rocket engineering. SUBSTANCE: composition comprises hydroxyl-containing polybutadiene rubber containing 0.9-2.0% of hydroxyl groups, 4,4-diphenylmethane diisocyanam, chain e.g. 1,4- butylene glycol, cross-linking agent, e.g. trimethylolpropane, plasticizer, e.g. transformer oil, zinc oxide and hardening catalyst, e.g. tin dibutyl dilaurate. Composition makes it possible to attain high service reliability of charges and simplified technology for manufacturing charges. EFFECT: improved properties of the fasthardening strengthening composition. 2 tbl
