PURPOSE: To provide an adhesive which exhibits strong adhesive power and by which bonding operation can be carried out efficiently, and to enable the adhesive to be applied to a wide range of adherends, by a method wherein a strong dielectric having dielectric hysteresis loss in radiofrequency electromagnetic field, or a hydrated aluminosilicate is added to a thermosetting resin. n CONSTITUTION: A strong dielectric having dielectric hysteresis loss in radiofrequency electromagnetic field and/or a hydrated aluminosilicate are/is added to a thermosetting resin. Pref. barium titanate is used as the dielectric. It is preferred to add further a ferromagnetic substance having magnetic hysteresis loss in radiofrequency electromagnetic field to the radiofrequency heating curable adhesive obtd. by adding either or both of the strong dielectric and the hydrated aluminosilicate to the thermosetting resin, because exotherm efficiency is synergistically improved and bond strength becomes higher. Preferred examples of said dielectric are barium titanate and γ-iron oxide. n COPYRIGHT: (C)1981,JPO&Japio |
