How much does epoxy resin last?
If the bottles remain unopened, ArtResin has a shelf life of 12 months from the date of manufacture. Once the bottles have been opened, however, the shelf life is 6 months from the date of manufacture.
Does epoxy resin break easily?
Epoxy is very resistant to wear, cracking, peeling, corrosion and damage from chemical and environmental degradation. Once cured, epoxy is moisture resistant.
Does epoxy degrade?
Epoxy resins have a wide range of applications, including in corrosion protection of metals, electronics, structural adhesives, and composites. The consumption of epoxy resins is predicted to keep growing in the coming years. Unfortunately, thermoset resins cannot be recycled, and are typically not biodegradable.
Epoxy shelf life can last many years when resin and hardener are properly stored at room temperature and in closed containers to prevent contamination. Those who have used polyester resins know that its shelf life is only about six months before it turns to a useless jelly-like substance.
What is this? Resin does not melt in the sun; this is due to the chemical compound found in resin.
As long as you pour in 1/8" layers, you can go as thick as you like. The reason we recommend this thickness is two-fold: first, it allows the bubbles to escape properly, and second, it avoids any excessive overheating of the resin. So for best results always pour in a 1/8" layer, and you're good to go!
They show comparatively low cure shrinkage. Cured epoxies are brittle with poor resistance to crack initiation and growth. Their mechanical properties, in particular toughness, can be modified by incorporating a rubbery phase into the resin matrix.
Keep your workspace, resin and tools at standard room temperature: ideal conditions are 75F/24C - 85F/30C and should stay stable for the first 24 hours. Ideal humidity is below 50% however you can work in conditions less than 80% humidity.
While WEST SYSTEM® epoxy has a long shelf life, age will eventually affect its handling characteristics and cured strength. When stored for very long periods, hardeners may turn darker (reddish to purple), become thicker and give off more odor. 105 Resin may lose some clarity and also become slightly thicker.
What happens if you use expired ArtResin? Even if you were to use ArtResin beyond its shelf life, the resin and hardener will still react and cure as expected.
Yes. All of the resins I have worked with are pre-promoted and have a six month shelf life. I have been able to extend that a couple of months by keeping the resin in a cool place. I keep mine in the basement which maintains a steady fifty-eight degrees.
Tests on laboratory animals showed that older epoxy resins caused skin cancer. It is, most likely, due to epichlorohydrin, which probably causes cancer in humans as well. However, newer epoxy resins contain less epichlorohydrin, so they don't cause cancer in animals.
It is recommended that you keep mixed epoxy stored at around 40°F for no more than a few days. Once you reheat the epoxy, the curing process can resume.
So, in short yes: Resin parts can be over cured if exposed to UV light for too long. The light coming from a UV curing chamber is much stronger than the effect that sunlight has on the resin prints, and leaving them overnight will already show some signs of degradation.
The layer is too thick Each epoxy resin system has a “safe” pour depth at room temperature. If you exceed that depth the transfer of heat becomes problematic. If exceeded as the chemical reaction “kicks off” the amount of thermal mass exceeds the thermal transfer rate generating excessive heat.
If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. You can pour the next layer after the previous pour has gone through its heat cycle, which is usually around 24 hours.
Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.
With proper storage, resin and hardeners should remain usable for up to six months after opening.
Epoxy will not crack in freezing temperatures. The effects of freezing weather on epoxy only reduce its ability to cure properly. With low-quality epoxy, coating projects may not result as planned.
Most epoxy systems will shrink in a range of 1-5% in volume once fully cured. You will find that in most applications, this shrinkage is virtually undetectable.
And now, ArtResin has been recognized by the American Society for Testing and Materials (ASTM) as meeting safety standard D-4236: Safe for Home Use. Comparatively, most epoxy resin products on the market are classified as a hazardous material.
However. It still doesn't make sense to put it in an environment full of UV rays it makes it much harder for that UV stabilization to do a good job. Keep it inside and keep it clear.
We know that most epoxies perform well or, at least reach a higher percentage of their potential physical properties, at temperatures of 60°F and above. Some resin/hardener combinations are formulated to cure in temperatures as low as 35°F.
