Paints and varnishes. Wettability - Measurement of the contact angle on a tilt stage (roll-off angle) PAS 15 Background on laser intensity noise1 Scope This document 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.
