A method of forming a cured thermoset composition by applying radio signals having a frequency of about 1 to 100 MHz to a composition comprising a major portion of thermoset and a receptor, said receptor having a dissipation factor of about 0.1 or greater and a dielectric constant of at least 0.1 or greater, said receptor selected from the group consisting of alkali or alkaline earth metal sulfate salts, aluminum trihydrate, quaternary ammonium salts, phosphonate compounds, phosphate compounds, polystyrene sulfonate sodium salts or mixtures thereof, said method comprising the steps of: (a) applying said composition to a substrate; (b) applying radio signals to the composition deposited on the substrate; and (c) dissipating the radio signals received by the receptor as thermal energy in an amount effective to cure the composition to a thermoset bond.
