Bubbles

In surface technology, the term "bubbles" refers to unwanted formations of air or gas bubbles that can occur during certain processes, such as coating, drying or curing of coatings or other materials. These bubbles can have various causes and can affect the quality and performance of the treated surfaces.

In coating processes, bubbles can occur when air is trapped during the application of the coating solution or when volatile components in the coating evaporate and form bubbles. When the coating dries or cures, these bubbles can become trapped in the coating and lead to uneven surfaces, blistering or delamination.

To minimize the occurrence of bubbles in surface engineering, various measures can be taken, such as using defoamers or deaeration systems to remove the air from the coating solution or optimizing the coating processes to control the evaporation of volatile components.

Controlling bubbles is important to ensure high-quality and reliable surfaces, especially in applications where the aesthetics, functionality or performance of the treated surfaces are critical. Therefore, methods to prevent and treat bubbles play an important role in the surface treatment industry.
