POLYMER COMPOSITION FOR ANTICORROSION OIL-RESISTANT COATING Russian patent published in 2007 - IPC C09D109/06 C09D157/02 C09D5/08 

FIELD: polymer materials and corrosion protection.

SUBSTANCE: invention relates to anticorrosive protection of articles, units, and constructions made of ferrous metals, concrete, and reinforced concrete operated under corrosive aqueous and oil-containing media conditions. Composition contains butadiene-styrene thermoplastic elastomer (DST-30R-01) as film-forming component, indene-cumaron resin and epoxide dian resin (ED-20) as adhesive additives, phenyl-2-naphthylamine as amine-type antioxidant, xylene and/or toluene as organic solvent, polymethylsiloxane liquid (PMS-200) as spreading agent, and mixture of cobalt, manganese, and lead octoates as thixotropic additive in the form of 45-55% solution in white spirit or petroleum solvent Nefras C4-155/200, wherein mass percentage of lead is 15.0-15.5% and summary mass percentage of cobalt and manganese is 2.0-2.4%. Composition is thixotropic so that coating with thickness of nondrip wet layer 1.0-1.3 mm may be applied.

EFFECT: increased oil resistance in media of water-saturated petroleum products.
