FIELD: material engineering.
SUBSTANCE: present invention relates to the field of creating two-component cold-curing epoxy compositions that are widely used. A two-component cold-curing epoxy composition containing an epoxy base comprising (wt. %) epoxy resin (75.0-95.0) and an active diluent: aliphatic glycidyl ether (5.0-25.0), and a curing amine system containing (wt. %) isoforondiamine (45.0-70.0) and a cycloaliphatic modified adduct (30.0-55.0). The ratio of the epoxy base and the curing system in the composition is, wt. %: 100:(26-37). The curing amine system may additionally contain polyethyramine.
EFFECT: improved technological characteristics of the composition, which simplifies the process of obtaining it and provides the possibility of its use during on-site repair work, outside construction sites, and also provides the formation of uniform reliable adhesion of the cured composition to concrete, improved protection of repaired and restored structures from moisture and provides the possibility of reliable operation in a wider temperature range.
