Dynamic Surface Tension and Surface Energy in Ink

WebSurface free energy (SFE) is the work that would be necessary to increase the surface area of a solid phase. SFE has a decisive influence on the wettability of solids by liquids. ... As … WebA surface with high surface energy is typically very amenable to adhesion. Goniometers associate a number to surface energy by measuring the contact angle. This makes it a quantitative approach that offers abundantly more data than either a water break or dyne ink test. It is also repeatable, reliable, and (for the most part) non-destructive. WebSurface Tension Test Ink Makes Measuring Wettability Easy. Surface tension is one of two key factors in proper substrate wetting (the other being surface energy ). Tension is what causes liquids moving to form into a spherical shape, as if they are surround by an elastic membrane under tension.
