WebDyne Test Pens are non-toxic and are used by operators that handle the production lines to check if a material has been treated, or not. The measurements is made accordingly to the same ASTM procedure as the test inks, so it verifies if the liquid remains spread for at least TWO SECONDS. 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 ...
