A surface that has been properly prepared for coating, painting, or adhesive bonding will have a certain average contact angle that is determined primarily by the chemical composition of the surface. Because of slight variations in the surface composition combined with the variation inherent in any measurement device, the contact angle will vary slightly from point to point.
This paper discusses how to account for this variability to make decisions about surface quality and acceptability.
Read this in-depth white paper to understand how you can implement contact angle inspections and confidently make surface quality decisions in manufacturing.
