Colour paste
A colour paste is a pigment paste, which can impart a transparent or opaque colour to resin. For example, a quantity of polyurethane colour paste can be added to a casting resin to give the resin the desired colour. Polyurethane colour pastes are known for their strong colouring power.

EP resin - epoxy resin
The resin component is prepared by condensation and addition of epichlorohydrin and a divalent or multivalent phenol derivative. The reaction between these two raw materials produces the epoxy resin. The epoxy group found twice in each molecule of the resin is highly reactive and can react with appropriate substances called hardeners. Polyamines and polyamides are most commonly used as hardeners. These substances are able to open the ring at the epoxy group by possessing reactive hydrogen atoms. The curing process is an exothermic reaction, so heat is released. for more info, see: https://www.v-sure.eu/nl/producten/epoxy

Epoxy
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/
