A Comparison of Dyne Inks with the Surface Analyst™

Written by Emily Leporati

Utilization and Road Blocks of Dyne Inks

Manufacturers often employ dyne test inks, used for measuring wetting tension, to estimate surface energy (and therefore, surface cleanliness and treatment level). If you have ever used dyne, you know that applying these inks to your surface requires experience, training, and subjectivity.

Dyne inks are imprecise and subjective

Dyne inks provide an estimate of surface energy; the Surface Analyst™ produces a rapid, precise, and automated measurement.

To begin, you will need to identify which type of dyne testing fluid is suitable for your substrate. Once you apply it, the fluid will either form a continuous film on the surface or draw back into droplets. The user can only determine exact surface energy by applying a range of increasing or decreasing values of dyne test fluids.  As a result, these wetting tension measurements' subjectivity and inconsistentcy lead to imprecise results. Furthermore, by their very nature, dyne inks are destructive to the substrate itself.

Therefore, dyne inks are not an ideal solution for the factory floor. Nor are they the best choice in the quality assurance and process control of any surface cleaning, surface treatment, bonding, coating, or printing operation.


The Accurate, Quantifiable, and Objective Alternative to Dyne Inks

Contrastly, the Surface Analyst automatically calculates contact angle measurements by dispensing a droplet of highly purified water onto any surface. Within 2 seconds, the handheld instrument automatically and precisely calculates the contact angle measurement of your surface.

By providing surface energy and cleanliness data in a precise, controlled manner suitable for process control and statistical quality control. The Surface Analyst is now being used by some of the world's leading aerospace, automotive, consumer goods, electronics, and medical device manufacturers.
