Epoxy resin is a type of synthetic polymer that is made from a combination of two main components: resin and hardener. The resin is typically made from bisphenol-A (BPA) and epichlorohdrin, while the hardener is usually a polyamine or anhydride. When these two components are mixed together, they undergo a chemical reaction that results in a hard, durable material that is resistant to water, chemicals, and heat. Epoxy resin is commonly used in a variety of applications, including coatings, adhesives, and composites.

​An epoxy flooring system typically consists of several layers. The first layer is a primer, which helps to prepare the surface for the subsequent layers. The second layer is the base coat, which provides the color and texture of the floor. The third layer is the epoxy layer, which is a thick, self-leveling layer that provides durability and chemical resistance. The fourth layer is the topcoat, which provides a protective layer that is resistant to scratches, stains, and chemicals. Some epoxy flooring systems may also include a sealer layer, which helps to enhance the durability and longevity of the floor.
