What are dyne pens? What is a dyne test? Why is this test important?

We get questions like these often, and in order to better explain this testing method we went right to the source.

We have discussed dyne testing in the past. In fact, one of our most highly read blog posts discusses how to perform a dyne test. But, of course, there is much more to discuss about dyne testing beyond how it relates to our gelatin glue applications. 

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.  

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.
