The Downfall of Dyne Pens – Not Dyne Measurements


“What’s wrong with Dyne Pens?”

You may have followed our narrative of the disadvantages and potential harms of using dyne ink pens, or dyne pens, in the manufacturing process. If you have not, you are in luck because we are going to lay them out for you again with the hope of showing you the safer alternative.

In short, dyne inks and dyne pens have been used in many manufacturing applications to help companies understand what their surface energy and interfacial tension measurements look like before and after surface treatment processing. These dyne ink measurements have been adopted in many manufacturing processes, therefore, becoming an industry standard. One main reason for their use is that they are financially inexpensive, but we can think of at least 5 reasons why this method isn’t the best option for understanding how well a surface is prepared for processing.


These are just a few disadvantages of using dyne pens in surface testing environments:

  1. Subjective testing means results may vary based on each user
  2. Dyne chemicals are destructive to the parts being tested, resulting in wasted product
  3. Results are often unrepeatable and unreliable
  4. High user skill needed to perform test
  5. And MOST importantly – Dyne chemicals can be teratogenic, potentially leading to birth defects in pregnant users

That last one was a real shocker, especially in light of the many applications that Dyne Pens are used to test surfaces with. If this is the case, “something needs to be done!” one might say.

Manufacturers haven’t had an alternative testing method to dyne inks, until now!

The Surface Analyst

The Surface Analyst is the ideal alternative; providing a fast, easy, accurate, quantitative, and non-destructive, contact angle measurement resulting in a much more seamless quality control process.

Using ‘Dyne Mode,’ the Surface Analyst even provides a dyne measurement read-out directly on the instrument, allowing manufacturers to maintain their investment in the dyne measurement language.

These are a few of the benefits of using the Surface Analyst as an alternative to Dyne ink:

  • Can be used in any environment, both the lab and the manufacturing floor
  • Measurements can be done on most materials
  • Nondestructive to the user
  • Nondestructive to the part being tested, saving in scrap
  • Provides an accurate and quantitative measurement
  • Fast and efficient–takes 1 measurement in 2 seconds

We have said it once, but it is worth noting again: the Surface Analyst speaks in dyne measurements! Not only will you be getting the best quality measurements possible, but you will be able to share them seamlessly with other involved parties.
