Epoxy resin is a popular product for DIY projects, but it can be tricky to use. There are many factors that affect how well epoxy will work, including temperature.
In this article, we’ll look at whether or not you should freeze epoxy and answer some common questions about whether your project will hold up in cold weather!
Can epoxy resin be frozen?
As a general rule, epoxy resin will not freeze. In fact, it will only partially freeze at temperatures as low as -40°F (-40°C). This means that you can store your epoxy in an unheated garage during the winter without having to worry about it freezing solid and exploding when you come back to use it in spring.
However, if your epoxy is in a sealed container and frozen solid while still sealed (as opposed to just being frozen), there’s a chance that when you open the container it could explode.
To minimize this risk: don’t store your epoxy resin in any kind of closed space where it might be exposed to extreme cold or heat; and don’t leave any caps off containers filled with liquids for extended periods of time—this could cause them to leak out onto surfaces like countertops or floors.

What happens to epoxy when it freezes?
Epoxy resin is a chemical compound that will not freeze. You may be thinking, “Epoxy resin? What’s that? I don’t know what you mean by ‘epoxy resin’! What are you talking about?!”
To which I would reply, “Don’t worry your pretty little head about it—I am just so excited to tell you that the epoxy in your joint lubricant will never freeze! It won’t even get cold!”
“What do you mean by ‘never’? How can I trust this?”
“I’m not sure if I should believe you.”
The most common epoxy resin is polyurethane-based, which means it will not freeze at room temperature. It may get soft or start to bubble as temperatures drop below freezing but will never freeze completely
What temp does epoxy freeze?
For epoxy resin, the freezing point is between -20 and -30°F. The higher the mass of the product, the slower it will freeze. For example, a one-gallon container of resin will take much longer to freeze than a quart jar because there’s more volume that has to be cooled down.
How do I save leftover epoxy resin?
You can save the unused portion of epoxy resin in an airtight container and store it in a warm place, away from UV light, humidity, and heat. Keep in mind that epoxy resins are sensitive to moisture; they will harden when they come into contact with water.
Does epoxy crack in the cold?
The short answer is yes, epoxy resin is sensitive to cold. Depending on the weather and temperatures, epoxy will crack if exposed to freezing conditions for too long.
Epoxy performs best from 50 degrees Fahrenheit up to 90 degrees Fahrenheit. If you plan on working outside in winter or keep your workshop at a low temperature, it is wise to use a slower curing epoxy with a lower viscosity that will reduce the risk of cracking during its cure time (see step 3).
Will freezer harden resin?
The answer is yes. Freezer hardening resin does work just as well as regular epoxy, but it’s important to remember that the curing process will still take place.
Removing your completed project from the freezer and allowing it to cure at room temperature is essential for a strong bond and durable finish.
As you know, epoxies are mixed with hardeners which help them cure faster when exposed to high temperatures. This means that freezing doesn’t change this part of the curing process at all; it’s just going to happen over a longer period of time!
The temperature in your freezer won’t effect how long it takes for your project to be ready for use either—it’ll still be good after 24 hours or so (longer if you want).
So what should I do once I’ve pulled out my project?
Can you put cured resin in the freezer?
You can put cured resin in the freezer, but it won’t cure. This means that when you take it out, you’ll have to wait for it to reach room temperature before using it.
If you want to store resin in the freezer, place a layer of plastic wrap between each layer of epoxy. This will keep your pieces from sticking together and make cleanup easier when you’re ready to use them again!
When thawing epoxy at room temperature, do so slowly so that bubbles won’t form. If by chance some bubbles do form on your piece, don’t worry; they’ll disappear once they’ve been worked into the surface of your project (and if they don’t disappear right away).
Will resin set in cold weather?
It depends on the temperature of your epoxy resin. If it’s below 50 degrees Fahrenheit, the reaction will slow down (but not stop).
The curing time can take anywhere from 24 hours to 72 hours depending on factors such as humidity, temperature and amount of catalyst used in the mixture.
If you’re working in a cold environment and need to speed up your cure time, there are a few things you can try:
- Keep everything warm by placing containers that contain epoxy resin in an oven preheated to about 140 degrees F. Be sure not to let anything overheat since this could ruin your project!
- Add more catalyst than usual into each container so that it reacts faster when heated up later on at higher temperatures;
Conclusion
So, can you freeze epoxy resin? Yes! The answer is that it depends on the type of epoxy you use and how cold it gets outside your freezer. You can use an ordinary household freezer or a commercial-grade one for this purpose.
