When I use a CA finish I cut off a finger of a nitrile glove and put it on my forefinger, apply a drop of CA and finish away, repeating as necessary. Usually no problems. Today I got a little careless. A whole bunch of thin CA found its way onto my finger, most of it wicking down to the fingernail side. After a couple of seconds I couldn't get that finger condom off fast enough. Be careful out there. A little out of focus, but you get the idea.

Been there, done that, Hurts like H(the dickens).

I've seen your work and it's beautiful.... I don't make pens any more, but when I did, I didn't cover my fingers, I use little squares of foam padding that comes wrapped around electronics... makes a perfect pad to spread CA.... rarely used thin CA in my finish, preferred the medium... even now every time I use thin CA, invariably wind up with it all over my fingers.
If I ever wind up being finger printed again, probably won't have finger prints... they're either burned off or covered with CA.

Heal well.
 
I used to wear disposable gloves when working with CA, but I would occasionally run into problems when a hole developed, similar to what you experienced. Now, I go gloveless and take care to avoid contact. If I do get a little on me, it seems to be less of a problem when there is no glove holding it against my skin. I use a folded Bounty paper towel piece to apply my CA.

Thank you, Chuck, as is your work. Funny, I don't do bowls anymore.
 
This was glue that was on the outside of the nitrile. It was not next to my skin.

Was the Glove Wet or Damp, as moisture I believe activates and accelerates the Chemical reaction of CA.
I use the little Zip Loc bags that the components come in over my finger, to hold a piece of 4 folded Kitchen Paper to apply my Thin CA.
So far No Drama.

Few things worthy of note here.


A) this is why medical grade CA is far superior than standard ECA. heat is ugly and does ugly things, not just to your body as you found out but to pen blanks as well.

B) Acetone accelerator further adds to the heat problem. It causes the CA to polymerize FASTER and thus more brittle.

C) I made a video in Facebook some time back showing me adding CA ( BSI Super Gold ) my bare skin and allowing it to polymerize, no problems with blisters burns or the like. I then made a second video using the same CA wig insta-set, it's naphtha based and not acetone. I sprayed my hand and there was no blisters, burns or the like. I would not DARE do that with any ECA based products.

Brian,

The only thing the finger condom was wet with was thin CA. It was humid outside, however, if I remember correctly. There was no tear in the nitrile except where I used scissors to cut the finger off of the glove. The excess CA cured on the outside of the nitrile as I was applying CA with my finger pad side. No burns or heat there.

I used to use the same method as you, but changed because I felt I was wasting too much CA as it got absorbed into the paper towel. I did burn my finger a couple of times using that method. No blisters, but it got real hot. I switched to craft foam for a while, but could never get a finish I was happy with. I switched to using nitrile a couple of years ago after reading a post from a member here. I don't remember his name, but I think he was in Japan.
