NUSIL AVIATION AND DEFENSE SILICONESAviation and defense siliconesHIGH-PURITY SILICONES THAT HELP AVIATION AND DEFENSE AIRCRAFT TAKE FLIGHTBacked by our extensive history, NuSil has developed silicones with a broad operating temperature rangethat are optimized to remain flexible at extremely low temperatures and resist breakdown at elevatedtemperatures. We can formulate silicones and engineer fabricated parts for sophisticated systems, such asengines and electrical and pneumatic systems.To meet increasing demands for fuel and solvent resistance, NuSil formulates fluorosilicones for long-lastingstability in harsh environments. They resist degradation, which makes them highly suitable for the mostdemanding aircraft applications.With a diverse range of off-the-shelf and customized products, NuSil offers one of the most extensive solutionsfor the aviation and defense industries.FLUOROSILICONESCOATINGSNuSil’s fluorosilicone portfolio, one of the most diverseavailable, resists degradation to protect the aircraft’s outermold line and seals from damaging fuels and solvents. Theyare formulated to perform in broad operating temperatureranges — reliability proven through decades of flight service.Primarily used on aircraft exteriors, siliconecoatings provide UV protection and can operateunder a wide range of temperatures. They can beused on a variety of aircraft and control surfaces.ADHESIVES AND SEALANTSTHERMALLY AND ELECTRICALLY CONDUCTIVEMATERIALSNuSil silicone adhesives range from traditional liquidadhesives to novel peel-and-stick films to pressure-sensitiveadhesives. Primers are also available to improve adhesion.NuSil thermally conductive silicones facilitate heattransfer from electronic devices without adding stressto systems. Our electrically conductive silicones cancarry a current, while our dissipative silicones enablestatic to dissipate continuously rather than accumulateand discharge, thus causing damage.POTTING AND ENCAPSULATING MATERIALSNuSil potting and encapsulating silicones provideexcellent protection against thermal cycling, shockand contaminants, such as moisture and debris.4Version uploaded ddefense
