Epoxy flooring is typically made up of a combination of resins and hardeners. The resins are usually a type of thermosetting polymer that is mixed with a hardener to create a chemical reaction that results in a durable, hard, and smooth surface. Additionally, epoxy flooring can include additives such as fillers, pigments, and aggregates to achieve the desired look and texture. The specific materials used in an epoxy flooring system can vary depending on the manufacturer and the intended use of the flooring.
