Regardless of the method used, any contact angle less than 90[degrees] represents a wettable/hydrophilic surface, while a hydrophobic surface wetting angle is greater than 90[degrees] (see Figure 1).
It has also been observed that the emission of drops depends to a great extent on the static wetting angle, that is, the angle that the drop makes with the contact surface.
Wetting angle greater than 90[degrees] indicates the success of hydrophobic finishes of woven sailcloth made of PES (sample 1).

Its hydrophobic properties are especially evident at a wetting angle up to 120x.
The wetting angle increased by raising the Sb content, but, in contrast, by increasing the wt.
Wettability measurements have shown that all lead-free solders wetted aluminium surface with wetting angle below 42[degrees].
Surface energy measurements using a wetting angle technique were also used and compared with the peel data.
The best wetting angle of 18[degrees] was measured in the case of Ag substrate with the application of flux.
In judging solder joints, one of the quality aspects is the solder fillet shape and wetting angle.
