Description

Wet Powder Black – Latent Print Developer for Adhesive Surfaces
Our professional Wet Powder Black offers a high-contrast solution for developing latent fingerprints on difficult, light-coloured adhesive surfaces. Forensic investigators and laboratory technicians use this pre-mixed, thick liquid to process evidence that standard powders often fail to reach. Consequently, this reagent serves as an essential tool for recovering ridge detail from the “sticky” side of tapes and the interior of medical gloves.

Versatile Application on Adhesive Evidence

You can use Wet Powder Black to develop high-fidelity prints on a wide variety of materials. Because the formula specifically targets residues trapped in adhesives, it ensures excellent friction ridge detail.
  • Tape Processing: This solution works effectively on clear, cellophane, and masking tapes. It also produces superior results on white duct tape and nylon-reinforced strapping tapes.
  • Glove Examinations: You can apply the liquid to the inside of light-coloured medical-style or rubber gloves to recover prints from the wearer.
  • High Contrast: The black formulation provides maximum visibility on light or transparent adhesives. This ensures the ridge detail stands out sharply for forensic photography.
Professional Application Process
We supply Wet Powder Black as a convenient, pre-mixed solution. Therefore, you do not need to measure or mix any chemicals before use.
  • Simple Application: First, shake the bottle thoroughly to ensure a consistent texture. Then, apply the liquid to the adhesive surface using a Tetra washable brush or a squirrel hair brush.
  • Rinsing: After a brief application period, gently rinse the surface with cool tap water. This wash removes the excess liquid while leaving the developed print intact.
  • Indefinite Shelf Life: This product is highly stable and offers an indefinite shelf life. Thus, you can keep it in your forensic kit for long-term use without worrying about chemical degradation.
Safety and Storage Standards
While this product is easy to apply, you should always handle it in a controlled environment. We recommend using a tray to catch the rinse water and wearing appropriate personal protective equipment (PPE). Store the bottle in a cool, dry place to maintain its optimal consistency for future investigations.
