FIELD: chemistry.SUBSTANCE: invention relates to water-soluble systems based on epoxy resins. Claimed are two-component compositions for coating, including epoxy resins B, which contain at least one epoxy group per molecule, and adducts A of epoxy resins A1, containing at least one epoxy group per molecule, and multifunctional A2 acids, containing at least two hydrogen-containing acid groups per molecule, in which multifunctional acids A2 represent additional products of phosphoric acid and epoxyfunctional compounds A21, which contain at least one epoxy group per molecule, where epoxy resins A1 and epoxy resins A21 represent bisphenol A derivatives, as well as method of their obtaining and method of their application in substrate coating.EFFECT: claimed compositions make it possible to obtain coatings, possessing hardness, mechanical and chemical stability, suitable for application on floors.7 cl, 2 tbl, 5 ex |
