Abstract
Methods of bonding together substrates that do not require use of primers, mixing, fixturing, or autoclaving. These methods can include the steps of disposing an adhesive layer on a bonding surface of either substrate, the adhesive layer comprising a curable composition that is dimensionally stable at ambient conditions; either before or after disposing the adhesive layer on the bonding surface, irradiating the adhesive layer with ultraviolet radiation to initiate curing of the curable composition; placing one substrate so as to be bonded to the other substrate by the adhesive layer; and allowing the adhesive layer to cure.
