brittle are Superglue bonds? I had wondered about tapping the
outside of the tube around the glued area - a bit like trying to
separate bits of a car exhaust system.

| Ian Stirling replied to Richard Savage on 19 May 2004 |
I'd first try taking a rod a little smaller than the plug, and trying
gently hammering round the edge of the tube, to drive the edges up
a bit, and break the bond.
This may or may not work.
Can you get the other end of the tube open,so you can slide something
down?
Probably not going to work.
The glue is not that brittle, you may break bits of it, but most will
stay bonded, unless you utterly destroy the tube.

Leki replacement plugs are readily available if you need to drill it out.

And thus the problem of Superglue removal disappeared.! Next problem:
suppliers of spare parts for Leki poles!
Thanks Phil

Isn't Superglue water soluble?
Brian

| The Natural Philosopher replied to harry8611 on 20 May 2004 |
No.

| Grunff replied to harry8611 on 19 May 2004 |
Erm, no. No, it isn't.

Some of the really cheap stuff certainly seems to be... ;)
I'm not sure what the formulation of the Wurth branded "Superglue" I
have here is, but that doesn't appear to deteriorate under water - not
yet anyway...

This on one of the very few mentions of Wurth I've seen in this group.
I'm not connected with them except as a customer but they produce really
good quality stuff especially screws which are the best I've seen.
They are supposedly trade only but if you buy enough they don't seem to
mind. Stuff is sold through local reps and delivered next day. You need
to open an account.
Fairly crap online catalogue is here http://www.winzerwurth.co.uk/winzer.nsf

Worked for me when I wanted to remove some. Soaked the thing in water
for a few hours and the glue was pretty easily removed

Wasn't 'Superglue' then. Superglue is cyanoacrylate based. This is not,
under any circumstances water soluble. That's why you can use it to
repair broken teapots.
It's quite possible it was PVA (polyvinyl acetate). Partially
polymerised PVA will dissolve in water.

Superglue is hygroscopic, and degrades over time.

| The Natural Philosopher replied to Bob Smith on 21 May 2004 |
It doesn't degrade that quickly tho. It may absorb water, but it doesn't
dissolve in it - it just goes a little soft and more flexible.
|
| Ian Stirling replied to Grunff on 19 May 2004 |
I think it is water soluble at around 250C, under rather a lot of
pressure.
I'm sure I heard about this as a means of removing CA, but can't remember
the context.

Ok, that's fair enough, but so is steel!
