Theta Flex Optical Tensiometer with 3D TopographySurface cleanliness is an important topic in many industrial areas, it is especially needed in applications such as coating, painting or printing where something is added on top of the other material.

If the surface where the coating is applied to is not clean, the adhesion between the coating and the substrate is typically poor.  There are many ways to ensure surface cleanliness in industrial settings, such as degreasing technology, ultrasonic cleaning, plasma cleaning but how can you be sure the cleaning process has been effective?  Or are you spending too much time ensuring the parts are clean when less would be enough?

Contact angle measurements offer a fast and sensitive way to evaluate the effectiveness of different cleaning processes.  It can also be used as a tool for quality control to ensure suitable surface properties.
