What is the shelf life of ArtResin?

ArtResin is a two-part epoxy resin that, when mixed together and poured over a substrate, cures to a hard high-gloss finish.

ArtResin has a shelf life of approximately 7 months in its original container before it starts to become cloudy or discolored or the odor becomes unpleasant. If you have any doubts about your product’s freshness, always test before use.

When ArtResin is not being used, keep it in a cool dark place away from direct sunlight and heat sources (like radiators). The more extreme the temperature fluctuations are for your resin, the quicker its shelf life will be diminished.

As ArtResin ages, the two parts start to degrade and this degradation results in resin becoming increasingly cloudy and then eventually turning yellow as it becomes unusable.

Badly degraded epoxy resin can also develop an unpleasant odor (think nail polish remover) which will let you know that it’s time to throw that bottle out!

Proper storage can help extend the shelf life of your ArtResin because when the two parts are kept separate until the point of mixing, they don’t age as quickly as they do when exposed to oxygen after mixing.

Does araldite go out of date?

Araldite is the brand name of a two-part epoxy resin used in various fixing jobs at home or in industry. It is used to glue glass, wood, ceramics, perspex, concrete, metals, and some plastics.

The shelf life of Araldite depends on how it was stored. The resin will remain viable if kept in its original packaging and stored under normal conditions.

Once opened and mixed with the curing agent, however, the mixture should be used up within the hour as it will begin to harden by then.

Does epoxy have an expiration date?

Think of epoxy like you think of milk; it goes bad if it’s left out too long with the cap off. Ideally, you don’t want to use anything after its shelf life has expired, but if you store it properly and keep an eye on the freshness date, it can last for a really long time.

Epoxy resins have a shelf life of 12 months from the date of manufacture. If stored in its original container in a cool environment (below 85F or 30C), away from direct sunlight, and sealed when not in use, our resin will last much longer than that—sometimes several years.

How do you know if epoxy is expired?

While there are no expiration dates on our products, they will last a very long time if stored properly.

If you are uncertain as to whether or not your epoxy has gone bad and want to test it out before using it for your project, please see our blog post Can You Test Epoxy Resin That Has Gone Bad? for a few easy tests you can do at home.

If your epoxy is expired or has gone bad, it will not cure and will stay sticky (or stringy) when applied. It may also not mix properly when combined with the ArtResin Part B resin or may have an off-color in certain spots on the surface of the resin.

Can you use out of date resin?

The shelf life of ArtResin ™ epoxy resin is one year from the date of purchase. However, there are a few factors that can affect your resin’s shelf life:

  • The ideal storage temperature for ArtResin is 75 degrees Fahrenheit (24 C). If you consistently store your resin at room temperature (68 F or 20 C) or higher, the working time and cure time will be shortened by 5% to 7%. Remember that high temperatures reduce the shelf life of uncured resin as well.
  • Once opened, it should be used within 6 months if properly resealed and stored in a cool, dry area.

What happens when you use out of date epoxy? You’ll have less time to work with it, which means you won’t be able to do as much as you might normally do with fresh product.

Generally speaking though, there’s no harm in using older epoxy resin – but first, why not give it a good stir just to see how fluid it is? If its consistency has changed significantly – meaning if it’s become cloudy and thickened up considerably – then ESPECIALLY don’t use it! This would be an indicator that the hardener has started to separate from the resin.

Instead of using it, get rid of it as soon as possible by pouring both bottles into a disposable container and allowing 48 hours for curing. After that point dispose of it according to your municipality’s hazardous waste regulations.

How do I get rid of old araldite?

  • Use super glue remover.
  • Use acetone, which is the same chemical in nail polish remover.
  • Use a craft knife to scrape off the old Araldite.
  • Use a razor blade to scrape off the old Araldite.

How do you unstick araldite?

So now you’ve got something stuck together and you need to unstick it. What do you do? While we definitely don’t recommend using ArtResin to glue things together, we know it’s happened and that some people don’t realize that the epoxy is permanent.

If you’re trying to unstick something glued with ArtResin, here are some options:

  • Apply heat to the joint – This expands the plastic and should help break the bond. Be careful not to melt or burn your piece, though! If you’re going to use heat, be sure to use a low heat source such as a heat gun (not a torch).
  • Try breaking the bond with a hammer – By hitting one side of the glue joint with a hammer, you may be able to break away one of the pieces from the other. Be sure not to damage your piece!
  • Use cold chisels or a hacksaw blade – Gently tapping your chisel or hacksaw into where two surfaces meet will help loosen them if they’re stuck by glue. This won’t work on all materials but it’s worth trying!
  • Use solvents or acids – Solvents like acetone can often dissolve or weaken polyurethane adhesives like Araldite so their hold is less strong… but they can also soften up plastics too which means they could damage your piece so be very careful if using this method!! (we would NOT recommend this)

Is araldite the strongest glue?

The Araldite family of epoxy adhesives was first invented in the 1940s and has been used in thousands of projects ever since.

They are a two-part epoxy adhesive meaning they are comprised of a resin and hardener that when combined, cure to form a strong bond.

This is an extremely versatile type of glue as it can bond virtually anything to anything! These adhesives have become popular for craft projects as they provide an exceptionally strong bond between surfaces and materials such as wood, metal, stone, ceramics, glass, concrete or china.

The Araldite range also includes a wide variety of formulas that offer different benefits depending on the project or material being bonded.

In fact, their strength has earned them the nickname “the strongest glue” which is how many people arrive here at ArtResin’s website because every Google search for “araldite” brings up our blog post about why this product shouldn’t be used with ArtResin (TIP: Always scroll past the ads!).

So we thought it would be helpful to offer you some facts about Araldite products so you can make informed decisions about your next project!

How long does unopened epoxy last?

The answer depends on storage conditions. At room temperature, unopened epoxy resin has an extremely long shelf life it will last for decades.

Once you open your ArtResin, the clock starts ticking and the product will no longer last forever since oxygen can now enter the bottle and interact with the resin.

Just as many foods go bad when they’re exposed to air, epoxy resin can begin to break down when exposed to air as well.

This is why we recommend that you only mix what you are going to use right away – in other words, mix small batches of epoxy resin at a time so that minimal oxygen enters the bottle and only what’s needed is used (thereby reducing waste).

This way your ArtResin should remain viable for up to 2 years after opening. If unused epoxy begins to discolor or separate over time, it has gone off and should not be used.


So, to quickly recap:

  • ArtResin’s shelf life is 3 years on the shelf, 18 months after opening
  • It has a 1:1 mixing ratio that makes it easy to use
  • Its FDA-approved ingredients are non-toxic, making ArtResin safe for home use
