You probably know that epoxy is a tough material, but how much heat can it really withstand? You might be surprised to learn that epoxy is affected by heat and can even break at certain temperatures.
It may surprise you, even more, to find out how high those temperatures are! So what exactly happens when you start cooking with your epoxy kitchen countertops or baking on them?
There have been cases where people have accidentally melted their own countertops due to improper use of the materials in their homes. Let’s explore some of these scenarios and find out what we can do about them.
What happens if epoxy gets too hot?
If you get your epoxy into the 180°F (82°C) range, depending on what kind of epoxy you’re using, there’s a chance that it’ll become brittle or even gooey.
If your epoxy gets too hot, it can also get soft and sticky. If that happens, you might find yourself with a runny or stringy mess on your hands!
Anytime you heat up an epoxy resin until it becomes runny and/or stringy is not a good thing because this usually indicates that something has gone wrong with the chemistry of your project.

Is epoxy affected by heat?
Epoxy is affected by heat, but this doesn’t mean it will melt or break down when exposed to high temperatures.
The epoxy used in our tape has been designed to withstand a wide range of temperatures – from room temperature up to 100ºC (212ºF), which is the same as boiling water. However, epoxy can get too hot if exposed for too long or at too high a temperature.
If an area of epoxy gets too hot from being exposed to direct sunlight or from being held in your hand without gloves on, your skin can burn and blister—even if you’re wearing gloves! If this happens with E6000 adhesive, you should clean off any residue immediately and flush the area with cool water for several minutes until there are no more blisters forming.
After about 10 minutes, treat any remaining open wounds with medical tape or gauze dipped in disinfectant before covering them with an antibiotic ointment containing zinc oxide powder—this will help prevent infection while healing occurs over time (about two weeks).
What temperature does epoxy break?
Epoxy is a relatively strong material, but it doesn’t take much heat to start breaking the bonds between its molecules.
In general, epoxy starts to break down when it reaches temperatures above 230°F (110°C). At this point, you’ll see the resin start to lose its shape and become more malleable.
At 350°F (180°C), you’ll start seeing small cracks form in your epoxy. These small cracks will grow as the temperature increases even further—at 400°F (204°C), they’ll be large enough for you to see with your naked eye!
As you can imagine, this is definitely not good news if your project needs an unbreakable bond at high temperatures because once those bonds are broken…they’re gone for good!
Can curing epoxy start a fire?
The short answer is yes, curing epoxy can start a fire. Epoxy is flammable, meaning that it can burn. And when you’re using a torch to cure your epoxy and it’s in contact with other materials like wood or metal, the risk of fire increases.
That doesn’t mean you shouldn’t use epoxy though! It just means you need to take some common-sense precautions while using it so that things don’t get out of hand. For example:
- Don’t smoke while working with curing epoxy (or any other flammable substance).
- Don’t light up candles nearby if there are open containers of curing materials lying around.
- Keep the area clear of clutter and anything that could catch fire easily like paper towels or rags (these can ignite from heat). You might want to consider wearing gloves too since they’ll keep your hands from getting burned if something goes wrong!
What is the most heat resistant epoxy?
Epoxy is a polymer. Polymers are good insulators and resistant to heat, cold, water and chemicals. They are also good at resisting radiation.
Epoxy is used in electrical insulation because it can withstand high temperatures without failing like other forms of plastic would.
It has also been used to make fiberglass kayaks and canoes that are both lightweight and strong enough for whitewater rafting trips.
Can you put a hot pan on epoxy?
It’s not a good idea to put a hot pan on anything. This includes epoxy, and it also includes your countertop, table or floor.
But you really don’t want to do this in the first place! It will definitely leave some damage—and possibly ruin your expensive new countertop!
Is epoxy flammable when dry?
Epoxy is not flammable, but it can be ignited. In other words, although epoxy does not have a flame and cannot catch fire on its own, it will combust if exposed to an open flame or other source of ignition.
Does epoxy melt in boiling water?
The short answer is no, epoxy does not melt in boiling water. However, it can be affected by heat and fire.
Epoxy is a thermoset polymer, which means that it’s an organic polymer that becomes permanently crosslinked when heated or subjected to other high-energy processes (like UV radiation).
This also means that epoxy cannot be melted like thermoplastics like polyethylene and polypropylene can be melted down and remolded into new shapes.
That said, if you put an uncured epoxy resin on a hot surface like your stovetop (or even just in the oven), it may emit harmful chemicals such as formaldehyde gas or carbon monoxide gas which could cause problems for anyone exposed to them over time—especially young children who have not yet developed their lungs’ resistance against harmful toxins! So make sure your work area is well-ventilated when using curing agents like hexamethyldisilazane or methyl chloride iodide—or better yet: use them outdoors where there’s plenty of air circulation!
Conclusion
So, to sum up: epoxy is a tough material that can withstand the heat of a barbecue or a hot pan. However, there are some caveats to keep in mind.
It’s best not to put any objects directly on top of the epoxy when it’s curing—instead use something like parchment paper between the two surfaces so they don’t touch each other at all (even though they will still adhere through the air).
And never try using your oven as an incubator for curing epoxy!
