FIELD: glue compositions. ^ SUBSTANCE: invention relates to high strength heat-stable cold hardening glue compositions and can be used in articles of aircraft equipment and in other branches of industry. The composition comprises epoxide base and oligoamide-base hardening agent, mixture of epoxy resins as epoxide base, and oligoamide as a hardening agent representing product of polycondensation of dimerized methyl esters of higher unsaturated dicarboxylic acids of electrochemical synthesis and polyethylene polyamine or its mixture with [4,4'-(N,N'-bismaleimide)]diphenylmethane or with oligoimide, and additionally it comprises an elastifying additive - low molecular copolymer of butadiene and acrylic acid nitrile with terminal chlorobenzyl groups or chlorine-containing reaction resin and catalyst. Invention provides enhancing strength of glue joints in temperature shifts below 300°C, enhanced water resistance and tropic resistance and able to work at temperature 300°C for 50 h. ^ EFFECT: improved and valuable properties of composition. ^ 3 cl, 2 tbl, 1 ex |
