Just like with most natural products, glues have an expiration date.  You'll notice, especially with your natural glues (protein/gelatin based) and liquid water-based glues, that after they have hit their expiration date they may become moldy and unusable.

What do you do if your glue is expired?

It's August, and man is it hot.

Maybe you work in a manufacturing plant that is hit with extreme heat and humidity during the summer months. If so, there are some things you should keep in mind when it comes to running your glue in this weather. 

Summertime is finally here, you know what the means?

Beach trips, flip flops, swimming, refreshing cocktails, and protein glue? That’s right folks, protein glue also known as hide glue or animal glue.

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?
