FIELD: electricity.
SUBSTANCE: in the method for sealing of tubular electric heaters, in which near-end cavities are filled with a sealing rubber-like material, the sealing rubber-like material is a mixture of an organosilicon vinyl-containing rubber, oligomethylhydridedimethylsiloxane and titanium dioxide, hardened with a solution of a platinum-chloro-hydrogen acid in isopropyl alcohol.
EFFECT: increased reliability of sealing and service life of a tubular electric heater, reduced labour intensiveness and accelerated process of sealing.
