ANTICORROSION COATING COMPOSITION Russian patent published in 2015 - IPC C09D5/08 C09D5/10 C09D163/02 

FIELD: chemistry.

SUBSTANCE: anticorrosion coating composition contains an epoxide oligomer, polyethylene polyamine, zinc powder, a solvent - mixture of xylene and butanol in weight ratio of 1:1 and a target additive. The target additive is glycidoxypropyltrimethoxysilane. The anticorrosion composition contains components in the following ratio, wt %: epoxide oligomer 25.7, polyethylene polyamine 2.3, zinc powder 42, said mixture of xylene and butanol 29.79-29.84, glycidoxypropyltrimethoxysilane 0.16-0.21.

EFFECT: invention simplifies implementation and reduces power consumption when preparing the anticorrosion coating composition, improves corrosion resistance of steel by reducing the electrochemical potential of steel compared to that of prototype steel with improved physical and mechanical properties of coatings.
