--- title: "WBN The Stood-up Drop: Widening the scale by capturing dewetting" description: Join our webinar about the Stood-up Drop which captures dewetting with the recently receded contact angle (RRCA), a revealing material characteristic. --- [![KRÜSS Scientific - Explore the World of Surface Science](https://visit.kruss-scientific.com/hubfs/blue_logo_kruss-01.svg "KRÜSS Scientific - Explore the World of Surface Science")](https://www.kruss-scientific.com/en) ## Focus Webinar # **The Stood-up Drop** ##### **Widening the scale with a new method for capturing dewetting** Have you ever wondered why you sometimes don‘t see a big change in wettability for process parameters such as surface treatment duration? The reason is that, focusing on *wetting* in QC and research, we looked only with one eye into solid-liquid interactions. In reality, properties such as coatability, purity, or adhesiveness often correlate stronger with *dewetting* then with wetting. At KRÜSS, we have developed the Stood-up Drop to measure dewetting by means of the recently receded contact angle (RRCA) as an ideal test criterion for changes in material surfaces. Join the first webinar of our **3-part Stood-up Drop webinar series!** Learn how this method provides insights that help enhance your surface optimization processes.

You will dive into the first of many use cases where the **Stood-up Drop strongly correlates with surface chemical parameters** relevant for QC as well as R&D.   ## **What know-how you will gain** - What there is to do if the contact angle doesn’t change with the surface treatment duration, adhesion behavior, or other parameters that are supposed to influence wettability. - Measuring the RRCA with a liquid jet: user-independent dewetting analysis with great ease of use. - Seamlessly integrating dewetting measurement when already working with a KRÜSS Drop Shape Analyzer. ## **Webinar on demand** Register now for this first webinar on demand of our **3-part webinar series** hosted by Dr. Thomas Willers (Director Product & Business Strategy).
