Mobile Surface Analyzer

Fast, automatic, and non-destructive wetting analysis with your liquids of choice

In the Flexible Liquid configuration, the MSA Mobile Surface Analyzer carries out automated contact angle measurements between freely selectable liquids on solid samples. The focus lies on non-destructive analysis with formulations such as inks, coatings, or adhesives, to evaluate their wetting behavior in real process.

Applications

• Analyzing the wetting behavior of formulations such as paints, coatings, or adhesives on solid materials

• Checking wettability of plastics, glass, ceramics, wood, paper, or metal

• Quality assurance of activation processes such as plasma treatment, flame treatment, or corona treatment

• Testing the effectiveness of hydrophobic coatings and other coatings

• Measurement on large workpieces and finished products such as car bodies, aircraft parts, or walls

Measuring methods

• Contact angle of a drop on a solid surface
• Surface free energy of a solid using contact angle data
• Surface tension using the curvature of a perfectly symmetrical drop on a circular sample pedestal
• Carrying out a measurement up to 20 consecutive times and displaying the results together

Measuring results

• Static contact angle

• Surface free energy (SFE) according to the following models: Owens-Wendt-Rabel-Kaelble (OWRK), Fowkes, Wu, Zisman, Equation of State
