Epoxy is a type of strong adhesive or a coating material made from a class of resins that harden when combined with a hardener. It is commonly used in construction, manufacturing, and various crafts because of its durability and resistance to chemicals and moisture. Epoxy can also be used to create strong bonds between different materials, making it valuable in woodworking, metalwork, and even repairing objects.
The word "epoxy" comes from the Greek prefix "epi-" meaning "upon" or "above" and "oxy," derived from the Greek word "oxys," meaning "sharp" or "acid." This reflects the chemical properties of the material, as it typically involves a reaction between resin and hardener.
