Abstract
The present disclosure is generally directed to a method of curing an ionic liquid epoxy mixture using an electromagnetic signal. First, an ionic liquid epoxy resin comprising ionic liquid epoxide monomers and, optionally, diluent epoxy resins and powdered fillers, is combined with a curing agent to form an ionic liquid epoxy mixture. The mixture is then applied as a coating onto a surface of a material. The coating is placed in contact with a second surface of the same material or a surface of another material. An electromagnetic signal, which in some instances is a microwave signal, is applied to the coating. Following application of the signal, the ionic liquid epoxide monomers polymerize and the mixture cures, adhering the surfaces together. Alternately, the epoxy mixture is applied to a surface and cured with microwaves to form a protective coating as in cladding or paint.
