COMPOSITION FOR CONCRETE SURFACES IMPREGNATION Russian patent published in 2018 - IPC C09D5/02 C09D163/00 C09D125/02 C09D123/34 C04B41/48 

FIELD: chemistry.

SUBSTANCE: invention relates to the chemistry of polymers, in particular to water-soluble impregnating compositions used for concrete surfaces impregnation to increase the strength and lasting properties of impregnated concrete surfaces. Composition comprises an aqueous solution of an epoxy dimethyl hydantoin resin and an aminophenol hardener, modifiers in the form of 10 % solution of chlorosulfonated polyethylene and 10 % solution of petroleum resin in the active diluent of epoxy resins UP-616. If necessary, the composition additionally comprises an iron oxide pigment.

EFFECT: introduction of modifier solutions into the composition of solutions in the active diluent of epoxy resins UP-616 allows to increase the depth of concrete impregnation, the adhesion strength of the composition to concrete, reduce brittleness, increase the strength and lasting properties of impregnated concrete surfaces.
