Perspex adhesive
 

I'm trying to purchase a small quantity of acrylic cement to bond a
small acrylic tube to some rod.
In the past I've used Chloroform but I don't suppose I can get any of
that this day and age.
Any ideas?

You should be able to get some suitable adhesive from your local sign shop.

Ask your local pharmacist for help. They may be able to get you a small
bottle. You do have to sign a legal document for it now-a-days, though, to
prevent you from using such chemicals in an illegal manner. But you should
be able to get it from the friendly chemists shop.

There's a model shop near me (Stoneleigh, Surrey) which sells small
bottles of plastic weld fluid, which sticks many types including
Perspex. You position the two bits you want to join together, and
apply this very thin liquid to the join so that it wicks into the gap.
It works well, and presumably is available in other parts of the
country. It says it contains Methyl Chloride. I didn't have to sign
anything.

ha, no. Its diy makable but I dont remember how. And not a great
choice. Can you really not find acetone?

Needing to solve a similar problem myself, I attempted to obtain some.
The chemists do not seem to stock it all and would have to get it in
specially and it is not available without prescription.

So I then looked for a alternatives and found http://bondrite.co.uk/

To weld acrylic (which is also Perspex) they recommend WC102 which is
£5 delivered, for a 20gm bottle including applicator.

Thanks for that, have ordered some.

AFAIA, Acetone is not a solvent for Methyl Methacrylate (perspex,
acrylic, plexiglas, etc)

I have found Cyanoacrylate works well with perspex.
It appears to solvent weld it, as well as polymerising.
With care, you can bond two transparent pieces together
with the bond being invisible when you look through it,
and if you pull it apart, the perspex breaks before the
bond separates.

No, I don't think it is.


Not sure that methyl chloride is either, or methyly ethyl ketone..or
Xylene..

These all work with ABS, styrene and PVC though. I THINK.

Acetone dissolves super glue..one of the few things that does.

I was amazed at your claim. I haven't any superglue in the house, but
do have a bottle of Loctite SuperGlue3 remover dated 1994. I tried
this and it worked as you describe after an hour or so!

I guess the SuperGlue3 remover is just acetone.
As perspex dissolves in acetone, this is probably
simply a solvent weld you are producing.

Cyanoacrylate polymerises into an acrylic resin,
not dissimilar to perspex, so the mechanism
of the bond is different with Cyanoacrylate.
(Having read up some more, I suspect I was wrong
about Cyanoacrylate solvent welding perspex, as
it's not in a solvent. It forms a similar acrylic
polymer to perspex, and most likely is that the
polymer directly bonds to the perspex polymer
surface.)
