Manufacturers are familiar with adhesion challenges when attempting to bond, paint, etch, or coat a substrate. Poorly prepared surfaces can undoubtedly produce problematic adhesion issues.
A frequent question from people who use contact angle measurements to characterize surfaces and control manufacturing processes is, “What effect does surface roughness have on these measurements?” This is a valid question, especially when dealing with surfaces that have a range of textures...
A wide variety of plasma treatments were performed on polyethylene surfaces, resulting in a wide range of total surface energies.
Contact Angle Measurements and Surface Analysis of Atmospheric Pressure Plasma Treated Polypropylene
The Surface Analyst™ rapidly obtains contact angle measurements from surfaces via Ballistic Deposition, whereby a small drop of liquid (usually water) is constructed in situ on the surface via a pulsed stream of nanoliter-sized droplets.
There are fundamental differences between an NRL-style goniometer and the Surface Analyst, most of which contribute to the value of the measurement for development and control of surface sensitive manufacturing processes.
Gage Repeatability and Reproducibility is a valued measure of a gauge’s appropriateness for use in a specific application.
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...
