Picture this: You are working on a new project that requires a different glue than you are used to working with. You contact your glue manufacturer and they make a glue recommendation.  Now what?

The next step should always be to run a glue trial alongside your glue manufacturer in your facility. Here is why...

All glues are not created equal. Each has a unique make up - kind of like a fingerprint. They each have a specific formula with varying specifications including: viscosity, color, pH, tackiness, open time - the list goes on. 

While you are an expert in your industry, you shouldn't be expected to be an expert in glue chemistry too. That's our job.

It's best practice to have a glue expert come to your facility to run initial glue trials alongside your equipment operators.  Here are a few reasons you would want to trial with a glue expert:

1. Adjust Glue Temperature Settings - equipment settings can be a little tricky. A glue expert will offer guidance on what temperature range will provide the best glue performance. Running glues at the appropriate temperature will play a major role in how the glue will perform with your substrates. If the glue is too cold, it could set too quickly. If it is too hot, it could burn the glue. 

2. Confirm Glue Viscosity Settings - each glue has a different recommended viscosity. A glue expert will have the tools necessary (like a refractometer) to check the viscosity of the glue and make changes as needed. If the viscosity levels are not set properly, you could run into issues with dirty equipment, or pop-opens.

By measuring the glue film thickness with a mil depth gauge, we can make recommendations on how you could save money by applying less glue. Applying too much glue could also cause issues with your equipment. Make sure you're not applying more than you have to. 

These are the three major benefits of running your glue trials with a glue expert. This is completely free training for your team.

In the long run, proper glue training will help keep you from using too much glue, keep your equipment running smoothly, and make sure you provide the best finished product to your customer.
