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. 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. 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. Alternatively, coating epoxies can be used for casting applications, but may need to be poured in multiple layers. This is because most of these unlimited epoxies have been slightly modified to suit the particular needs of the project. Epoxies and resins are adhesives commonly used in repairs to homes, automobiles, airplanes, and ship buildings.
When you begin to compare the many shapes and variations of epoxies, glues and resins available today, the results can cause you to scratch your head. Most epoxy coating resins and casting resins used by the average DIY artist are not high heat resistant epoxies. Most casting resins and epoxy resins that are intended for the average do-it-yourself enthusiast are not high-temperature epoxies.
