Forensic Casting Materials
Mikrosil, the finest tool mark casting material in forensic science
|The Mikrosil has been developed to give good rendering of small details, good contrast for microscopical observation, good releasing ability for the cast, and short setting time. These properties are of special importance in cases of very shallow marks especially marks with small details, requiring large magnifications. Magnifications up to 70 times are possible to achieve without interfering the material texture. Mikrosil comes in two parts; the basic and the hardener. Equal lengths of both parts are mixed together between 30 seconds and 1 minute. When mixture begins to thicken, it should be applied within one minute. The setting time is approximately 6 minutes. Mikrosil does not stick to any surface except to itself.
Laboratory tests have shown that in many cases comparison of Mikrosil casts is often better than direct comparison of marks.
Mikrosil is available in four colours: brown, grey, white and black. We recommend brown Mikrosil for general toolmarks examination, grey for forensic armoury, white and black for print lifting after dusting from difficult surfaces. We keep all colours in stock available for immediate delivery.

AccuTrans-casting silicone (polyvinylsiloxane) comes as dual 75ml cartridge. Cartridge is inserted in a dispensing gun, and a mixing tip is fixed at the cartridge. Buy pressing the trigger, accutrans is extruded equally from both cartridges, and mixed through mixing tip. Mixed accutrans is spread over the area of interest. A wide spreader is available for larger areas. Setting time 5-8 minutes. Once set accutrans stay flexibile keeping the finest details. Accutrans is available in brown, black, white and clear.
