Paints and varnishes - Wettability - Part 7: Measurement of the dynamic contact angles and the roll-off angle on a tilt stage (ISO/FDIS 19403-7:2024); German version FprEN ISO 19403-7:2024
Abstract
This document specifies a method for the dynamic measurement of the roll-off angle of a liquid drop on a solid surface on a tilt stage. From the dynamic measurement, the advancing and receding contact 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.
