A susceptor composition that can bond two or more layers or substrates to one another and that can be used to coat or cut a substrate. The susceptor composition is activated in the presence of radio frequency (RF) energy. In one embodiment, the susceptor composition of the present invention comprises a susceptor and a carrier. The carrier and susceptor are blended with one another and form a mixture, preferably a uniform mixture. The susceptor is present in an amount effective to allow the susceptor composition to be heated by RF energy. In a preferred embodiment, the susceptor also functions as an adhesive. The susceptor is an ionic or polar compound and acts as either a charge-carrying or an oscillating/vibrating component of the susceptor composition. The susceptor generates thermal energy in the presence of an RF electromagnetic or electrical field (hereafter RF field).

1. A method of bonding or adhering a first substrate to a second substrate, comprising interposing a composition between the first and second substrates, said composition comprising an ionomer and a polar carrier, wherein said carrier and said ionomer are blended substantially with one another and form a mixture, and wherein said ionomer and/or said carrier are present in amounts effective to allow said composition to be heated by RF energy; and applying RF energy to said composition to heat said composition, thereby causing the first and second substrates to become adhered or bonded, with the proviso that said ionomer is not a quaternary ammonium salt or a sodium polystyrenesulfonate and said polar carrier is not water.
