The ACCU DYNE Applicator™
This tool’s Teflon® coated surface makes it ideal for dyne testing – no attraction to or contamination from the applicator affects test results. Remarkably fast and easy cleanup saves time and cleaning supplies.
Description: The blade of this applicator measures only 0.5 x 0.5 x 2.5" (13 x 13 x 64mm). A 1.5" (38mm)wide precision ground gate is centered on each of the four edges. This restricted passage channels the flow of the dyne fluid through the gate while limiting the wet film thickness applied to a maximum of only one half of one mil (0.0005", or 12.5 microns).
This tool can produce high quality drawdowns in a confined area, making direct benchtop testing a reality (for best results, we strongly suggest use on a drawdown platform). All four gates are precision ground to the same clearance to facilitate quicker test-to-test turnaround, and to provide the longest service life. Packed in a cushioned protective container.
Use: To perform the dyne test with an ACCU DYNE Applicator™, first stand the applicator upright on the film sample, then apply a short bead of surface tension test fluid from a dropper bottle directly to the sample surface, as shown above. As soon as possible, the applicator is then drawn down over this bead, spreading it over the surface, as shown in the second photo. Determination of dyne level by wetting vs. beading is identical to the test procedure shown here
