It is also a very durable form of resin. Installers must check the label for an expiration date before using. The main process is to apply a few layers, allowing too dry in between each application. Pure epoxy is typically just an epoxy resin and a hardener, and its slow cure rate makes it prone to sagging if it is used for overhead applications. There is a lot of labor and skill needed to install these types of garage floor coatings properly. In most cases, an epoxy that has exceeded its shelf life will be too difficult to extract from the cartridge. Essentially, epoxy resin is very versatile and can be used for different types of art and craft projects. However, when comparing the difference between the two, most are comparing a Casting Resin, Polyester Resin and an Epoxy Coating Resin. Included here is a quick guide that differentiates between some common forms of 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. It is a particularly useful type of epoxy resin thanks to its thin consistency.
