Super glue vs this stuff?

#Post
1

Any industrial chemists on here?

I see Mitre10 have a Wonder Glue:
https://www.mitre10.co.nz/shop/loctite-60-second-all-purpose
-glue-20g/p/309075

Any advice on whether this would be superior to bog-standard Super Glue
(at 10x the price . . .) ?
Have tried ordinary Super Glue and it holds together for days or weeks before finally parting company again.

Application: Repair some reading glasses from the trenches of WWI that have snapped exactly in half, on the bridge that joins both lenses.

The issue: Even though he's a careful old fullah, this structural element is stressed when grandad goes to put the glasses on and the surface contact area is only about 6 x 4mm.

OhYeah.

TIA

Years ago there was a glue that I used called Aron Alpha (I think). As an apprentice I used to glue old dial phones back together. Sometimes they would break again but never on the original glue line. So there are some good glues. The Loctite ones I use now seem fairly good so this one may be ok. There is one I’ve seen advertised that is set with a uv light. The advertising looks good.

most superglue is not waterproof. use araldite for that purpose.

I wouldn't use glue at all. Get in touch with SOS Eyewear (Mt Roskill, Auckland) via net or phone and ask their advice. Their work is fantastic, their rates are very reasonable, and I totally recommend them. They use couriers if not local...

loctite is a very good product but if u want to superglue it then selleys or bostic superglue will do as good a job at 1/3 the price in this case. wont be a permanent repair regardless of brand with superglue though.

what materials are you joining, Loctite instant comes in a range of types, for example - 480 toughened, High impact, high peel and shear strength toughened cyanoacrylate adhesive
https://nzsafetyblackwoods.co.nz/en/loctite-480-toughened-in
stant-adhesive-25ml-each--04659257

or 406 = Loctite 406 is an instant adhesive designed especially for the fast bonding of plastics and rubbers. This product offers exceptionally low viscosity. When combined with Loctite primers for cyanoacrylates, it can also be used on difficult-to-bond plastics.

there is a chart on this site for which to use, not had time to read it yet, before edit times out.

My understanding is that glues can only work by means of (a) Air Exclusion or (b) Molecular bonding.
Is this still current science?
Cheers.

p.s. Good to get solid advice on here without the silly idle comments that often appear on the 'boards, adding to global warming:

I have a mild obsession with collecting second hand designer sunnies. SOS are my partners in crime so to speak, and enable me to wear face jewels I could never otherwise indulge in, lol!

They are really good at what they do.

UPDATE:

Tried a glue called B-7000 diamond acrylic found on TM which has an nifty needle-size applicator. Only problem is the glue doesn't friggin' set or hold.
And if left 3/4 full with the cap on for a month or so, no glue can be squeezed out . .

On closer inspection on the front of the tube, we find:

'Is a surprise adhesive force'
'This was a great adhesive'
'Best-selling Europe and America'
'Mad fans around the world'

On the back, more rambling text in tiny 0.3mm high font, that can only be read with a magnifying glass.

Draw your own conclusions.

The tricks for the use of superglue are:
resist the temptation to use too much
it is a glue not a filler.
It sets in the absence of air

I recently purchased from The Warehouse some "super glue type stuff" that sets rock solid on exposure to uv light, (about 5 seconds worth), and can be used as a filler... I have found it works well !! It comes with a little uv torch.
It is one of those "as seen on tv" / "but wait there is more" etc type of products

I can vouch for SOS too and they are really cheap

The cements that dentists use for modern (non amalgam) tooth fillings require UV in setting them, and they're definitely not meant to fail.
