Ethyl cyanoacrylate - Wikipedia

WitrynaCyanoacrylate is the generic name for a family of strong, fast-acting adhesives that are generally labeled as "Super Glue." In fingerprint fuming, the vapors of cyanoacrylate react with the chemicals that are found in fingerprints. This reaction leaves behind a white film that can be photographed, or copied onto tape strips. WitrynaThe fume circulation method is fairly straightforward in principle; if the cyanoacrylate fumes are actively circulated around the tank, the air inside will have a constant concentration of them and all latent fingerprints in the tank will be in constant contact with some cyanoacrylate. In practice, the fumes can be forced to circulate by the free hiv and std clinicWitrynaCyanoacrylate fuming is one of the most common techniques employed for the detection of latent fingermarks on non-porous surfaces such as plastic and glass.
