COATING COMPOSITION Russian patent published in 2025 - IPC C09D163/02 C09D5/08 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of film-forming cold-curing epoxy coatings and can be used as a protective anticorrosion coating for articles made from concrete, reinforced concrete and metal structures. Disclosed is a coating composition containing (wt.pts.): epoxy diane resin “ЭД-20” (100), polyisocyanate based on 4,4'-diphenylmethane diisocyanate (30-50), dimorpholine diethyl ether (0.8-1.5) and an organic solvent xylene or toluene (65-150).

EFFECT: disclosed composition is single-component, wherein basic physical and mechanical properties of said coating obtained on the basis of the claimed single-component composition, such as adhesion, water absorption and resistance to aggressive media, are similar to the properties of the coating obtained on the basis of double-component compositions.
