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. Protein glue is composed of gelatin, Epsom salts, sugars, and glycerin. The glue is all-natural and biodegradable, so that means the raw materials can go through changes due to rising temperatures. If your manufacturing is starting to become a sticky mess, don’t worry!

We have 6 helpful tips below to help you have a successful and productive summer with your glues.

  1. Apply Less Glue

    Sounds counter-productive, right? But yes, we’re telling you to apply less glue. Protein glue sometimes takes longer to dry or set in the heat. A thinner layer of glue needs less time to dry, providing you with the proper adhesion you’d expect from your glue.
  2. Try to Lower the Temperature of the Glue

    Protein glue should be applied to substrates at a temperature of around 140-150℉ (60-65℃) in low humidity. If your adhesive is becoming too sticky, try dehumidifying the area or lowering the glue temperature to help it set faster
  3. Close the Doors

    Try to block as much outside humidity and heat as possible by closing the facility doors. Improving climate control in your facility will allow you to regulate your glue temperature better.
  4. Slow Down Production

    This tip goes hand in hand with #2. By slowing down your machinery, you provide a larger time window for the glue to set. It’s better to consistently create products at an even pace than stop production to clean messes or dispose of subpar products.
  5. Properly Store Substrates

    All unglued substrates should be kept in a climate-controlled location at your facility until you’re ready to use them. Better storage can help prevent your substrate from getting warped.
  6. Keep the Fans Going

    The cooler everything is kept in the production line, the better results you will have. If possible, use fans to keep your equipment cool. Fans can blow a constant stream of air over your machines and help regulate temperature and keep things running smoothly.
