ACCU COAT Applicators™
Teflon-coated four-sided applicators; seven depth
ranges, from 0.5 to 12.0 mils, offer extended versatility
Application and cleanup are remarkably fast and easy
Supplied
in protective cushioned packaging – with reasonable care,
these affordable tools can last for years
Description: The blade of this unique applicator design measures
only 0.5" x 0.5" x 2.5" (1.3cm x 1.3cm x 6.3cm).
A 1.5" (3.8cm) wide precision ground gate is centered on each
of the four edges. This restricted passage channels the flow of
the liquid to be evaluated through the gate while metering the
wet film thickness applied. It is intended as an easier and less
time-consuming alternative to Mayer rods and Bird-bar style applicators.
These tools can produce high quality drawdowns in a confined area,
making direct benchtop testing of inks and coatings a reality (for
best results, we strongly suggest use of The
Diversified Drawown Platform). Quick changeover from gate to
gate allows direct comparisons of different coating thicknesses. Not
recommended for flexo ink proofing.
 Use: The
wet film thickness (WFT) applied can be varied, based the angle
at which the tool is held (please see the figure
at right); a 45° angle produces the greatest clearance, yielding
a wet film approximately equal to the depth of the gate. By holding
the ACCU COAT Applicator™ at more acute angles,
the passage depth is reduced, resulting in a thinner coating. In
theory,
a 22° angle produces a wet film roughly half of gate depth.
We do not recommend holding the tool at an angle steeper than 50°.
Coating rheology affects WFT; critical applications should be checked
with a precise WFT gage such as those shown here.
