First Contact Pozilift™ - Latent
Print Lifting Solutions and Criminal Forensics
Points preserved & Archived.
First Contact™ Polymer
Printlifting Quick-Dry Solution is a uniquely suited to preserve and
prints from surfaces which have been historically difficult to process such as
surfaces, mottled milk bottles, bank counters and dashboards. The liquid
can be sprayed, poured, or applied from a
pipette to preserve prints at a crime scene.
FIRST CONTACT™ liquid matches surface contours and fixes the print without distortion. The ability of First Contact™ to follow surface features and hold particulate materials, for example dusting powders, in their exact relative orientation when the solution dries means First Contact™ can be used to lift or fix latent prints on matte surfaces, frozen surfaces, curved surfaces, and roughly textured surfaces which are historically very difficult to process.
The Answer for difficult lifts and preservation.
FIRST CONTACT POZILIFT™ POLYMER SOLUTIONS
♦ Lift high fidelity latent prints from difficult surfaces
♦ Preserves the print for future use and archiving
♦ Leaves no residue on surfaces the solvents don’t damage
♦ Magnetic or conventional dusting powders
♦ Lifts latents from mottled or rounded surfaces The Answer for difficult
♦ Prints are perfect for entering points into AFIS
♦ Works instead of Microsil and lifts a positive print
♦ Prints are photographic positives, not negatives

First Contact™ Polymer
First Contact™ polymer is a
colorless, inert, plastic film which ‘holds’ particulate material in its
matrix. This characteristic allows
lifting of dusted latent prints. The
solution is composed of designer polymers dissolved in safe, environmentally
friendly solvents. The liquid or spray
flows over surface contours, leaving no air pockets or gaps. The solution dries to a strong, colorless
plastic film which preserves and protects the dusted print.
polymer is chemically inert and heat resistant to at least 350° F, (180°
C). The dry polymer film is easily
lifted or may be left in place at the crime scene for as long as desired.
Photographs can be taken through
the colorless polymer film. Of course,
prints lifted with colorless and transparent
may also be photographed for comparison, identification and preservation
purposes. Prints are photographic
positives, not negatives! Ask about our anti-yellowing nanoparticle additive.
Polymer can be applied using various methods to fix a print regardless of
surface orientation or features, preserve it for an indefinite period,

How to use
First Contact™ Polymer Solution
Printlifting Polymer Solution is easy to use.
First Contact™ may be applied with a brush,
by pouring from the container, or using a pipette/eye dropper. Work in Photonic Cleaning Technologies labs
has found that latent prints on horizontal surfaces are easily fixed by gently
the dusted print with a pipette.
First Contact™ Pozilift Printlifting
Polymer Solution, was specifically developed to allow application to latent
prints regardless of surface features such as orientation (slanted, vertical,
or upside-down), texture, waviness, or other irregularities. Spray formula application of this quickdry
solution is fast and easy; however it requires several applications to build a
thick film which is strong enough to peel from the substrate. The first application of spray formula should
be very light to produce a tack layer.
The tack layer will dry in a few seconds and performs the following
functions: 1) fixes the print in place and 2) allows heavier subsequent
applications of polymer solution without ruining the latent print on a
When the polymer solution is dry a
strong, clear, flexible film will remain to fix and protect the print. This film is optically transparent and
photographs may be taken through the film.
The film remains on the substrate until someone actively removes it; the
print may remain in place and safely preserved while the crime scene is
processed and photographic records are completed.
First Contact polymer film removal
must be done with care to prevent the polymer film from folding onto itself;
the unsupported polymer film will behave similarly to plastic food wrap. Use a backing material for support when
removing the film if desired. Standard
fingerprint removal tape has worked for this purpose in Photonic Cleaning
Technologies’ testing labs. One could
use a sheet of paper by wetting it with First Contact
Polymer Solution and then placing
the paper on the print’s polymer film. Spray
or pour additional First Contact Solution onto the paper and allow to dry. The fresh polymer solution will form a
thicker polymer film with the existing film, embedding the paper in polymer to
provide support and prevent the film from folding in on itself. With experimentation, other methods will be
identified for this purpose.
