What is Epoxy Resin?

Let’s see the chemistry behind the epoxy resin. It comes from an epoxide group, a colloquial name of the resin. It might also be referred to as polyepoxides that are from reactive classes like polymers or, prepolymers. Seems like jargon to you? Well, it’s a bit of a chemistry thing.

The epoxy resin comes as a low-viscosity liquid that reacts with a co-reactant like polyfunctional amines (hardener compound) to form the hard curing state.

When you mix the resin and hardener, it allows you for a certain amount of time before you finish up making your coasters. Epoxy might also be used for many other projects like metal coating, as an insulator or, adhesives, etc.

Who Can Use Epoxy Resin?

From the definition of epoxy resin, you can understand that it contains some corrosive chemical ingredients. And, they come in contact to form a hard solid stage from the initial liquid stage. So, when playing around with resins, it’s highly necessary to be patient with awareness and skills or at least have proper knowledge of the application.

With that being said, it’s recommended only for adult people. Children might only engage with proper safety equipment to assist in your coasters making projects. Those involve some mixing and pouring activities along with their wonderful childish creative ideas.

Polyester Resin Vs. Epoxy Resin: What is Best for Coasters?

Have you ever come across these two types of products? Yes or no, these are two different types of resins! Both might be suitable for a variety of similar craftworks. But, there’s a slight difference in which epoxy resin is best for making coasters.

So, wondering what are the differences between polyester resin and epoxy resin? And why epoxy resin is best for coasters? Let’s find out!

1. Bonding Strength

Epoxy resin is known for its incredible bonding strength. It’s capable of withstanding a lot more pressure than polyester resin. You can expect it to hold up to 2,000 psi while polyester resin’s capacity is less than 500 psi. As a result, epoxy will give you a more durable casting and coating. Now, as you can see, epoxy will make your coasters stronger.

2. Cost

Epoxy resin is comparatively more expensive than polyester. You’d have to spend more money if you want to make coasters with it. Well, it’s stronger and comes with a better formulation that’s suitable for coasters and crafting so it’s worth it.

3. Wear-Resistance

When it comes to wear-resistance, epoxy easily wins because it’s much more durable. It can resist cracking, peeling, environmental damage, corrosion, etc. Compared to that, polyester is rather fragile. If you want long-lasting coasters, epoxy is the way to go.

4. Odor

Polyester resin can be smellier than epoxy so you’d have a hard time working with it. On the other hand, high-quality epoxy resins produce little to no odor, making them more pleasant to be around.

5. Water-Resistance

Epoxy can be completely waterproof as it can prevent water from breaching in. Therefore, it isn’t easily damaged by moisture. Polyester resin isn’t all that effective in resisting moisture. It’s known to be water-permeable, so it will allow water to pass through. You want your coaster to be water-resistant because you’re likely to put wet glasses or bottles on it. That’s why epoxy is the better choice.

6. Cure Time

As we’ve mentioned before, cure time for resins can vary depending on the temperature and humidity. Polyester resin can be slightly faster than epoxy. However, the difference isn’t all that big. The curing time can be manipulated by changing the environment such as – using UV torchlight or direct sunlight.

7. Shelf-Life

Epoxy offers a longer shelf-life than polyester resin. You can leave it to sit in your garage for many years as long as you haven’t mixed the substances. Polyester resin won’t last that long.


With the best resin for coasters, you will be able to break your limits, explore your creativity, and make astoundingly beautiful coasters! Our in-depth review is filled with some of the best products on the market. They are all beginner-friendly and super-effective.

So, go ahead and pick any of them to start molding amazing coasters or use them in other projects!

Frequently Asked Questions

1. Is cured resin heat resistant? What temperature can a resin coaster withstand?

Answer: Cured resin’s heat resistance depends on the quality of the epoxy. The standard heat-resistant epoxies can resist heat to some degree. You will find the common ones to withstand up to 120-150 degrees Fahrenheit. Some of the specially formulated ones can offer up to 600-degree Fahrenheit of heat resistance.

You can find out how much temperature a specific model of epoxy can handle just by reading the packaging or asking the salesmen.

2. Can you melt hardened resin? Does resin melt in the sun?

Answer: Yup, it’s possible to melt hardened resin. Epoxies come with a glass transition temperature (Tg) which is also known as softening point. If you manage to heat the hardened resin above its Tg, it will start debonding and softening. Most of them will start melting from 200 degrees. You can use a hot air gun for that.

Whether resin will melt in the sun depends on the quality of the epoxy. If it’s a heat-resistant one that comes with UV-ray protection, it won’t melt in the sun. Most of the products we’ve reviewed are suitable for outdoor projects.

3. What is the best heat resistant resin for coasters?

Answer:Teexpert – Crystal Clear Resin Kit” is one of the best resins for making heat tolerable coasters. It’s designed to resist UV rays so it can withstand long-time exposure to the sun with ease. As a result, it can resist heat without any problem. So, feel free to use it for outdoor applications!

4. Do you need heat-resistant resin for coasters?

Answer: Of course, you need a heat-resistant resin for coasters. That’s because you will be placing hot glasses or bottles on the coasters. If the coaster isn’t built with heat-resistant resin, it’s going to melt or soften. That’s something you don’t want now, do you?

So, make sure to get a heat-resistant resin kit for making your coaster. Otherwise, it won’t be able to serve your purpose. Fortunately for you, all of our reviewed products are heat-resistant!

5. Can you put hot drinks on resin coasters?

Answer: Resin coasters made with heat-resistant epoxy resin will be able to withstand the heat of hot glasses or bottles. They will not melt or soften. You won’t have to deal with glass or bottle marks either. However, you shouldn’t place burning hot drinks on the resin coasters.

They aren’t capable of withstanding extreme temperatures. Don’t put something on your resin coaster right after taking it out of the microwave!

6. Why do my coasters stick to cups?

Answer: It’s simply because of the condensation that causes the bottom of cold bottles or cups to be wet. When that happens, a hermetic seal is created by the water which prevents the passage of air. As a result, when you lift the cup, you end up creating a vacuum between the coaster and the cup.

This, in turn, results in the creation of a force that causes the coaster to stick to the cup.

7. How much resin do I need for coasters?

Answer: For creating a single beautiful coaster, you will need at least 3 ounces of resin. Make sure to mix equal amounts of hardener and resin. Stir them for 2 to 3 minutes to get the perfect mixture. You will need more for creating multiple coasters.

Just remember to be careful and follow the instructions if you’re a beginner.
