way to determine the surface energy of polymer surfaces. The polar
portions of the surface energy responsible for the adhesion of
coatings can be quantitatively collected by means of the contact
angle measurement. In this way, wetting and adhesion properties
can be predicted. Compared to the use of test inks to estimate the
surface free energy, the present method has the advantage of providing
a greater accuracy and let to additional information the polar
and dispersive contribution of the surface free energy, which
governs printability or adhesion. At the same time being
independent of the experimenter, thus ruling out subjective influences.
