FIELD: polymers, anticorrosive materials. ^ SUBSTANCE: invention relates to polymeric compositions used for protection against corrosion. Polymeric composition comprises epoxidated rubber or dimethylsiloxane rubber as a polymeric binding agent, polyamide resin or polymethylsilazane as a nitrogen-containing hardening agent, talc or mica as a filling agent, aerosil as a thixotropic additive and electrolytic nickel powder or powder of the alloy system Al-Fe-Cu as a current-conducting additive. The composition can comprise additionally epoxy resin in the amount 10-20 mass. p. Invention provides preparing the composition showing high protective properties in all-climate conditions that allows increasing exploitation period of articles. Invention can be used for filling the internal lap cavity (before welding) formed in the pointed arc welding of metals and alloys. ^ EFFECT: improved and valuable properties of composition. ^ 7 cl, 2 tbl |
