Tonight, while applying CA to a pen using a folded over piece of paper towel as a swab, the CA -for reasons as yet unfathomed- gushed out.
It went through the towel onto my fingers, picking up enough cellulose and moisture on the way through to set instantly.
CA sets up exothermically.
I now have rather sudden and definitely painful blisters on two fingers which were stuck to the paper towel for upwards of two seconds. When I pulled one towel section off, some of the skin had been cooked and came off with it. Deep enough to bleed.
My first reaction was to thin the stuff (thus spreading the reaction out over a larger area) with the bottle of CA solvent I keep at my lathe. I still think that this might have saved the day but I found that, squeeze though I might, I could only get one tiny drop at a time out of the nozzle on the bottle. USELESS!!!!
The nozzle has now been snipped far enough down that I can get about half the contents out with one squeeze.
I will continue to use CA as a finish, but I need to figure out a practical (ie, simple enough to use reliably without obvious hazards of its own) way to keep this from EVER happening again. There is a large puffy area of skin on my finger tip ... flesh that cooked while still attached but that did not pull off when the rest did.
I do NOT want a reprise of this event.
Just a 'heads up', gang. I had about 1/4 second warning that things had gone sour (noting the excess glue coming out) before things went to pot.
Be careful out there.
