Strongest glue available on general sale...What's the daddy?

[Wacky Racer]

As per thread title.

I'm not just talking about normal "superglue" that you can buy in any d-I-y shop........

[The Nur]

Araldite is pretty good for readily available stuff, I imagine there is stronger though.

Depends on what it's for, no one glue for all jobs. It's a bit like saying what is the best car in the World....

[Granfondo]

Sticks like st is very good for lots of jobs!

[Gorilla Boy]

Sikaflex is awesome stuff, Q bond isnt bad either for smaller stuff.

[Zyp]

Gorilla glue.

[anonymous-user]

epoxy glues are usually best

I've been using: http://www.amazon.co.uk/Q-Bond-QB2-Strong-Adhesive... today.
Awesome stuff

But the clear adhesive does seem to thicken and stop working a few months after opening

is a good answer, sticks most things and ridiculously strong, gap filling with the foam action, too.

Depends what you want to stick together.

If skin then cyano acrylate (super glue)

Let us know

Thanks for the replies so far...

Don't have anything particular in mind, probably metal to metal, I have seen Gorilla glue in shops and it seems to be pretty good stuff going off some reviews...

I was at a trade show once, and on one of the stands a guy stuck two pieces of thin rubber tubing together with one tiny drop of glue, and five seconds later the assembled crowd couldn't pull it apart, no matter how har they tried...it was almost unbelievable....

super glue is good for instant bond of rubber, but its not flexible.

the normal way of "sticking" metal together is to weld it - however there are many car parts now which are metal to metal and are bonded - normally with aerospace grade adhesives.

As others have said, it depends what's being glued. Many years ago I wanted to glue perspex to aluminium and went to a local bearing stockist who had a loctite 'glues chart' where on each axis was a substrate, go along both axis and find the glue where they join (if that makes sense). Anyway he sold me a 2 pack, just a bead on one and a couple of drops on the other, clamp together and 1/2 hour later a good bond. Fast forward 5 years and I tried to get them apart, the aluminium bent, the perspex broke - but the glue didn't!!
There's some great product out there, 1 of my favourites is Stixall from Toolstation (a PU adhesive like sikaflex but only £7 a tube)

That stuff is Power Bond n fleabay for around £10 for 3 small tubes. Doesn't work on everything but is pretty awesome. Works on exclusion of oxygen when you push 2 surfaces together. Keep it in fridge.

As hman said, metal to metal - weld, braze or solder.

There are three types of adhesive bond failure:-

1. Failure of the adherends (the bits you are sticking together) themselves. Imagine sticking foam rubber with araldite, the foam would tear first
2. Failure of the bond between the glue and the adherends
3.

Giss a chance - bloody internet

As hman said, metal to metal - weld, braze or solder.

There are three types of adhesive bond failure:-

1. Failure of the adherends (the bits you are sticking together) themselves. Imagine sticking foam rubber with araldite, the foam would tear first
2. Failure of the bond between the glue and the adherends- the glue peels off one surface
3. Failure of the glue itself

For a good bond, the adhesive should stick well to each surface, be coated in an extremely thin layer, strong physically and not degrade over the lifetime of the joint

Typical choices include:

Epoxies are generally good, but make sure they are mixed well and keep the glue layer thin (reduces No.3)
Cyanoacrylates are good for No.2 but weaken if exposed to water, particularly warm water
Polyureathanes are good when exposed to water, but not particularly strong - see No.3. That's why the windscreen guy can remove your old windscreen with a razor blade

I saw exactly the same demonstration at a show and as a result, I bought some, as did my mate. It was utterly crap, we tried on so many different items but the only thing we could find that it would stick to was freshly cut, super smooth rubber.
Nothing else.

At the other end of the scale, this reminds me of an old Viz Top Tip:

"Makers of 'No More Nails'! I think the phrase you are looking for is 'A few nails wouldn't go amiss'

[tricky1962]

Probably No.2 failure then

Nice clean, fresh surfaces give the best adhesion for glue. Any contamination from grease, dust or moisture messes adhesion up big time
