Silicone for lifting

Silicone rubber compounds for fingerprint lifting

Certain surfaces have such a texture that even with gelatin lifters, it is hard to lift powdered fingerprints in their entirety. Examples are: Hammerite painted coin boxes and polystyrene packaging material. In these cases, white or black silicone rubber casting compound can be used. The casting compound is mixed with hardener and diluant (if needed) and poured over the print developed with fingerprint powder. After the silicone rubber has cured, the fingerprint is lifted.
 
Depending on the color of the fingerprint powder that was used, white or black silicone rubber is used for contrast.
 

Silmark Black

Silmark Black is used for lifting of fingerprints developed with fingerprint powders. Light coloured fingerprint powder, for example the regular or magnetic silver or white coloured ones, contrasts well against the black background that this silicon material provides.
