COMPOSITION FOR ANTICORROSION COATING (VARIANTS) Russian patent published in 2006 - IPC C09D5/08 C09D163/00 C09D163/02 C09D113/00 

FIELD: composition for corrosion protection of basic constructional materials (steel, concrete).

SUBSTANCE: according to the first variant claimed composition contains (mass %): epoxyorganosilicon oligomer as polymeric film-forming substance 16.0-18.0; butadieneacrylonitrile carboxylate rubber 34.0-36.0; natural fine-grain iron alpha-oxide 24.0-27.0; organosilicon curing agent such as organosilicon amine derivative 12.0-15.0; xylene as solvent 3.3-5.0; microtalc (talcone) 3.0-4.0; synthetic silica 0.7-1.0. Natural fine-grain iron alpha-oxide has low content of silica, aluminum oxide, magnesium oxide, and calcium oxide and not less than 60 mass % of Fe₂O₃. According to the second variant claimed composition contains (mass %): epoxydianic resin as polymeric film-forming substance 14.0-16.0; butadieneacrylonitrile carboxylate rubber 29.0-31.0; natural fine-grain iron alpha-oxide 21.0-31.0; organosilicon curing agent such as organosilicon amine derivative 24.0-25.3; xylene as solvent 3.0-4.0; microtalc (talcone) 3.0-4.0; synthetic silica 0.7-1.0.

EFFECT: composition with increased content of non-volatile components; coating with increased thickness of single layer.
