Different types of surface treatments, such as plasma, laser texturing, or flame treatment are used to improve the wettability of the surface and subsequently the coating adhesion.
Despite a good process planning, adhesion problems sometimes occur. To catch the possible problems early on quality control processes for the treated surface should be implemented. As wettability is the most important factor indicating good adhesion, contact angle measurements are often used to ensure process quality. For quality control, contact angle measurements offer a fast, qualitative, user-independent and traceable method.
