How Many Measurements Are Enough to Make Quality Decisions?
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...
