This is not recommended if you’re using a water-based product, such as epoxy resin. Water-based products will become more viscous when they are frozen.
This can make it harder to work with and may not cure properly when applied. Some epoxy resins are suitable for use in cold temperatures but only if they are mixed at the right ratio and used within a certain time frame (which their packaging will tell you).

Can I freeze epoxy resin?
Epoxy resin is a two-part liquid that you mix together to make a bonding resin. The main ingredients in epoxy resin are polymers and solvents.
Because of the solvents, they can be used to bond dissimilar materials, like wood or metal. Solvents also allow you to paint over epoxy without worrying about diluting it or waiting for the solvent to evaporate before painting over it.
The fact that epoxy contains solvents means that if you freeze it, those solvents will expand and break your container or any brushes you use with it. They also won’t cure while they’re frozen because they need heat in order to solidify into a hard surface.
What happens if epoxy gets too cold?
You might be wondering, “Can epoxy freeze?” The answer is yes! Epoxy resin can be frozen and then thawed again. How do you tell if your epoxy is frozen? It’s easy to tell by the texture—if it feels like ice cream that has partially melted, then it’s probably good as new.
What if you want to prevent your epoxy from freezing in the future? If my freezer ever gets too cold (it hasn’t yet), I don’t think this would be an issue for me because I use a small ceramic mixing bowl instead of a larger plastic one which would hold more heat.
But if this does happen and all attempts at preventing freezing have failed, there are several methods for thawing frozen epoxy:
- Use warm water on top of the container—don’t put it in boiling water or immerse fully submerged
- Put in the microwave until liquid
- Warm-up with a heat lamp
Can you put cured resin in the freezer?
You can put resin in the freezer without it losing any of its properties. It will not crack or shrink, and it will not lose any strength.
In fact, most epoxies are extremely stable at low temperatures and won’t freeze until they reach -100 degrees F (-73 C).
In addition to being resistant to freezing, epoxy resins also have excellent chemical resistance. They can withstand exposure to many acids, bases, salts, and other chemicals that would otherwise damage other materials.
This makes them ideal for industrial applications where they may come into contact with harsh chemicals or liquids that might damage other types of adhesive products
Does freezing resin make it cure faster?
No, freezing does not make it cure faster. Epoxy resin will already cure at room temperature and there is no way to speed up the process by freezing it.
If you want to speed up the curing process, you can use a heat gun instead of waiting for epoxy resin or polyester resin to dry naturally in an ambient environment.
Does epoxy crack in the cold?
Can you put epoxy resin in the freezer? The answer is yes, you can. But if you’re hoping that freezing your resin is going to make it crack more, then think again.
Epoxy will not break in the cold, no matter how thin it is or how thick it has been mixed. However, if your mix contains too much of one component (for example, hardener or resin) and not enough of the other component (for example, epoxy resin), then this could cause it to crack as soon as it comes out of the fridge.
So does that mean there’s no harm in keeping your epoxy for a short period of time at room temperature? Well… yes and no!
If you know exactly what type of project you’ll be working on next—and can prepare ahead—then go ahead and store your leftovers at room temperature until then; otherwise just stick them in the fridge after each use so they don’t go bad before then (or worse: get contaminated).
Will resin set in cold weather?
Can we keep resin in fridge?
While it is not recommended to keep resin in the fridge, it will not cure faster or freeze if you do. It is also not any safer for you to keep your resin in the fridge or freezer than it would be to store it at room temperature.
What temperature does epoxy freeze at?
The temperature at which epoxy resin freezes is -20 degrees Celsius (or -4 degrees Fahrenheit). This is the same as what it takes for water to freeze, so if you have a jar of epoxy resin in your freezer, there’s a good chance it would be frozen solid if you were to remove it and set it out on your countertop.
You should know:
- Epoxy resin will not freeze at room temperature. It needs something colder than that—like, say, your fridge or freezer—to do its thing.
- Epoxy resin won’t freeze in your fridge or freezer either (unless you’re talking about a very large container). These appliances are designed to keep food cold but not frozen solid; this means their temperatures fluctuate between 50 and 40 degrees Fahrenheit on average.
You can use epoxy resin in the freezer. It’s a great way to create a concrete block out of ice, but keep in mind that the shelf life is less than 24 hours due to its high water content.
