You may have found that cyanoacrylate glues (superglue) don't 'go off' on some plastics.

There's a darkly guarded secret called Loctite 770.
This is an activating primer intended to allow bonding of even the most diffficult plastic materials with a series of Loctite products but works just as well with Supermarket Superglue.

Use the most microscopic amount, thick coats reduce the bond strength.

Except in the most difficult cases applying to one side only will initiate polymerisation.

 

You can also purchase superglue activator under a variety of brands at most hobby shops...at least here in the states.

 

You guys are just so lucky. No such thing in Europe.
Our local car accessory shop had one can of carburettor cleaner (no brake cleaner) in stock - €17.......

 

Steveinfrance, brew up some Carbon Tet, surely you have a decent supply of chloroform and chlorine, not to mention methane.

Just keep the temp down or we'll have to come and rescue you from the phosgene. If you start to smell fresh cut grass, run away! or don your business suit.

 

Rich,
I've got more carbon tet than we could ever drink BUT it ain't anything like 770.

 

Thought carbon tet was in very limited supply these days.

 

It has been withdrawn from general sale but it has its uses.
