There is no solvent in CA glue. The stuff in the bottle is pure monomer, plus some stabilizer and in the case of thickened glue a thickening polymer like styrene. Curing involves hooking all the small monomer molecules together to make very long polymer molecules and everything in the bottle become part of the solid....no evaporation involved. Water(nano amounts), and especially amines such as would be found on protein is what gets the reaction started.

Well, it may be that unscrupulous supplies dilute the stuff but that owuld not be the case with a reputable supplier.

While on the topic of CSI....If finger prints are exposed to CA fumes the stuff in finger prints initiates polymerization and in time a CA pattern of the finger print will develop and become visible.
