Characterizing water repellency with dynamic contact angles

This webinar explores the importance of dynamic contact angle measurements in understanding and quantifying water repellency on various surfaces. It highlights why traditional static contact angle measurements are often insufficient and demonstrates practical methods for measuring advancing and receding contact angles, providing real-world examples from coatings and textiles to illustrate the value of dynamic analysis.
