Measuring contact angles and absorption processes on wettable and non-wettable powders using optical contact angle and contour analysis

Using the optical contact angle and contour analysis system OCA from DataPhysics Instruments, the wetting behaviour of hydrophobic or non-wettable powders with a contact angle above 90° can be analysed easily and reliably. In this application note, the wetting behaviour of wettable and non-wettable powders were studied using the example of FeSi powders.
