So, I've been building plastic ships for years, using CA for attaching PE parts, rigging, tiny details, etc. with no effects except for occasionally sticking my fingers together. I began working on wood boats and ships about 10 years ago, also mentoring kids at the Science Olympiad program at school building bridges, towers and boomilevers. It was when I started working with wood that I noticed the adverse effects of CA. When applied to wood, if you look carefully, you can actually see whisps of either smoke or fumes rise from the CA application point. There must be a reaction when the CA comes in contact with the cellulose in the wood. These are the fumes that seem to be the culprit. Secondly, I found another reaction - FIRE! I had spilled some CA on the glass plate I use for a work surface, so I reached for the roll of paper toweling I keep on the bench and wiped up the spilled glue with the hope I got it off before it set up and required scraping to get it off. I layed the paper toweling off to the side (fortunately not in the wastebasket). Within a few seconds there was considerable smoke / fumes rising from the paper toweling, very irritating to the eyes and nose. Within a minute the toweling had actually caught fire! Again, it must be the cellulose in the toweling reacting with the CA?
I don't know, but I sure am more careful and aware of what I'm doing when working with the stuff, especially around wood and certainly around paper toweling. I now also use a small fan to circulate the air in my modeling room away from my face, or, when it will be convenient, I will do the work in my spray booth that vents to the outdoors just like I do when spraying enamels or lacquers ( even water based paints ).
Just be aware and careful with this stuff folks.
