Epoxy resins, sometimes called polyiodides, are a group of reactive prepolymers and polymers which contain at least one epoxide group. The resins can be reacted (cross linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants having polypractical amines, acids and acid anhydrides, phenols, alcohols and thiols. The co-reactant is often named hardener or curative, and the crosslinking reaction is usually pointed at as curing. The thermosetting polyepoxides are believed to have good mechanical properties, and high temperature and chemical resistance. However, when cured with a curative, the mechanical properties are also dependent on the curative-polyepoxide ratio. An excess of amine usually results in inferior mechanical properties.
To gain the optimal performance properties, the epoxies are basically cured with stoichiometric or near-stoichiometric quantities of curative. As with other groups of thermoset polymer materials, blending different grades of epoxy resin, as well as use of additives, plasticizers or fillers is normal to achieve the desired processing and/or final properties, or to decrease cost. Blending, and use of additives and fillers is often referred to as formulating.
