There are a few reasons why epoxy resin might be flexible. One reason is that the curing agent might not have had enough time to react with the resin.
If this is the case, you can try stirring the mixture more vigorously or using a higher-temperature curing agent.
Another possibility is that there wasn’t enough catalyst used in the mixture. You can try adding more catalysts to see if that solves the problem.
Finally, it’s possible that your epoxy resin was stored in a warm environment for too long. In this case, you might need to refrigerate it before use.
How do you fix soft resin?
There are a few things you can do to help fix a soft resin. One is to add some reinforcement fibers, like glass or carbon fiber.
This will make the resin stronger and less likely to deform.
Another option is to increase the ratio of hardener to resin. This will make the resin harder and less flexible.
Finally, if your project requires extreme flexibility, you can try using epoxy with a higher flex modulus.
Flex modulus is a measure of how much a material deforms when it’s stretched; the higher the flex modulus, the stiffer the material.
So, by choosing an epoxy with a high flex modulus, you can get more flexibility without sacrificing strength.

Why is my epoxy resin still soft?
One potential reason why your epoxy resin is still soft is that the curing process was not completed.
This can be caused by a variety of factors, such as improper mixing or insufficient curing time.
Be sure to check the manufacturer’s instructions carefully to make sure you are following all of the necessary steps for a successful cure.
If you have followed all of the guidelines and your epoxy resin is still too soft, it may be necessary to contact the supplier for assistance.
Is resin supposed to be bendy?
Many people who are new to resin ask this question. The answer is: it depends on the type of resin you are using.
There are two main types of resins- epoxy and polyester.
Epoxy resin is more flexible than polyester resin, but both can be bendy depending on how they are made.
Some resins are designed to be more flexible than others. For example, casting resins tend to be more flexible than flooring resins.
This is because casting resins need to conform to the surface they are being applied to, while flooring resins need to be tough and durable.
If you want your resin project to be bendy, then you should use epoxy resin.
How do you harden flexible resin?
First, you need to make sure that your resin is flexible. Most epoxies are only somewhat flexible, but not very bendable or stretchy like silicone.
However, there are some resins that can be made into a rubber-like compound for use in various products and projects where flexibility could come in handy. If you’re looking for the best way of how do I harden my resin?
Then this post will show exactly what needs doing step by step from beginning to end so it becomes nice and stiff again!
It doesn’t matter if it’s clear or opaque either – both types work just fine with these simple instructions on How To Make A Resin Mold For Jewelry Making With Easy Steps!
Why did my resin not harden?
The main reason for this is that the resin has not been mixed in with enough hardener.
The mixing of epoxy resins and hardeners must be done at a very specific ratio if you want to get an optimal cure.
There are many different formulas for epoxy resins, each needing its own ratios.
Because there are so many combinations it is important to follow the manufacturer’s recommendations regarding mix ratios because they will know exactly what works best with their product and how much catalyst needs to go into any given amount of resin.
How can I make my epoxy more flexible?
Most epoxies are not flexible. But epoxy is better than glue because you can use it to bond the same material or different materials, like metal and plastic.
It also bonds well with glass, wood, and ceramics.
Epoxy resin does have some limitations though: you cannot use it for bonding rubber or leather products; nor will it work on certain kinds of metals such as zinc-plated steel.
If you want your finished product to be strong but also flexible then there are some other options available that may suit your needs better!
What happens if you add too much hardener to epoxy?
The epoxy will become too hard and brittle to be useful. It may also cause the resin to cure too quickly, leading to uneven curing and potential problems with the finished product.
Be sure to follow the manufacturer’s recommended ratios for best results.
If you are unsure about how much hardener to use, start by adding a smaller amount and increase it gradually until you reach the desired level of hardness.
How do you harden tacky epoxy?
One way to harden tacky epoxy is to add a catalyst. Catalysts are chemicals that speed up the curing process of epoxy resins.
When adding a catalyst, always follow the manufacturer’s instructions.
How do I know if my resin is cured?
The resin is cured when it’s no longer sticky and it has a hard, glass-like finish. If you’re not sure if your resin is cured, try bending it.
If it bends easily, then the resin isn’t fully cured yet.
Allow the resin to cure for a few more hours or days until it becomes harder.
Is there a flexible epoxy?
There is no definitive answer to this question as it depends on the specific resin system and application.
However, in general, most epoxy resins are flexible to some degree.
This property can be beneficial in certain situations, such as when an object needs to withstand impact or vibration.
Conversely, if too much flexibility is desired, a softer polymer such as PVC may be a better option.
Can resin be used without hardener?
Yes, you can use resin without hardener however the cured product will not be as strong or durable.
We do not recommend using resin without hardener unless it is for a very small project.
