A strong adhesive or coating made from synthetic resins that hardens when mixed with a catalyst. A type of plastic polymer known for its durability and bonding strength.
From Greek 'epi-' meaning 'upon' and 'oxy-' from 'oxys' meaning 'sharp' or 'acid,' referring to the chemical structure containing oxygen bridges between carbon atoms. The term was coined in the 1930s when these synthetic polymers were first developed.
