The Right Glue For The Job: Know How To Select Adhesive For Foam Projects

Whether you’re rebuilding an engine or helping your child with a school project, things always go better when you have the right tool for the job. This is true in the world of foam as well, from at-home DIY projects, to businesses making custom couch cushions, foam mattresses, or foam rubber gaskets.
Foam Factory, Inc. offers a wide range of foam products, and with them, spray adhesives designed to work best with each foam type they offer. This particular post will help you better understand why something so seemly simple is surprisingly complex, and how to select the right product with our detailed breakdown that helps make sure you always have the right adhesive for the job.

First, a little background on why bonding foam is such a unique situation:

The need for different types of adhesive can be attributed to foam’s diversity. In terms of feel, appearance, and performance, open-cell foam and closed-cell foam differ to a substantial degree. However, the dissimilarities aren’t just cosmetic, as the differences between foam types are due to individually unique chemical and molecular structures. So while open and closed-cell foams are still part of the same family, being made of very different compounds creates a range of variables when they need to be manipulated. In this instance, it impacts how a foam will react to adhesive. Depending on foam type, some adhesives may not create a bond strong enough to last, while others can have a physical reaction and damage or destroy the foam.
Fortunately, manufacturers have recognized the unique issues in bonding foam, and special adhesive formulations exist for properly bonding all different types of the material. Of course, having multiple adhesive options without knowing which works best for your application presents its own issues. To make things easier, we’ve created an itemized breakdown of our three spray adhesive varieties.
Under each type of spray adhesive we carry, we’ve listed and linked to the foam types it works best with, as well as what it should not be used with. Whether bonding two pieces of the same material or gluing to most substrates, simply find the foam you plan to work with, and you’ll know the correct type of spray adhesive to use with your project!
