Epoxy is a thermosetting epoxide polymer. It also called polyepoxide. It cures when mixed with a catalyzing agent or hardener. Most common epoxy resins are produced from a reaction between epichlorohydrin and bisphenol-A.
Epoxy adhesives are suitable for high-strength bonding of a variety of materials and have excellent resistance to harsh environments, chemicals, and water. It is used to produce satisfactory joints between nylon and metal, wood glass and leather. It is applied with a wooden paddle or spatula. They will cure at room temperature in 24 to 48 hours.
