Paints and varnishes — Wettability — Part 6: Measurement of dynamic advancing and receding angle by changing the volume of a drop
油漆和清漆润湿性第6部分:通过改变液滴体积测量动态前进和后退角
This document specifies a method to measure the dynamic contact angle with an optical method. The dynamic advancing and the dynamic receding contact angles are determined.
By using the measurement specified in this document, the wetting and dewetting properties can be characterized. The morphological and chemical homogeneity of interfaces can also be determined.
