You're running animal glue on your production line and all of a sudden, it doesn't seem to be working properly. Your wraps aren't sticking and the glue seems to be drying too quickly. What happened?

The mil depth gauge (wet film gauge) tool can be used to properly measure and assess the film thickness of L.D. Davis protein glue.

One of the best ways to get the most out of your adhesive is to make sure that you are applying the appropriate amount to your substrates.
