FIELD: chemistry.
SUBSTANCE: frost-resistant sealing compound contains a polymer-based component A as the basic paste and component B as a curing agent. Component A contains a thiol-containing polymer, silicon dioxide, chlorinated paraffin wax, natural chalk, titanium dioxide, tetraethoxy silane or bis-triethoxysilylpropyl polysulphide. Component B contains manganese dioxide - curing agent, chlorinated paraffin wax, natural chalk and ethylene glycol, diphenyl guanidine and sulphur as a vulcanisation accelerator, white soot and water. Before use, components A and B are mixed in ratio of 2-3:1 (pts.wt), respectively.
EFFECT: invention increases frost-resistance with maximum joint movement.
