I knew CA could get warm while it was curing but this evening I found out just how HOT it can get.

I was gluing a cable connector together (my other hobby is electronics) using some of my thin CA and managed to spill quite a bit on my hand. A few seconds later and it was very hot and painful. I shoved my hand in my bowl of water I use for wet sanding and things cooled down but not before the CA left a sizable blister on my thumb and a couple of other fingers.

I guess I will be more careful from now on.

Hmmmm

And they sell that stuff to put on wounds instead of bandage. I wonder what the difference is. When I did modeling I got a little superglue on my fingers pretty often and never noticed any heat. I'm glad to find this out.

Smitty, this is particularly true when you have been using accelerator.

CA can glue your fingers together without burning them.

Also if the CA gets on a paper towel and THEN gets glued to your hand, it gets blistering hot and VERY painful.
 
This was seepage from the connector, so it had probably already started to cure before I got it on me. Also I've noticed the thin CA gets much warmer than the medium or thick CA.
 
It can also start a fire if on paper towel which is why you should be careful when disposing of anything that ca comes in contact with. For example paper towels should go in a steel can or a bucket of water.

That's for sure. I just watched a CA saturated towel produce quite a bit of smoke as it reacted. I waited a while before soaking it in water just to see if it might ignite. Beware of the fumes from the smoke also.
 
Some paper towels are fine, while others contain some 'ingredient' that reacts with the CA to produce heat and smoke. Put a few drops on your paper towel and watch it. If you see smoke you need to find a different brand towel.

CA was invented as a surgical glue to replace internal stitches. It does bond skin very well, DAMHIKT, but can be disolved or at least softened with nail polish remover (acetone)
 
You know, I have been burned by all types of super glue, but couldn't really tell you which one burned the worst. Oh I do know, it was the one that melted the scotch tape I had on my finger to keep the glue from sticking to my skin. Yea, scotch tape fail! That hurt a little.
 
If you read the MSDS Material Safety Data Sheet for cyanoacrylate it instructs users not to wear cotton or wool clothing, especially cotton gloves, when applying or handling cyanoacrylates.

When you apply cyanoacrylate to materials made of cotton, wool, and certain yarns or fabrics, along with recycled paper towels that use rags or fabric in them. It can results in a powerful, rapid exothermic reaction. The heat released may cause serious burns,ignite the cotton product, or release irritating white smoke.

This will depend on the amounts of the above material used in the paper towel.

As too the surgical use, due to the toxicity issues of ethyl cyanoacrylate, the use of 2-octyl cyanoacrylate for sutures is preferred, but others are also used.

There are a number of general formula's for CA with standard 'superglue' is 100% ethyl cyanoacrylate:
Ethyl Cyanoacrylate
Methyl Cyanoacrylate
Butyl Cyanoacrylate
Octyl Cyanoacrylate
2-Octyl Cyanoacrylate

Read the MSDS as most can be found on line, and be safe out there!

Been there, done that, know better...now.

Medical CA is a different formula. If you use the CA used in woodworking on a cut you can injure the tissue. So bandaids work best or even just tape to hold the edges together.
 
And if you do get CA glue on your hand, DON'T use accelerant to try to get the thick stuff to dry faster because you're impatient and just want to get to work on getting yourself unstuck. That's a BIG mistake and ensures a burn!!!

We use a fingerprint scanner to get into the computer room at work. I have had to register 2 fingers as my primary finger has had issues to CA:biggrin:

That made me smile....The gym I used to go to had one of those and we couldn't get any of my finger prints to work. They're on record from military service and from handgun permit but I wouldn't want to bet that they could identify me from them anymore. They're about plum worn off.
