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.

The second webinar will take place on December 4th, and the date for the third part will be announced soon.

What we are discussing

You will learn how the wetting world was missing out for decades by neglecting the dewetting side and how the Stood-up Drop fills the gap. You will get to understand what the difference between wetting and dewetting analysis is and what the recently receded contact angle (RRCA) tells you. 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.
