Gorilla glue
 

Does anyone know if this stuff is safe to use and if it works?

i don't know how safe it is in a tank, but i have used it in woodworking and i've even used it on a pair of shoes. whatever you do, don't get it on your hands. that stuff is cray strong, definitely gorrilla strength. also you have to be careful when you use it b/c it expands as it sets up.

If it has the same bonding agent as crazy glue it should be fine.
Now dont quote me on this but i believe its cyanoacrylate

Kabong is correct. As long as the main active ingredient is Cyanoacrylate, you will be fine.

Gorilla glue is a polyureathane glue. Once it has cured it is non-toxic . It is excellent for woodworking but has to be applied in the manner suggested by the manufacturer. What do you plan on using it for?

Apparently it has a 2 - 3 hour cure time so IMO it wouldn't be any good for mounting frags.
Now if your building a stand then it would be great!!

Well I was wanting to know if it was OK to use for mounting frags but if it takes that long to cure that is out of the question. If it was me using it for woodwork then I would need a lot more that the silly little bottle it comes in - try a 5 gallon pail to put my mess together.
Thanks for your replies - I went with the super glue gel - it just required that I make an additional trip to town to get it (one hour round trip)

Loctite SUPERGLUE. Gel control

I used to use regular gel superglue till i came across the loctite :) it's the thickest gel,no mess,super dispenser,all around cadillac of superglue's.Never using anything else.

I think if you use a tray with water that they can sit in for 1/2 an hour then it would be fine. I am going to play with gorillia glue as I have been wondering about it myself. there are no acids and it is non toxic so I think it would be ok. but I am going to try gluing up some small chunks of rock to see if it will set up under water and how long it takes to be reasonably hard.
