The term “epoxy” gets slung around as if there were only 1 type of epoxy used in every situation. But contrary to the popular misconception, “epoxy” actually comes in a wide variety of hardeners and resins. And here they are:
The resins used in epoxy don’t offer variety that the hardeners offer. There are 3 types of resins:
- Bisphenol A Resin – This resin has a lot of viscosity, a moderate amount of flexibility, and a moderate amount of chemical resistance.
- Bisphenol F Resin – This resin is similar to the “Bisphenol A” variety, except its flexibility is on the lower end of the spectrum.
- Phenolic Novolac Resin – This resin offers a high amount of viscosity, but because it’s a novolac, it will become very hard, which means there is no room for flexibility. Additionally, it is very chemical resistant.
Depending on what type of application the flooring or painting installer is searching for, they have a variety of epoxy options to choose from. And a part of that reason is because of these (3) different types of epoxy resin.
Now, although there are 3 different resins to choose from, the epoxy hardeners have the largest range of selection, by offering up to 6 different hardeners. Each of these hardeners has different sets of properties that they can offer, making the epoxy line-up a smorgasbord of commercial coating options.
