The Surface Analyst's Innovative Method of Depositing Water to Measure Contact Angle: Ballistic Deposition
Discover how the Surface Analyst's unique method of depositing water onto a surface enables precision contact angle measurements on real-world surfaces. The forces acting on a liquid drop in contact with a surface can be represented as the surface energy of the solid, the surface tension of...

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...
