Paints and varnishes - Wettability - Part 7 : measurement of the contact angle on a tilt stage (roll-off angle)

ISO 19403-7:2017 specifies a method for the dynamic measurement of the roll-off angle of a liquid drop on a solid surface. From the dynamic measurement, the advancing and receding angles of the drop rolling off can also be determined. The roll-off angle plays a role when evaluating, for example, easy-to-clean or anti-adherent surfaces.
