Patent Number: 052389758
Section: claims

1. A non-conductive microwave radiation absorbing adhesive comprising dissipative particles dispersed in a polymeric dielectric material chosen from the group consisting of thermosetting adhesives and thermoplastic adhesives, in which the dissipative particles range in largest dimension from 0.1 to 150 microns, and are chosen from the group consisting of solid microspheres made from a dissipative material, hollow microbubbles made from a dissipative material, solid microspheres coated with a dissipative material, hollow microbubbles coated with a dissipative material, filaments made from a dissipative material, and flakes made from a dissipative material, and in which at least one dissipative material is chosen from the group consisting of tungsten, chromium, aluminum, copper, titanium, titanium nitride, molybdenum disilicide, iron, and nickel. 2. The absorbing adhesive of claim 1 in which the polymeric dielectric material is chosen from the group consisting of polyamides, polyethylenes, polypropylenes, polymethylmethacrylates, urethanes, cellulose acetates, vinyl acetates, epoxies, and silicones. 3. The absorbing adhesive of claim 1 in which the volume loading of the dissipative particles is between 1 and 60 percent. 4. The absorbing adhesive of claim 3 in which the volume loading of the dissipative particles is between 10 and 50 percent.
