Things You Need to Know to Choose the Right Adhesive

When it comes to making the right decision, regardless of what it may be about, it is wise to always gather as much information as you can. This is especially true in the case of adhesives, where even one tiny detail can change the entire situation. When choosing the right adhesive, there is no such thing as looking into too much detail, so for starters, make sure you have the answers to the following questions.

What substrates are you bonding?

When trying to find the right adhesive, it is crucial that you know a little about the materials you will be attempting to bond. Every substrate has very different properties and will react in different ways depending on the substrate with which you are trying to bond it. So, before you start researching your adhesive, do a little research into the substrates you are hoping to bond. Don’t forget to take into account if the surface has been painted, lacquered or treated in any way, as this can have a big impact on how well adhesives will be able to effectively create a bond.

What stress will the bond experience?

This is another vital consideration when it comes to choosing the right adhesive, because if you plan on putting your newly established bond under extra stress, you are going to need to use one of high strength. Consider the peel force, tensile force or even compression that the bond may have to handle, and choose your adhesive accordingly.

What will the environmental conditions be like?

This is an extremely important consideration when choosing an adhesive, as the right choice will be vastly different depending on the environmental conditions the bond will need to be able to withstand. If the bond won’t have to deal with anything more than moderate weather conditions, you have far more choices, but if you need something that can deal with extreme cold or extreme heat, you will need a far more specialised adhesive.


Think about how you plan on using the adhesive and how quick you will need for it to be able to bond, as this will make a big difference to your choice. Fast-acting adhesives can significantly speed up production, but are unforgiving when it comes to mistakes, so think about how fast you actually need your processes to be.

Will it be exposed to chemicals?

Chemicals can have a deteriorating effect on other surfaces and substances, so if there is any chance that the bond will be exposed to any sort of chemicals, look into what they are and establish the amount with which your bond will come into contact. There will likely be several adhesive options able to deal with exposure to the chemical.

What have you tried and what happened?

If you have tried and failed in past attempts to bond these same two substrates together, think back to what happened with each of your attempts, and relay this information to your adhesives expert when considering your choices. An adhesive failure will often contain telltale signs that point to other options that may work, so be sure that you learn from your failed attempts.
