^^^^^^^^^^^^
That might be part of it, but I recall reading in some previous discussions
that some vegetable fibres, like cotton, can trigger the reaction. This
might also be related to why CA glue practically ERUPTS when it is flowed
into a pile if sawdust or woodchips.

I once made the mistake of spreading some CA glue with the corner of a
cotton rag, wrapped around my finger. The stuff cured very fast, bonding my
finger to the wood, and generated enough heat to raise a blister. (There is
no way to let go of CA glue that is curing.)
