Summertime is here. While many of us are looking forward to the warm weather, that extra heat and humidity can mean manufacturing challenges for some. You’ve probably noticed the consistency of your glue change during the warmer months if you’re using protein glue.

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. 

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?
