Different Types of Glues for Foam Sheets

Each application of foam boards is unique and therefore needs a specific agent. Choosing the type of glue to use on foam depends on the method of application, the overall process, and product requirements.

If you combine these factors appropriately, foam adhesive can impressively enhance efficiency. Different types of adhesives are based on the various chemistries that enable them. Some of the most common types include:

Epoxy Adhesives

This is a particularly strong class of glue that was initially developed for the construction of airplane components. Epoxy glues tend to work well on most surfaces like foam, concrete, glass, and plastic. In addition, the curing of epoxy adhesives virtually includes a chemical reaction between 2 components that are mixed together.

However, gluing with this adhesive can become quite messy since you’ve to add 2 parts to trigger the chemical reaction.

The 1st part of the epoxy glue is the plastic resin which is the body of the glue. On the other hand, the 2nd part is the catalyst that activates resin, thus enhancing its curing and hardening. The performance of certain epoxy glue is dependent on the kind of hardener utilized in activating and curing the resin.

It is usually best to combine the 2 parts equally in order to get proper curing. Nonetheless, you can vary their proportions by about 40% resin and 60% hardener and vice versa. Furthermore, you’ll increase the flexibility of the bond if you increase the proportion of the hardener.

On the other hand, increasing the proportion of the resin more than the hardener’s proportion increases the strength of the bond. However, this renders the glue to be less impact-resistant and more brittle.

Super Glue/ Cyanoacrylate Glue

Cyanoacrylate glues tend to adhere quickly since their curing requires the absence of oxygen and the presence of moisture. Therefore, once you press 2 items with super glue together, you squeeze out oxygen and air moisture sets the adhesive.

However, cyanoacrylate adhesives are only effective in non-porous materials like metal, rubber, ceramics, plastics, and glass.

They quickly form strong and durable bonds, although they’re somewhat brittle. In addition, they’re quite expensive since they don’t have an extremely long shelf life. You’ve probably realized that super glue doesn’t last for long if you don’t close the lid tightly.

This is simply due to the fact that it was exposed to air moisture. You should therefore store these types of adhesives in a dry place and close their lids tightly.

Hot Melt Adhesives

Hot melt adhesives (HMA) are thermoplastic in a sticky form that liquefies when heated. When applied to 2 surfaces, these types adhere once they cool. They’re usually colorless, translucent, amber, tan, or clear.

However, you can find HMAs in colored forms too. Hot-melt glues are particularly popular in bonding foam mattresses.

Moreover, these adhesives are mostly applied using a spray, unless its solid share reduces by about 75% to allow the liquid state. 100% solid HMAs are used to bond foam to different substrates without including any solvents.

Additionally, they cure fast, allow efficient methods of applications, and save both money and time. The only limitation with these adhesives is that they tend to make noises when they’re moved or bent.

Solvent-Based Adhesives

Solvents-based glues form strong bonds on foam using a solvent known as a carrying agent. These types of glues are set after evaporation of the solvent. They are commonly used in bonding foam to foam or to other materials.

Additionally, they can be applied by spraying, beads & dots, or roll coating.

These types of glue are the best where the strength of the bond is required. However, these adhesives are claimed to be dangerous to the environment.


Things to Consider Before Buying Foam Glue

When purchasing the best glue for craft foam sheets, there’re certain factors you should put into consideration. These factors will help you determine the capabilities of a certain brand to meet your needs completely. And they include;

Bonding and Curing Speed

First and foremost, you should consider the speed at which the glue you’re intending to buy bonds. However, you can increase the speed of bonding by using the product in a place with high humidity.

On the other hand, knowing the curing speed of an adhesive helps you optimize the benefits offered by the brand. The working/opening time of the adhesive is the maximum amount of time taken by the product to bind the materials.

Once the open time is completed, the adhesive will have completed the chemical reaction, thus creating the strongest bond. Therefore, this will help you to determine the maximum bond strength offered by the glue.

Ease of Use and Dispensing

Some foam glues like epoxy adhesives involve 2 parts that should be mixed. In this case, you should know how to get accurate mix combinations to make the process simpler.

Additionally, you should consider how easy it is to dispense the adhesive from the bottle or can onto the surface. Most brands come in a patented applicator which enhances precise application, thus enabling you to apply glue accurately.

Curing Process

Some glue requires thermal curing which is fast and takes place at room temperature. But, the heat might damage the surfaces being bonded with the adhesive.

On the other hand, UV curing is done on some glues, but only when the adhesive contains UV-transmitting substrates. However, of these 2 methods, the results of thermal curing are relatively better and it’s faster.

Performance and Finish Appearance

The performance of an adhesive varies depending on various features like bond strength and stress consistency. If an adhesive requires curing, one should have the ability to identify the specific temperature required for effective processing.

Moreover, the best foam glue should leave a soft, clean, and clear surface after each application. This enables you to maintain an aesthetic value for the bonded materials.
