Wetting test

In surface technology, the wetting test plays a central role in the characterization of surfaces and their interaction with liquids. This test makes it possible to analyze the wettability of surfaces by evaluating the behavior of liquids on the tested materials.

The aim of a wettability test is to measure the contact angle between a liquid and the surface. A small contact angle indicates that the liquid is well wettable and spreads on the surface, while a larger angle indicates a lower wettability, whereby the liquid tends to remain in droplet form.

Understanding wetting properties is of great importance in surface technology. It enables engineers and materials scientists to predict and optimize the performance of coatings, inks, adhesives and other materials applied to surfaces. Targeted modification of surface properties can be achieved through coatings, plasma treatments or other surface modification processes to achieve the desired wetting properties.

In industrial applications, the wetting test is also used to ensure the quality of surfaces in relation to printing processes, painting or adhesive bonding. The results of such tests help to optimize the selection of materials and process parameters in order to achieve the desired functional properties of the surface. Overall, the wetting test is an important tool in surface technology for adapting materials specifically to the requirements of different applications.
