Radio frequency cure of thermoset-receptor compositions

A method of forming a cured thermoset composition by applying radio signals having a frequency of about 3 to 35 MHz at a voltage ranging from about 1000 to 50,000 volts and an average current ranging from about 0.05 amps to 5 amps 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 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) placing the substrate between two plates and 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 said composition to a thermoset bond.
