POLYMERIC PROTECTIVE BARRIER COATING Russian patent published in 2007 - IPC C09D163/02 C09D5/08 

FIELD: polymer materials.

SUBSTANCE: invention provides composition for producing polymeric protective coatings on various surfaces, including metal, concrete surfaces, structural members of conduits, metal units and assemblies in different technical areas, said coatings serving as barriers against attacks of various-type corrosive media. Composition contains following components, wt %: epoxide dian resin, 33.5-41.0; dibutyl phthalate and/or aliphatic epoxide resin DEG-1, 2.5-10.0; polyethylene-polyamine hardener, 4.0-6.5; plate filler in the form of andesite basalt scales with scale thickness 0.2 to 7.0 μm, 42.5-50.0, and, if necessary, Aerosil, 0-6.0, and/or organic solvent, 0-17.5.

EFFECT: reduced toxicity of composition, simplified preparation thereof, reduced barrier properties thereof, and extended functional destination.
