The epoxy coating resin has a more viscous consistency compared to the casting resin. Dries or cures faster than molten resin. Compared to casting resin, epoxy coating resin has relatively shorter processing times. Because the ink layers don't mix, they can be better controlled.
The most notable difference between these two compounds is their intended use. Epoxy coating resin is designed for surface coating applications, while casting resin is mainly used for jewelry, molds, or figurines. However, we must realize that these two compounds could be used interchangeably, but we will discuss this matter later in the article. The most obvious difference between the two is the intended use.
Epoxy resins are designed for coating applications, while casting resins are intended for casting applications such as molds, figurines, jewelry%26.However, that's not to say that either of them works for their opposite intended uses, but rather that we'll talk about it later. Epoxy is a specific type of two-part resin. Epoxy resins are the most commonly used type of resin for making crafts and creating resin art. Because they are the easiest to measure and mix, epoxy resins are the ones I recommend for resin beginners.
Both epoxy and resin adhesives need to be mixed before use, but epoxy hardens much faster than glue. Epoxy is generally more expensive than resin, due to its strength and formulation requirements. Resin is more popular for making crafts and jewelry, due to its low cost. However, remember that you get what you pay for.
Casting resins often have the ability to vary mix ratios, ultimately allowing for a variation in hardness. The reason is that casting resins have a slower cure speed and as such create less heat, allowing you to pour thicker layers. This property makes casting resins suitable for river tables, molds, figures, and deep encapsulation projects. As a result, your working time will be extended and you will have plenty of time (compared to epoxy) to make adjustments or finishing touches.
Therefore, when you compare the two, you are actually relating the differences between epoxy coating resin, casting resin, or polyester resin and not the difference between epoxy resin and resin. While this doesn't usually matter when using epoxy to coat other materials, it's important to consider the aesthetics that this type of resin will provide you with. Resin is used in a wide range of applications, including DIY projects, model making, art, surface finishing, adhesives and more. It is worth noting that, despite these traditional applications, it is often possible to replace one type of resin with another (depending on the application, of course) without any catastrophe occurring in your projects.
Most casting resins and epoxy resins that are intended for the average do-it-yourself enthusiast are not high-temperature epoxies. However, as you've seen, there are 3 types of resin that are commonly used in projects and it's important to select the right resin for the right job. Most casting resins and epoxy coating systems ARE NOT RECOMMENDED for permanent outdoor use or direct exposure to cast iron. Note that most epoxy coating resins and casting resins are not recommended for outdoor projects or where they are exposed to UV rays.
