Epoxy resin is a popular and versatile adhesive. Epoxy can be used to bond metal, wood, concrete, ceramic, and more. It’s also one of the best adhesives for outdoor projects because it’s waterproof and resistant to UV rays.
When working with epoxy you may wonder: Does cold weather affect epoxy resin? In this article, we’ll answer that question by exploring each aspect of cold weather use for epoxy resin.
Can you freeze cured epoxy resin?
You can freeze cured epoxy resin. I have done it numerous times and my projects have turned out just fine.
To freeze epoxy, simply place the bottle of resin in a ziplock bag, seal it up tight, and put it in your freezer (or fridge). This will keep your epoxy from getting too cold while you are working with it.
If left at room temperature, the outside will get too cold and turn into an unusable goo that won’t flow through your syringe. Once thawed out again, however, the material will be normal once again!

At what temperature does epoxy freeze?
Epoxy resin freezes at -10 degrees Celsius (14 degrees Fahrenheit), which is the temperature at which it becomes a solid. This means that you can use epoxy resin as an adhesive and as glue if your project has been frozen or left at low temperatures for any length of time.
Can epoxy be stored in the cold?
Epoxy is a thermoset, which means that when it cures (hardens), the reaction can’t be reversed. This is different from an adhesive such as hot glue where you can reheat it and use it again.
Epoxy is also a resin, hardener, and chemical. It’s often used as glue or plastic in construction materials like fiberglass boat hulls or concrete building blocks because of its strength and durability after curing.
You may have heard of “Bondo,” which is a type of epoxy used to seal cracks in cars’ bodywork before painting them to match the color scheme again!
How do you store leftover epoxy?
Epoxy, if stored properly, will last a long time. The best way to store your epoxy is in a cool, dry place away from UV light and away from heat. If you need to store it for more than a few months, keep it at temperatures below 80 degrees F (26 C).
If you want to make sure that your leftover epoxy lasts as long as possible without having to repurchase more when you run out, follow these guidelines:
- Keep the container in its original packaging with its lid sealed tightly.
- Store the container in an area where it’s not exposed to direct sunlight and cannot absorb moisture. Avoid storing containers of epoxy near sinks or bathrooms where there is a risk of getting wet accidentally.
- Don’t leave any containers open or unsealed for long periods of time—this will increase their rate of decay over time due to exposure from air circulation around them until they eventually become unusable after prolonged exposure like this!
What happens if you put resin in the freezer?
That depends on the temperature and type of epoxy you’re using. Some high-performance epoxies can’t be frozen, but most can. If your project must be done in cold weather, keep these tips in mind:
- Make sure that the resin is mixed thoroughly before applying it to a surface or object. Thorough mixing ensures that all of the ingredients are distributed evenly throughout the mixture, which will prevent clumps from forming during application and curing stages.
- If you’ve added any fillers or hardeners to your mixture (e.g., tung oil), make sure they’re well blended into the rest of your materials before applying them, or else they may end up clumping together when exposed to cold temperatures after being applied and cured with catalysts such as UV light sources like black lights or sun exposure depending on what kind of resin we’re talking about here).
What happens to resin when it freezes?
Yes, you can freeze epoxy. Epoxy resin is a thermosetting plastic that hardens when it cools. This means it will not mix together with the hardener (the catalyst) until it reaches a certain temperature and then begins to set quickly.
If you store epoxy in a freezer, though, this process will not happen at all: any epoxy that remains frozen will remain in its liquid state indefinitely, never setting or curing even after being thawed out and returned to room temperature.
The same thing applies when storing finished products made with epoxy resins—they too should be kept away from freezing temperatures; if they are stored in cold storage facilities and later thawed out, they may never cure properly again!
Can you put epoxy in the fridge?
You cannot put epoxy in the fridge, but there is nothing wrong with doing so. It will not hurt the epoxy or change its properties, and will not make it last longer or cure faster.
You should be careful not to get any ice crystals in your mixture as they can damage your workpiece (along with other issues), but you don’t need to worry about temperature changes causing any problems.
Does cold weather affect epoxy resin?
When it comes to cold weather, epoxy resin can be affected by the following:
- Becoming brittle.
- Becoming cloudy.
- Having a shorter shelf life.
Conclusion
Epoxy resin is a durable material that can withstand temperatures as low as -40 degrees Celsius (-40 F) when properly stored and handled. If you have any leftover epoxy resin, there are several ways to store it so that it doesn’t freeze in the winter months.
You can put your epoxy in the refrigerator or freezer if necessary, but be aware that doing so risks changing its chemical composition over time.
