Top 8 Best Epoxy for Tumblers for 2021
There’s a lot to factor in when deciding on the best resin for tumblers. Everything from cost and cure time, to hardness and resistance to bubbles, go into deciding on a really good resin for making beautiful tumblers.
Personal preference is also a huge factor. It may take a couple of tries and some not quite amazing results before you settle on your favorite; however, sticking with some of the most popular, and highest rated resins is a good way to find your favorite.
This list includes the ones we feel are great options to include in your arts and crafts projects.
1.ArtResin Epoxy Resin – Clear – Non-Toxic 1 gal (3.78 L)
First on the list is this one from ArtResin that’s made by the artists for the artists – delivering crystal clear and high-gloss end results! The product is specifically made for crafts and arts. It is easy to use, non-toxic, and self-leveling.
The package comes with 0.5 gallons or 1.89 liters of resin and hardener each.
This epoxy resin is chemically engineered with Hindered Amine Light Stabilizer (HALS) for non-yellowing protection. These additives allow for long-lasting clarity.
It also has a UV stabilizer that works to protect the resultant product against loss of glossiness, cracking and chalking, as well as delamination. To some extent, it also works together with the HALS additive to prevent yellowing.
Furthermore, it is non-toxic when mixed as recommended by the manufacturer. The mixing ratio should always be 1:1. That means you can only mix 0.5 gallon of resin with 0.5 gallon of hardener.
For added safety of use, this resin has no volatile organic compounds and is non-flammable as well as BPA-free. Basically, the product was able to pass the FDA food-safe certification requirements. Once cured, the epoxy resin turns fully inert for safe food contact.
The safety of use does not stop there, and this resin conforms to ASTM D4236, which makes it appropriate for home use.
You do not have to worry about solvents and non-reactive diluents. There is no ingredient in it that turns airborne and becomes detrimental to health.
What’s more? ArtResin can tolerate a maximum temperature of 120 degrees Fahrenheit or 50 degrees Celsius.
It will be easier for you to work with it as it becomes more flexible at such temperatures. Depending on the number of layers you use, it can be cured in about 72 hours and could take up to 10 days.
- Shelf life of about 6 months once opened and almost a year when unopened
- UV inhibitors such as Hindered Amine Light Stabilizer (HALS) for non-yellowing protection
- Fully cures within 10 days
- Tolerates maximum temperature of 120 degrees Fahrenheit

Things to Consider Before Buying Epoxy Resin for Tumblers
If you are wondering how we gathered the brands and products, check out these factors. We advise that you use the same criteria to get ahold of a suitable epoxy material for your project!
This term refers to the thickness of the material. An epoxy’s viscosity defines its applications, such as sealing, potting, coating, and priming.
There are three levels of epoxy viscosity: low, moderate, and high. Make sure you obtain a low viscosity epoxy that can be easily layered multiple times and allows for long shelf life.
Cure time is the length of time needed for something to fully cure or dry. Epoxy resins begin to gel as quickly as 20 minutes.
These compounds produce excessive heat when left in a mixing container beyond 10 minutes. Since epoxy pours thinly, it is also a factor why they gel rapidly.
A good epoxy resin must be capable of containing UV inhibitors. A UV inhibitor is an additive that helps prevent the premature fading of gel exposed to ultraviolet or “UV” light. While epoxy resin has this additive, tumblers that are epoxy-coated should not be directly exposed to UV.
In general, epoxy resins are harder than other casting resins. Yet, this is not always the case. While ingredients of the resin have nothing to do with its hardness, its viscosity and mixing ratio greatly affects it. Make sure to get low viscosity epoxy resins to obtain the right hardness.
There is not one epoxy resin that is resistant to high heat. This material will begin to soften around 120-150 degrees Fahrenheit. Yet, there are epoxy systems that can be applied at that temperature, which can be quite expensive.
Susceptibility to Bubbles
Since low viscosity epoxy resins are thin and easier to pour using multiple layers, they allow bubbles to rise to the surface and vanish. So, go for low viscous epoxy resin.
How to Mix Epoxy for Tumblers
If you already have an idea of what epoxy resin to get, knowing how to mix it tremendously affects your application. Here is an effective resourceful way to mix epoxy for tumblers!
Step 1: Gather Materials
Firstly, get your choice of epoxy resin, measuring medicine cups, silicone cupcake pan, and a wide popsicle stick. It does not stick to silicone, which is why it is best to use them for mixing.
On the other hand, a wide popsicle stick is better than thin ones because they allow for less stirring movement in the cup, which produces fewer air bubbles.
Step 2: Measure
Using your measuring cup, get the amount that you need for hardener and resin. They are sometimes labeled as sides A and B or parts A and B. Make sure the ratio is either 1:1, 2:1, or 100:45, with the hardener being the lesser number.
Step 3: Pour Contents
Put the hardener and the resin into one silicone cup holder. There is no necessary sequence as to which of the two liquids go first. Make sure to scrape all the contents into your holder.
Step 4: Mix
Using a mixer or a wide wooden popsicle as we suggested, gently stir the mixture to prevent air bubbles. As you mix the two parts, it becomes a little bit cloudy. But once they get properly bonded, it should become clear again. Mix for about 1 to 3 minutes.
Frequently Asked Questions
1. Does low viscosity epoxy resin make end projects prettier?
When a material is deemed forgiving, it means it is easy to work with and allows for a longer shelf life. To answer this question, yes, low viscosity epoxy resin can produce prettier end results when compared to other thick resins.
2. Which type of tumbler is best to resin?
Regardless of the tumbler you choose, it is best to go for double-walled or insulated ones. Since the maximum temperature that it can come into contact with is 120 degrees Fahrenheit, a regular tumbler may not accommodate hot beverages since it can cause the cured resin to soften.
3. What materials does epoxy not stick to?
Epoxy resins bond poorly with polyvinyl chloride, acrylic, and polycarbonate plastics. They also DO NOT bond on Teflon, polyethylene, polypropylene, nylon, and Mylar.
4. How long should I turn the tumbler?
Regardless of whether you turn the tumbler using your hand or a cup turner, you must continue rotating it slowly for about 4 to 6 hours, depending on the temperature and humidity of your environment.
5. Is epoxy safe to use for tumblers?
Not all resins out there are food safe. One way to make sure the epoxy resin is safe for making tumblers is to check for food safety compliance and whether it becomes an inert plastic after it is cured.
Every reputable company will provide information on the resin they produce. For your safety, you must make sure to check all warnings and directions on whatever resin you choose to work with.
Best Resin for Tumblers – Wrap up
Tumbler crafts and arts should never feel like tedious work. Knowing the right epoxy resin to use for your project should enable you to create a long-lasting piece.
At the same time, you enjoy creating them because they are easy to use. With that, choose only the best epoxy for tumblers that are non-toxic, crystal clear, and of course, do not turn yellow over time.
