FIELD: chemistry. ^ SUBSTANCE: invention relates to anaerobic sealing compositions used for sealing and locking threaded cylindrical or flanged joints. The composition contains ether of methacrylic acid, i.e. a mix of aromatic and aliphatic oligo ether acrylates containing at least 10 wt % of aromatic oligo ether acrylate, the initiating additive and accelerating additive, i.e. pre-alloyed mix of sulphonamide, amine and hydrazine compounds taken in the molar ratio of (2-2.5):1:1, a stabilising additive and filler. ^ EFFECT: improved quality of anaerobic composition due to reduction in time of assembling at ambient temperature after introducing proposed composition into threaded cylindrical or flanged joint. ^ 2 tbl, 20 ex |
