The Adorama Cyanoacrylate (Thin Viscosity) is used in the fuming process to develop latent fingerprints. This technique is particularly useful with textured or other difficult surfaces. The easy to use accelerant allows the rapid fuming of cyanoacrylate in the processing for latent prints. It is great for processing large areas such as the interior of a vehicle or rooms in a house. Store in refrigerator to prolong shelf life.
