A range of two-component epoxy coating materials has been developed to successfully address the issue of corrosion protection for metal surfaces and transport vehicles. This includes primer coatings for protective protection of metal structures for railway, marine, and river transport; primers for priming black metal surfaces that have corroded and are used in industrial atmospheres, including those anticipated for use in acidic and alkaline environments; enamels for reliable corrosion protection of pre-corroded metal surfaces with a rust layer thickness of up to 100 microns, enamel alloys of steel, magnesium, aluminum, copper, and titanium, as well as environmentally friendly epoxy enamel with low content of volatile organic compounds for the protection of large metal structures from corrosion. A technology has been developed and the physical-mechanical and chemical properties of the obtained materials and coatings have been investigated. Modification of the enamel composition with low solvent content by detonation nanodiamond nanoparticles has been carried out, and an increase in the hardness of the coatings has been established with an optimal content of nanoparticles in the hybrid nanocomposite material.
