Why Water-Based Adhesives?

Water-based adhesives are formulated to suit a multitude of uses.

Considered the workhorse of the adhesive industry, water-based glue is economical and versatile.

With their ability to adhere to a variety of surfaces and materials, they can be dialed in to suit a wide array of customer equipment and performance requirements.

But sometimes, water-based adhesives fail. Why? Read on.

What Causes Water Based Adhesives to Fail?

1. Poor Setting Speed

The first reason why your water-based adhesive isn’t working is because the glue may have set at a poor speed – either too quickly or too slowly.

How to fix it

  • Check if product has been diluted
  • Check if product has been stirred thoroughly before use
  • Check viscosity increase due to aging and dilute if necessary
  • Check for excessive application and reduce if necessary
  • Contact your technical sales representative. We have the expertise to troubleshoot.

2. Poor Adhesion

Another reason why your water-based adhesive might have failed is because of poor adhesion due to improper viscosity or compression.

How to fix it

  • Check viscosity increase due to aging and dilute if necessary
  • Check for uniform application pattern
  • Check compression (too little or too much)
  • Check head space if sealing boxes. Too much head space can hinder compression.
  • Check for improper scoring, which can cause springy flaps (If this is the case, you may need faster, tackier adhesive)
  • Check if board has proper glue assists (not coated where adhesive is applied)
  • Change stock or adhesive
  • Contact your technical sales representative.

3. Excessive Penetration or Holdout

The last reason why your water-based adhesive is not performing as well as it should be, is because there has been too much penetration or holdout in the application.

How to fix it

  • Check viscosity. Adhesive may be too thin or too thick
  • Increase or decrease application as required
  • Change stock or adhesive. Some stock is significantly more porous than others.
  • Contact your technical sales representative.
