Many times a fingerprint will be left on a surface which is porous, fragile, textured or contoured making them very difficult to collect with tape. Since the 80’s we at NCIT began using a series of products intended
for “toolmark casting” in the collection of fingerprints after
they have been rendered visible, usually through dusting with conventional or magnetic powders. Products such as Mikrosil, a synthetic two-part catalyst activated casting material are easy to use and relatively inexpensive to purchase. Prior to mixing and use, the product will last a year or so if stored at “comfortable temperatures”. Avoid heat and extreme cold. After mixing, and correct application to the
previously developed print, the cast will last indefinitely and preserve superb detail of the print.
