Epoxy or polyepoxide is a chemical compound. It is an epoxide polymer composed of 2 carbon atoms (C) and 1 oxygen atom (O) in a ring-shaped structure. Epoxy distinguishes itself from polyester by, for example, greater flexibility, the fact that it adheres to almost any surface and the fact that it yellows under the influence of UV and therefore has to be finished with UV-resistant lacquer. for more information, see https://www.v-sure.eu/en/knowlegde-center/inspiration/creating-a-river-table/
