Epoxy Vs. Resin Explained

So what is the difference between the epoxy and the resin, or are they the same?  

Simply stated, the term epoxy is commonly used to refer to the cured end product of the necessary components within epoxy resin. It is also a colloquial name for epoxide.

This cured end product is the result of when you mix resin with hardener (two-part resins) or expose it to ultraviolet light (UV resin)

Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers. Of course you can find where to buy resin for your project from our online store or other online sources, but you should know there isn't a "one size fits all" approach. 

We specialize in manufacturing various epoxy resin types specific to several different types of uses. You can see a comparison chart detailing our various types of epoxy resin we manufacture by following this link here

What Is A Resin?

In polymer chemistry and material science, the resin has been a solid or high viscous substance of plant or synthetic origin that is typically convertible into polymers. More recently, synthetic resins have been formulated using epichlorohydrin and diphenols, or bisphenol-A with epichlorohydrins. 

There are several types of these combinations many with specialized formulas, but these are the most common epoxy resin

  • Urethane resin
  • Polyester resin
  • Casting resin
  • Epoxy coating resin

 

Urethane Resin

  • This is a one-component water-based urethane that will protect your project with a nice glossy finish. 
  • These resins typically have a shorter working time. 
  • Excellent for coating metals, wood, and concrete. 
  • VOC-free
  • Non-toxic
  • virtually odor-free

Polyester Resins

  • Cure very hard
  • Polyester is less expensive than most epoxy resins
  • That is commonly used in the marine industry such as boat building
  • Used for the casting of bumpers or gutters and repair of plastic parts.

 

Casting Resin

  • They are typically low viscous compared to epoxy coating resin
  • They are made explicitly for casting works such as molds, figurines, filling wood, deep pour, and jewelry.
  • Unlike coating resins, casting resins have a thinner consistency and take a longer time to dry. Casting resin takes a longer processing time, and it can take up to one week to cure completely.
  • This thinning feature of casting resin allows it to penetrate and fill even the tiniest gaps and cavities.
  • Casting resin allows you to cast thicker layers as compared to epoxy resin.
  • The thin consistency enables layers of paint to mix quickly.
  • Casting resin is specially made for particular applications.
  • They can be colored with color pastes, alcohol inks, and color pigments.

Epoxy Resin for coatings

  • That is mainly used coating applications
  • Epoxy coating resin has a more viscous consistency as compared to casting resin.
  • It dries or cures faster than casting resin.
  • Compared to casting resin, epoxy coating resin has relatively shorter processing times.
  • Because the ink layers do not mix, they can be better controlled.
  • Epoxy coating is more resistant to mechanical influence as compared to casting resin.
  • Epoxy coating is suitable on rougher surfaces and is water-resistant.
  • They can be colored with color pastes, alcohol inks, and color pigments.

 

Safety Precautions:

It is important to always to wear protective clothing and a breathing mask when dealing with epoxy resin and especially if you are in a closed room to cast resin.

Using high-quality clear casting resin and proper mixing ratios gives you better results for your project. Not knowing whether to use casting resin or epoxy coating resin can be problematic for your project.

What’s the best resin or epoxy mix to make a crystal ball? Used the basic 1to one ratio stuff and had lots of bubbles and the bottom took a week to harden??

I have a round tray with a 2" rim. I want to coat the bottom and embed little keepsakes (beach glass, sea shells, etc.) It will be used for serving, so, nontoxic is important. Which if your products would be best? Thanks!

My project is top secret b/c it’s guaranteed to be a money maker!! 🤑 But, my mold didn’t hold and I have to start again. Your article explaining the different types of product is helpful! Now, I’m going to peruse your site to see what products I can buy.

Hello,

I’m looking for the best way to inlay a pink granite “look” on a busy concrete walkway.

The existing broken inlay has little chunks of what looks like crumbled clay brick pieces. I would like to show you photos of the existing inlay and would appreciate suggestions. How may I send the photos?

Hi, that is a great explanation of resin. How about resin and natural timber. I want to upcycle an old a metal framed tabletop with natural timber slices for use outdoors. What is your advice about this and using resin? It previously had a tiled surface, I don’t want to repeat that look. Marian

Thank you for teaching this handy breakdown of resin types and uses! I’ve downloaded your pdf guide!

Nice! Epoxy-coating resin is thicker. It cures or solidifies more quickly than molding resin. Epoxy-coating resin has comparatively faster production periods than casting resin. The ink levels can be better regulated because they don’t combine. https://seattleepoxyflooringwa.com/

I understand the mix ratio of an epoxy might be defined as 2:1, but what if my process is slight imprecise? What is the difference in the end product between a ratio of 1.9:1 and 2.1:1?

I’m new to using resins but I want to make a thin resin based saxophone that I can put into a picture frame. I can’t find a mold and I actually need directions. Can you help me with this?

I’m looking for a resin or epoxy that is UV resistant as well as heat resistant. I want to make trivets so it would need to be able to handle 350-425 degrees.
Thanks in advance. I’m new to this and I really appreciated this article.

I want to use epoxy mixed with pea stone to fill the gaps in a flagstone walkway. Not sure exactly what kind of epoxy would be needed for this kind of application. Any advice?

Thanks very much for the explaination. I’ve been woodworking for years but am still a novice when it comes to resins and this was really helpful.

I am still fairly new at using epoxy/resin and I am having the hardest time finding coverage information. Most kits that I see in the store will state a square footage that the kit will cover but none of them state the thickness of the pour that that square footage is based on. Even the calculators aren’t clear on the thickness. Where can I find that information.

I must need better ventilation. I read the entire article and still don’t get it. I better turn up the exhaust fan and read it again.
Seriously though, I’ve been experimenting with a 2 part, 50/50 mix with average results. Your article splains a bunch. Thanks a ton.

Thank goodness someone took the time to explain in simple terms what the differences were because if I watch another YouTube explanation my head will explade

This article was an excellent explanation for those of us just getting started in resin casting. Its so important to respect the materials in any “hobby!” Just because its a hobby, doesnt mean it is risk-free.

I am a total novice. I want to make a miniature bath with “waterl, a nd when hardened, top it with crystal bubbles, for a doll house. Tutorials on line demonstrate this with epoxy resin using equal quantities of resin and hardener. I’ve just seen another tutorial for silk flower arrangement using casting resin and a much smaller quantity of hardener. Which is better for my purposes?

I saw a canvas with resin/epoxy poured onto it in a dripped manner that had an abstract appearance over the painted canvas. I would like to try it but I am unsure which product would work. I do have pics to share of the art that I am trying to emulate. BTW, I am not an artist- just wanting to be a bit creative.

About time someone explained it like this.. Amazing job explaining the differences. I am also thrilled you covered the importance of protective gear.

Could you please explain to me why after a project has been poured and set up say a 3 tier cake mold why after putting it together it will start bending usually the bottom tier but sometimes the middle one also, what am I doing wrong? I am using Clear Epoxy Resin.
