Super Glue mini-bottle that doesn't harden by itself while stored capped?

<< < (7/11) > >>

Cecil:
Two superglue tips that perhaps everyone does not already know:  There are activators sold that substantially decrease the cure time.  You can apply it to the workpiece before the glue or spray it over top of the glue.  But I would never buy it again.  It's just acetone which I always have on hand;  Second, the glue will last twice as long before hardening in the bottle if stored in a refrigerator.

add a pinch of baking soda.

Try ashes, incense ashes,  better than baking soda.  Saw dust works too.  Finer the particle, the better it is.

If we really want it to cure fast, I believe we need to add a nucleophile that can initiate the polymerization.  The basic nature of the baking soda comes close, but I imagine it is too bulky to act as a nucleophile. The wood ash makes sense as it would be potassium carbonate, the potassium being bigger than sodium and, thanks to HSAB theory, further out of the way of the anion.  Someone should try household ammonia, I bet it would work really good.  I forgot most everything I once knew about chemistry, so perhaps I am wrong.

Wow, as ever this forum is a wealth of information from people far smarter then I am. Been meaning to buy some activator to give it a try, didn't realise I already had a bottle of the stuff :)

if you want superglue to  set  faster than a fast thing forget your bicarbonate of soda ,forget your incense ash,just add a bit of skin to it, glue always sticks  your fingers together  much faster than the bits your trying to glue

It still works perfectly every time I go to use it. Brilliant stuff  :-+ I really like the Power Gel version as it meets many varied needs. I learnt many years ago that superglue lasts longer when stored in a fridge.

  X2.  I keep mine in the fridge and I've never had any harden by itself.  The tube that I have now has been in there for several years.

Good point. Super Glue is slightly hydroscopic and reacts to moisture.
