Have you ever been part way through production and completely run out of protein glue (hide glue)? Or maybe you've ordered way glue more than you needed and you had to dispose it because it expired?

Most times we get caught up in asking the question: what does the glue cost? But, perhaps, the more important question to ask is: what is the cost of using the wrong glue?
Maybe you were working on a project that had more difficult substrates? Or maybe you were starting to run out of glue? No matter what the reason for blending protein glues on-site, there are some drawbacks that you should keep in mind before considering this.
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.
