To properly bond two surfaces together, super glue requires a specific temperature range to work effectively. So, let’s take a look at the ranges for the other popular brands as well as the importance of the application temperatures when using super glue.
Contents showWhen using super glue in certain conditions, it’s good to know what the temperature range is for the specific one you are using.
The operating temperature range means that the glue will not break down when exposed to temperatures within this range.
For instance, Original Super Glue has an operating temperature range of -65° to 180° F. If temperatures fall below -65° F or exceed 180° F, the bond will eventually fail.
The application temperature of super glue is the lowest temperature at which the glue can be applied.
This means that the temperature of your working environment, materials, as well as the super glue all have to be above this range to dry properly.
Super glue can be used in cold weather, but minimum application temperatures vary from brand to brand.
Keep in mind that most super glues need to be applied at temperatures above 45°F -50°F to bond properly.
Once the super glue has fully cured, it can withstand temperatures ranging from -65°F to 220°F. Check the brand’s instructions to ensure the temperature range will be suitable for your workspace.
Super glue can be used in hot weather. Just as it is the case with cold weather described above, temperature ranges vary from manufacturer to manufacturer as well.
Heat-resistant super glue is also a type of instant adhesive that is designed to resist high temperatures.
Household super glues made with ethyl cyanoacrylates can handle temperatures up to 180° F. So up to this point, you can call super glue heat resistant. If exposed to temperatures above the maximum limit of 180° F, the bond will begin to deteriorate and fail.
Super glue formulated with methyl cyanoacrylates can handle temperatures up to 195° F, and specialty allyl cyanoacrylates can typically resist temperatures up to 480° F.
Common household super glues, such as Gorilla Super Glue, Original Super Glue, and Krazy Glue, are all made with ethyl cyanoacrylates. These can handle temperatures up to 180°F, with Gorilla Super Glue resistant up to 220° F. Don’t forget though: When exposed to temperatures above the maximum range, the super glue will weaken and break down.
No, super glue does not melt in extreme heat. If exposed to temperatures above the maximum limit, it will begin to crystalize and eventually fail.
Yes, in its liquid state, super glue is 100% flammable! No matter if it’s Gorilla Super Glue, Krazy Glue or Loctite Super glue, they all burn while liquid. We even have provided a picture that proves it:
Once dry however, super glue is not flammable.
From freezing temperatures to extreme heat, the performance of super glue can be affected, and it is essential to choose the right type of adhesive for the intended use. While some super glue formulas are designed for specific temperature ranges, others can perform well in a wide range of temperatures.
By following the manufacturer’s instructions and taking appropriate precautions, you can make sure that super glue bonds effectively in any temperature range, providing a reliable and durable hold.
I love playing pickleball and spending time with my family. I'm married and we have two kids, a son, and a daughter. I work on my website, GlueSchool.com, in my spare time. This website is dedicated to all things glue!
