can 2 part epoxy freeze?

Epoxy resin is a two-part system that needs to be mixed together before you can use it. This means that you’ll have leftover epoxy resin sitting around your house, which is something that many people are wondering about.

So what happens if you leave your epoxy resin in the garage and it freezes? Well, let’s find out!

Can you freeze cured epoxy resin?

You can freeze cured epoxy resin and it will be fine. The curing process just stops when it reaches that temperature, and then you can continue working with the material when it thaws out.

How long this takes depends on the size of your piece and what you’ve used to make it (for example, would you consider an outdoor sculpture to be a “piece” or an “object?”) But if you’re asking about ice sculptures or other things made out of epoxied material, they will probably take longer than 24 hours to thaw back out.

The best way to store your frozen epoxied pieces is in a freezer bag that’s been labeled with contents and date/time so that no one accidentally decides they want some cheese dip for lunch until next year.

At what temperature does epoxy freeze?

The most common question people ask is if epoxy freezes. The answer is yes, but not always. There are many factors that will determine whether or not your 2 part epoxy will freeze.

These factors include the temperature of the resin, hardener, and ambient temperature when you mix them together; the ratio of each component; air pressure around you; and whether or not any protective elements like catalyst were added to your mix. Here’s how it works:

Can epoxy be stored in the cold?

It’s important to remember that epoxy resin is not affected by cold temperatures. In fact, it can be stored in a cool, dry place without freezing or damaging the product. It is still best to store your epoxy in a refrigerator or freezer if you have one available.

The colder temperature will keep your epoxy fresh for longer than if left at room temperature and humidity levels tend to be lower inside refrigerators and freezers than outside them so there’s less chance of condensation forming on the bottle or container that could damage its contents over time.

The best place to store your bottles of unused epoxy is in an upright position with its lid tightly closed so that no dust or moisture gets inside of them while also making sure there isn’t any air trapped inside either since this may cause bubbles when mixing later on down the line!

If using acetone-based products like MEKP instead then make sure they are stored upside down away from other chemicals because even though both types are solvent-based solutions they still react differently due to their composition which means storing them incorrectly could result in unwanted reactions happening between ingredients later on down until using again when mixed together correctly (this would result in clumping instead).

How do you store leftover epoxy?

  • Store the epoxy in a dry place.
  • Store the epoxy in a sealed container.
  • Store the epoxy in a cool place; if you have to store it for longer than 12 months, keep it at room temperature (65–75° F).
  • Keep the epoxy out of direct sunlight and away from heat sources like radiators or stoves.

What happens if you put resin in the freezer?

If you put resin in the freezer, it will harden. This is because the curing process of epoxy is halted by cold temperatures. The chemical bonds that form during curing are inhibited, so very little will actually happen to your resin or your part.

If you freeze your epoxy, it will not be cured and therefore won’t have any strength. The resin may be usable again if you warm it back up and allow it to cure properly—but even then there are limits as to how much stress can be applied before failure occurs!

What happens to resin when it freezes?

Epoxy resins will not freeze, but the solvents in the hardener can. If your epoxy has frozen and you need to thaw it out, place the container with both parts in a bowl of hot water for at least 30 minutes. If your epoxy has hardened and you notice a change in color or viscosity (thickness), it’s time to get rid of it.

If you do not want your resin or hardener freezing during winter months, consider storing them inside a refrigerator or freezer that stays at room temperature when turned off (such as an unplugged fridge).

Does cold weather affect epoxy resin?

  • What is cold weather? Cold weather is a temperature below 50 degrees (F), which means it can be in the ’30s or ’40s.
  • Does cold weather affect epoxy? Yes, depending on the type of epoxy you have and how you use it.
  • How do you use epoxy in cold weather? When working with an epoxy resin, make sure to keep your hands warm while working on the project so that when applying resin, the glue won’t get too sticky due to your body heat and stick itself onto your skin instead of where it should go. You might also want to wear gloves when handling this product for long periods of time as well!
  • How do I store my 2 part epoxy in cold conditions? You can either keep them together at room temperature or place them in a refrigerator/freezer until ready for use again (some manufacturers recommend keeping them refrigerated). If storing them at room temperature, make sure all caps are tightly sealed before putting them away so no moisture gets inside; otherwise, molding may occur later down the road which will ruin any containers stored inside this way for extended periods without proper care taken beforehand.”

Can I use a hairdryer to dry epoxy?

Hairdryers are not a good way to dry epoxy. A hairdryer will make it take longer for the epoxy to fully cure and can also cause bubbles in your finished product, which is not what you want.

If you’re using a high heat setting on your hairdryer and still get bubbles, try using a blow dryer instead.


I hope that you now have a better understanding of how epoxy freezes and thaws. The answer to the question “can 2 part epoxy freeze” is yes, but only under certain circumstances.

If your resin freezes while it’s curing or if it’s stored at too low of a temperature, then there may be some issues with its performance.

There are also some tips that can help prevent this from happening in the first place so make sure to read them before applying any two-part epoxy coating onto your project!
