What kind of glue for plexiglass?

[NSURIT]

I have an archival print washer that has a tiny leak.  It took twenty  four
hours for 1/3 of the water to leak out and ultimately it will sit in a  sink,
so the leak won't matter.  This kind of thing makes me crazy, so I  want to
stop the leak.  What suggestions on products available in the USA  could be used
to potentially stop a leak where two pieces of plexiglass are  joined. It
would be nice if when the glue was applied the resulting patch  was not butt ugly.
 THIA,  <[B^)  Bill  Barber

Bill,
I thought only duct tape or epoxy was permissable for photographic equipment

Just a suggestion as I have not tried patching a leak myself but would
probably try some kind of silcone aquarium sealer. John

Bill,
I would second the suggestion for aquarium silicone.  I have a film washer
(Plexiglas), which also had a small leak.  Applying a small bead on the
inside, has kept it water tight for the last two years.

Just saw this commercial on tv !

Surely, it will fix a small dribble from a water tank ?

Epoxy putty?

I have never worked with plexi but someone told me that each manufacturer
has his own plexi formula and thus his own special glue.  That guy also told
me that silicone will not adhere well enough to plexi - I was thinking about
making myself a plexi aquarium instead of glass.  But for your purpose it
may well work using silicone, as you just need to fill that crack.

Bill,

Most cities have a plastic supply houseor two, and Huston's big enough that there must be several, in the yellow pages. They would have the answer.

All in all, I think the silicone is a good idea. Probably available in small tubes from a pet store.

Bill,
     TAP plastics with outlets in CA, is a great source for stuff like that:
http://www.tapplastics.com/shop/product.php?pid=130&
If you live in CA the store staff are quite knowledgeable, because they fabricate plexiglass signs
all the time in house.

Since you want to run adhesive into a seam, you need the low viscosity adhesive as shown in link
above.    You could also just use Ether, if you can lay your hand on some.

The tube adhesives for plexiglass tend to be higher viscosity so less likely to wick inside. (eg
tube applied:  http://www.tapplastics.com/shop/product.php?pid=132&)

As others pointed out, RTV silicon will also work well as a seal, if placed on inside.
Many RTV's produce Acetic acid while curing, so you need to allow it to clear out by diffusion and
maybe washing before you use it, as it acts like stop bath residue!

Best I can tell with a look around, many silicones should be compatible.? No first hand except with a glass aquarium many moons ago.

I've built two underwater macro boxes out of plexiglass, and two
artificial streams, and when I bought the plexiglass, I also got a
squeeze bottle of some organic solvent.  The squeeze bottle had a large
hypodermic needle on it, and one simple held the two pieces of
plexiglass together, gently squeezed some of this organic solvent
between the two surfaces in contact, and the solvent welded the
plexiglass pieces together.  Sorry, there's no label on the squeeze
bottle, so I don't know what the solvent is.  If the mating surfaces of
plexiglass are smooth and clamped together, they become one solid welded
piece.  I watched the pros in the shop putting together pretty complex
plexiglass assemblies, and it was all done with this solvent weld.  Talk
to your plexiglass dealer.

Bill,
Then you might try http://www.rplastics.com/plastic-glue.html or
http://www.eplastics.com/Plastic/Adhesives
It won't look as professional as duct tape though...

The correct glue for plexiglass is a rather nasty solvent (various  
names) which is a thin clear fluid that melts the faces and allows a  
very strong weld style joint. However it is not a good gap filler so  
a decent caulking compound shoud do the job - a slow cure wet area  
silicone is good so long as the area is cleaned, absolutely dry and  
keyed with a solvent first. Not sure what would etch plexiglass - I'd  
try methylated spirits (denatured alcohol), mineral turpentine (oil  
paint thinner) and acetone as possibles. If you don't etch, black  
mould can creep under the sealant.

My vote would go for    IPS Weld-On 3  

I have edge cemented 1mm thick acrylic &  fixed innumerable plastic toys
with this stuff...

TAP Plastics carry this also...

Not so much of a grammatical correction (I'm just as guilty of those
mistakes as anyone else), more of a technical correction.

I remember my GCSE Technology teacher berating me for describing the
process with the solvent as "melting".  Melting involves heat.  What the
solvent is doing is, as the word "solvent" implies, dissolving.

End result is the same though, and it's the way I'd go.  Use the solvent
to stick it together (should add strength to the crack / break and
hopefully stop it spreading), then maybe use some silicon to fill the
gap if there is still a gap ?

Hope that helps,

Jon
