Hardness and Flexibility of Coatings

What is hardness? Hardness is the resistance of a coating to a mechanical force, such as pressure, rubbing, or scratching. Therefore, the term "hardness" in coatings often leads to misunderstandings.

A coating should have a certain hardness, but, on the other hand, it should also have a certain elasticity or flexibility.

In order to be able to determine the hardness and flexibility of coatings various test methods are shown in the webinar.
