As many manufacturers know, using protein glue in production is a bit of a balancing act. Apply adhesives require operators to consider several variables to ensure it has the proper adhesion. When using natural protein glue, you mainly have to think about three aspects: temperature, viscosity, and the amount of adhesive applied.

When applying protein glue, temperature plays a significant role. It’s important to make sure you’re keeping your glue at an optimal temperature to have good adhesion, but sometimes accidents can happen. Here is how to identify, clean up, and avoid burning your protein glue to keep your manufacturing process running smoothly. 

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?
