First Contact Pozilift - Latent Print Lifting Solutions and Criminal Forensics


Points preserved & Archived.



First ContactPolymer Printlifting Quick-Dry Solution is a uniquely suited to preserve and collect latent prints from surfaces which have been historically difficult to process such as curved surfaces, mottled milk bottles, bank counters and dashboards. The liquid solution can be sprayed, poured, or applied from a pipette to preserve prints at a crime scene.

IRST 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 Solution

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. First Contact 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 First Contact™ may also be photographed for comparison, identification and preservation purposes. Prints are photographic positives, not negatives! Ask about our anti-yellowing nanoparticle additive.

In summary:
First Contact 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
First Contact Printlifting Polymer Solution is easy to use. Original 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 placing liquid First Contactonto the dusted print with a pipette.

Spray Formula 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 non-level surface.

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.

NOTE : The solvents in First Contact while considered safe, will dissolve some plastics and First Contact cannot be used on items like CD’s or polycarbonate lenses found in most eyeglasses.
