Working with adhesives can be notoriously tricky. When we get calls about why a customer’s glue isn’t working, it could stem from various factors. If you believe your protein glue application isn’t running as optimally as it should be and want a second option, here are some of the questions a glue expert is likely to ask when troubleshooting your adhesive application.
Temperature is one of the most essential factors in protein glue application. Running your glue at a lower temperature can cause the glue to set too quickly. On the other hand, too much heat can extend the drying time or possibly burn your glue.
Be sure to take the temperature of your adhesive during production regularly. Don’t rely on what the temperature gauge on the machine says alone; test it! Check the temperature of your glue pot and rollers with a thermometer often.
One of the best ways to check your glue during production is to use a refractometer. This simple to use handheld tool measures the percentage of solids in protein adhesives.
Measuring your solids lets you know if you have the correct glue to water ratio for proper adhesion. Too little water can cause a lot of glue build-up, while too much water will reduce adhesion properties.
