FIELD: chemistry.
SUBSTANCE: epoxy composition is intended for obtaining anti-corrosion coatings on products and reservoirs from concrete, reinforced concrete, metallic constructions. Composition includes following components, with their ratio, wt %: 47.4-54.4 of epoxy-diane resin ED-20, 2.8-4.3 of modifier, 19.6-27.0 of solvent, 21.7-22.8 of amine hardener. As modifier composition contains polyisocyanate based on 4,4'-diphenylmethandiisocyanate. As solvent composition contains solvent R-4. As hardener composition contains aromatic polyamine "Aramine".
EFFECT: increase of water-resistance and resistance of composition to impact of acids and alkalis.
