What is a dyne test? Why is this test important? We get questions like these often, and to better explain this testing method we went right to the source. We have discussed dyne testing [in the past](https://blog.lddavis.com/how-to-dyne-tests). But, of course, there is much more to discuss about dyne testing beyond how it relates to our gelatin glue applications.  [Read More \>](https://blog.lddavis.com/in-depth-look-at-dyne-testing) [![LD Davis Blog](https://blog.lddavis.com/hubfs/How%20To%20Measure%20Dyne%20Levels%20In%20Substrates.png)](https://blog.lddavis.com/how-to-measure-dyne-levels-in-substrates) [Posted by Maria Ceschan on Sep 4, 2018, 8:26:00 AM](https://blog.lddavis.com/author/maria-ceschan) ## [How To Measure Dyne Levels In Substrates](https://blog.lddavis.com/how-to-measure-dyne-levels-in-substrates) Dyne Levels play a major role in proper adhesion, and here is why: The Dyne Level of a material is called its surface energy. When glue is applied to a substrate, its “wettability” is impacted greatly by its surface energy and that of the substrate.   [Read More \>](https://blog.lddavis.com/how-to-measure-dyne-levels-in-substrates) [![LD Davis Blog](https://blog.lddavis.com/hubfs/How%20To%20Use%20Dyne%20Pens%20To%20Determine%20Surface%20Energy.png)](https://blog.lddavis.com/how-to-dyne-tests) [Posted by Maria Ceschan on May 16, 2017, 8:59:15 AM](https://blog.lddavis.com/author/maria-ceschan) ## [How To Use Dyne Pens To Determine Surface Energy](https://blog.lddavis.com/how-to-dyne-tests) In order for your glue to perform properly, it must be able to penetrate (or "wet") your substrates. Some substrates are more difficult to penetrate than others. This is a result of varying surface energies.
