POLYMER COMPOSITION FOR ANTI-CORROSION COATING Russian patent published in 2019 - IPC C09D5/08 C09D163/00 C04B20/10 

FIELD: technological processes.

SUBSTANCE: invention relates to polymer industry and can be used as a coating for protection from corrosion of concrete and reinforced concrete structures, for creation of wear-resistant self-leveling floors, as a sealing material, for decorative finishing of concrete surfaces. Composition contains components at the following ratio, weight parts: transparent epoxide compound Ethal-27HT/12HT – 100; microcalcite with particle size 0.5–1 mm – 72–120; microcalcite with particles of fraction less than 0.2 mm – 112–80. Epoxy compound Ethal-27HT/12HT is formed by combination of component A, which is a colorless transparent low-viscosity epoxy resin, and component B, which is low-viscosity hardener of ETHAL type, with ratio of 81.6:18.4 pts.wt.

EFFECT: improved strength characteristics when compressing and bending polymer composition.
