FIELD: chemistry.
SUBSTANCE: invention relates to sealant compositions, which are suitable in areas of application, associated with lightening strikes, high tensile elongation and low specific weight. Sealant composition includes base composition, which includes sulphur-containing polymer, curing agent composition, which includes curing agent and electroconducting filling agent in at least one of base composition or curing agent composition, where said electroconducting filling agent contains carbon nanotubes and conducting carbon soot and where average size of particles of conducting carbon soot is larger than average diameter of particles of carbon nanotubes. Sealant composition includes: base composition, including sulphur-containing polymer; curing agent composition, including curing agent and electroconducting filling agent in at least one of base composition or curing agent composition, where said electroconducting filling agent contains carbon nanotubes and conducting carbon soot and where average size of particles of carbon nanotubes is larger than average diameter of particles of conducting carbon soot. Sealant composition includes: base composition, in fact nickel-free and containing sulphur-containing polymer; in fact nickel-free curing agent composition, containing curing agent and in fact nickel-free electroconducting filling agent in at least one of base composition or curing agent composition, where said electroconducting filling agent contains carbon nanotubes and conducting carbon soot, where average diameter of particles of conducting carbon soot is larger than average diameter of particles of carbon nanotubes. Sealant composition includes: base composition, in fact nickel-free and containing sulphur-containing polymer; in fact nickel-free curing agent composition, containing curing agent and in fact nickel-free electroconducting filling agent in at least one of base composition or curing agent composition, where said electroconducting filling agent contains carbon nanotubes and conducting carbon soot, where average diameter of particles of carbon nanotubes is larger than average diameter of particles of conducting carbon soot.
EFFECT: sealant compositions possess improved conductivity, relative tensile elongation and specific weight.
