ANTICORROSION PROTECTIVE COATING BASED ON MODIFIED AMINE CURING AGENT Russian patent published in 2025 - IPC C09D163/00 C09D5/08 C08L79/02 C07C211/27 

FIELD: chemistry.

SUBSTANCE: invention relates to epoxy coatings used as a base for anticorrosion coatings and repair compositions. Disclosed is an epoxy composition for producing an anti-corrosion protective coating, consisting of component A, including epoxy resin, organic additives and mineral fillers, and component B, which includes amine curing agents, mixtures thereof and organic additives, characterized by that the components additionally contain as organic additives electrically conducting polymers: products of oxidative polycondensation of aniline for component B and products of oxidative polycondensation of N-methylaniline for component A, wherein ratio of component A and component B is 100/3 or 4/1 parts by weight.

EFFECT: higher strength and protective properties of coating, wherein the obtained coatings have high adhesion to the test plates, have less susceptibility to cracking and cavitation action, have high thermal conductivity compared to existing counterparts.
