A lot of people are asking, Epoxy vs Resin, What’s the difference? Does it really matter? Here are a few things that seem to make sense and of course you have to factor in colloquialisms. In the builder world, they talk Epoxy, in the artist community they talk Epoxy-Resin.

Let’s look at the Artist side first, people who make jewelry, crafts, molds, pendants, countertops, tables, etc. For them, if asked, “What did you make this out of?” they would reply “Resin,” “Casting Resin” or “Epoxy Resin.” the cured end product of mixing epoxy resin and a hardener which has a chemical reaction and solidifies over time. Usually 1:1 A and B parts.

The builder side, now here is where things get more in-depth and complex. When you are dealing with Epoxy being used in public areas, certain building code standards come into play, is it food safe? Is it non-slip? Does it meet health codes? They are also mixing in other elements and products like colors, metallic and mica chips, sand, and other components. What will the reactions be, will there be odors, etc. So for them colloquially, Epoxy serves the purpose.

Wikipedia notes: https://en.wikipedia.org/wiki/Epoxy

Epoxy refers to any of the basic components or cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group.[1] Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups.

Art 

Epoxy resin, mixed with pigment, may be used as a painting medium, by pouring layers on top of each other to form a complete picture.[21] It is also used in jewelry, as a doming resin for decorations and labels, and in decoupage type applications for art, countertops, and tables.

So what’s the definitive answer? It depends on the use and then the colloquial applies, for arts and crafts = Epoxy Resin. For builders, contractors, and tradesmen = Epoxy (Floor/wall/shower coatings) Epoxy and decorative countertops, Epoxy paint.
