These
are Aqueous Tracers AKA Dispersions that are usually
used to mark paper. The dispersions are suspended in
water and suitable for use in water based inks &
coatings.
Also popular in creating visually brilliant special
effects when standard long wave UV/Black Light is
applied.
Tracer
T-800-900 series are invisible in daylight and fluoresces blue
or yellow
under black light. Normal
color is milky white.
We
suggest that the Tracer be diluted by using one part
of tracer to ten parts of clean water. The mixture is
usually applied to the paper using an automatic spray
device, but can be applied by hand using a paintbrush
or an even smaller marking tool. It can also be loaded
into a shipping room marker (a smaller refillable felt
tip marker).
If
white paper is being marked, the 10 to 1 dilution may
be too concentrated and the tracer will leave a
visible mark. Dilute further until no visible residue
can be seen.
The
mark is then observed using a black light (a filtered
long wave ultraviolet light). The mark can best be
seen under subdued ambient lighting conditions - not
in bright sunlight.
After
experience with a particular marking application, the
dilution ratio can be often increased. We have some
applications where a ratio of 25 to one can be used.
Invisible marking means the
application of fluorescent materials that cannot be
easily seen in normal daylight, but become visible
when exposed to a beam of long wave ultraviolet light
that is sufficiency intense to cause visible
fluoresence to appear on the marked article.
Observations and automatic scanning
work best with subdued visible ambient lighting.
Users select invisible marking
because they do not want the mark to be seen for
appearance reasons or they do not wish knowledge about
the marking to be easily discernible.
Invisible marking is often used for
product ownership or source identification. It can
also be used to guide manual operations as in garment
fabrication using black light to guide cutting and
sewing.
Invisible marking is often used
where marks need to be placed on multicolored surfaces
that make automated scanning difficult because light
from the background prevents a clear signal from being
received by the scanner.
The purpose of scanning is for
automation. The scanner verifies that an invisible
mark is either absent or present and causes some
action to be taken based on the signal. The action
taken obviously depends on the application, but could
take the form of sending a product on a selected path
in a conveyor system or to trigger a subsequent
processing operation.
Quality Control
FLUORESCENT
TRACERS USED IN INDUSTRIAL COATINGS:
In any coating operation where the
coating film is invisible to the naked eye, uniformity
of the film or conversely, the lack of uniformity, can
be more easily detected by adding fluorescent tracers
to the coating medium and then inspecting the coatings
under black light.
Fluorescent tracer products, using
this general method to detect unwanted residues, have
found application in the removal of solder flux
containing a fluorescent tracer from circuit boards
after soldering and cleaning. Another fluorescent
tracer is often added to the final conformal coating
for a further inspection under black light to assure
thorough and even coverage.
This general approach to coating
inspection can be applied to many quality control
procedures involving electrical devices such as
potentiometers and transformers.
A host of other uses are found in
almost any field involving coatings and adhesives to
verify either the uniform presence of a material or to
detect absence of the material.
Automatic scanning devices utilizing
fluorescent tracers can be valuable in establishing
automated procedures and improving record keeping
capabilities in quality control inspection.
