Epoxy resin is a chemically created versatile substance having diverse applications in various fields. Epoxy in its liquid form was primarily used as structural and engineering adhesive in aircrafts, automobiles, ships/boats, bicycles, snowboards and skis. It was also used as a bonding agent in products made of wood, glass, stone, metal and plastic. With the passage of time, the use of epoxy evolved from mere adhesive to a substance that can be used in a variety of art and craft projects. How come? Let's dive into the world of epoxy.
What is Epoxy Resin Made up of? Epoxy resin is a combination of resin and hardening (curing) agent. It is thermosetting which means it hardens when exposed to heat or radiation. After hardening, epoxy resin becomes shiny and glossy. Once the epoxy is cured (hardened) it cannot be uncured. Epoxy resin is made up of bisphenol (a combination of acetone and phenol) and epichlorohydrin (derived from allyl chloride which is a chlorinated sub-chemical of propylene). Phenol was previously extracted from coal tar but nowadays it comes from petroleum.
