Paints and varnishes. Wettability - Measurement of dynamic contact angle Ingestion-build-109673 together with the state variables1 Scope This document specifies a method to measure the dynamic contact angle with an optical method. The advancing and the receding angles are determined. By means of this defined measurement, the wetting and dewetting properties can be characterized. It can also be concluded on the morphological and chemical homogeneity of interfaces.
