I'm not a chemist but I believe that cyanoacrylate is just another name for a polyisocyanate resin . This stuff not only irratates your lungs but is absorbed into your system through skin and membranes where it affects (permanently) your liver and nervous system.There are alot of dead body shop workers due to isocyanate exposure and in the painting industry it is commonly known that the only way to keep this stuff out of you is a comlpete suit and air supplied resparator. But it is strong and fast. Any input on this issue would be appreciated. I'm also interested in more details on the alphatic glue that Chris mentioned earlier.
