FIELD: composition for corrosion protection of basic constructional materials (steel, concrete). ^ SUBSTANCE: claimed composition contains (mass %): polymeric film-forming substance 40-52; natural fine-grain iron alpha-oxide 11-27; organosilicon curing agent 1`2-17; thiocol 7-10; synthetic silica 3-5; strontium chromate 7-9. Solution of epoxy resin in xylene and acetone is used as polymeric film-forming substance. Natural fine-grain iron alpha-oxide contains (mass %): silica, aluminum oxide, magnesium oxide, and calcium oxide not more than 2.5; 1.8, 0.2, and 0.3, respectively and Fe2O3 85-95 %. As organosilicon curing agent organosilicon amine derivatives are used. ^ EFFECT: coating of increased fuel resistant and durability in high aggressive medium, containing, in particular, fuel with water impurity. ^ 2 tbl, 6 ex |
