Epoxy

A material created by polymerizing a mixture of two starting compounds, the resin and the hardener. When the resin is mixed with a specified catalyst, curing is initiated. During curing, molecular chains react at chemically active sites, resulting in an exothermic reaction. Covalent bonds formed between the epoxide groups of the resin and the amine groups of the hardener (catalyst) result in the cross-linkage of the polymer, which results in a strong and rigid epoxy structure.
