Dyne testing spread
WebMar 16, 2016 · The solution is spread lightly over test material; the operator looks to see that the solid line does not breakup for two seconds. If the wetting solution stays intact … WebTest the surface energy (dyne level) of film and other nonabsorbent surfaces before printing, coating, or laminating. Also known as dyne pens, these work like a felt-tip marker. A continuous line will appear if the material meets the tester's surface energy level, while insufficiently treated material results in air bubbles and a disappearing mark.

WebSurface energy is, as you might expect, expressed in units of energy per area. Typically, it is measured in a unit called “dynes” where 1 dyne/cm is equal to 1 mJ/m. Most commonly, surface energy is measured with water. When a droplet of water is placed on a surface, it will bead up to some extent. Theoretically, if the surface energy is ...
