Cyanoacrylate super glue reacts with the traces of amino acids, fatty acids, and proteins in the latent fingerprint and the moisture in the air to produce a visible, white polycyanoacrylate that forms along the ridges of the fingerprint. Low viscosity glues are quicker to vaporize and can thus reduce processing time, but some will thicken with age and thus necessitate a longer exposure time. Turn on the heater and close up the container. Det. What can investigators use to detect latent fingerprints without use of chemicals or powder treatments?

Set up the test sample in the corner opposite of the heater. Classification 2. The cyanoacrylate group in the monomer rapidly polymerizes in the presence of water to form long, strong chains. Without the heater, the process might take over 24 hours to complete. Facebook. As a sealer, peel off the backing and place the clear self-adhesive strip over fuming chamber hole.
