UV-Fluorescent Beads and Security Threads
New Embedded Identities Possible
|
|
The
possible permutations of embedded identities (identification made
through patterned taggants embedded in substrates and adhesives)
has increased significantly this week with the announcement of a
new line of “invisible” threads and beads from H.W. Sands Corp.
The Sands-Secure® brand of product offerings contains
textile filaments and polymeric spheres that are an innocuous white
color in normal lighting conditions. Strike up a UV light source
and the particles come alive with a dramatic offering of colors
making them perfect for field identification and verification of
substrates. |
Many
companies already use UV-Fluorescent particles in known concentrations
as taggants. What this offering does is to increase the color options
and provide a system of compatible particles that can be combined into
the same matrix. A security paper for instance could have blue and red
fibers with green “dots” (spheres) and a lamination adhesive could have
yellow dots with red fibers.
The
initial offering starts with two different colors of fibers
|
Normal
Light |
 |
 |
|
UV-Light
(365nm) |
 |
 |
|
| The
fibers have a maximum diameter of 100 microns and their length ranges
from 0.3 to 4 millimeters. |
And
four different colors of beads
The
beads are true spheres and are smaller than 65 microns.
