Troubleshooting: Poor Glue Penetration

If you work with P.O.P. displays or sample boards, chances are you have come across a situation where your adhesive just doesn't seem to hold your turn-ins. This is called "poor glue penetration" and believe us, we know how annoying it can be. One of our customers out of Georgia was having this same problem with their sample boards. Find out how one simple change helped to solve their turn-in troubles.

The Problem

This customer was using cake glue (aka animal or protein glue) for paper to chipboard without any problems. For a new project they were working on, they had to switch over to gluing paper to corrugated and they could not get the turn ins to stick. OH NO!
frustrated Don't stress - like we said, it was an easy fix.

The Solution

Our Territory Manager, Bill McCalla, visited their facility to investigate.  He found that the temperature of the glue at the rollers was too low.  The glue was setting too quickly and would not allow it to penetrate into the more difficult corrugated material. At Bill's recommendation, the temperature of the glue was raised to 145 F and ran perfectly.

How to Check Glue Temperature

Wondering the best way to check the temperature of your glue? One simple way to measure your glue temperature is with an infrared thermometer. "An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance." (Wikipedia)

Not sure the best temperature for your glue? If you need the technical data sheet (TDS) we would be happy to send it to you. Otherwise, you can always reach out to your sales representative and they can go into more detail about the optimal application temperature. Check out more of our glue tips and tricks here.
