Abstract: The present disclosure provides methods and articles useful in sealing fasteners, including seal caps and methods of their use, and in particular light weight seal caps having higher dielectric breakdown strength, lower weight, and/or lower wall thick-ness. In some embodiments, the seal caps according to the present invention are made of a material having a dielectric breakdown strength of greater than 1.0 kV/mm, in some embodiments greater than 15.0 kV/mm, and in some embodiments greater than 50.0 kV/mm. In some embodiments, the seal caps according to the present invention are thin-walled, having an average wall thickness of less than 1.5 mm and in some embodiments less than less than 0.5 mm In some embodiments, the seal cap comprises a polyurethane polymer, a polythioether polymer, a polysulfide polymer, a fluorinated thermoplastic polymer, a THV polymer, a fluorinated thermo-set polymer, an engineering thermoplastic, and/or a PEEK polymer.

Abstract: Certain polythioether polymers are presented, as well as compositions which are radiation curable to polythioether polymers and seals and sealants comprising same. The compositions radiation curable to polythioether polymers include those comprising: a) at least one dithiol monomer; b) at least one diene monomer; c) at least one polyyne monomer comprising at least two ethyne groups; and d) at least one photoinitiator. In some embodiments, the polyyne monomer is a diyne monomer. In some embodiments, the composition also comprises at least one epoxy resin. In another aspect, the compositions radiation curable to polythioether polymers include those comprising: f) at least one thiol terminated polythioether polymer; g) at least one diyne monomer; and h) at least one photoinitiator. In some embodiments the thiol terminated polythioether polymer comprises pendent hydroxide groups.
