FIELD: building materials. ^ SUBSTANCE: invention relates to a method for preparing the coating composition based on modified epoxy resin used in protection of building constructions, for example, as a component for pouring floorings. The composition comprises the following ratio of components, wt.-%: epoxy diane resin, 55.0-63.0; amine hardening agent as a mixture of isophoronediamine, 13.0-20.3, and one of amine taken among methaxilylenediamine, 7.0-9.0, or diethylenetriamine, 5.0-6.0, or triethylenetetraamine, 5.5-6.5 and tris-(dimethylaminomethyl)phenol, 2.0-2.7, as adduct with laprolat-803, 6.5-10.5, and mixture of dioxane alcohols and their high-molecular esters (EDOS). Laprolat-803 represents polyoxypropylenetriol tricyclocarbonate propyl ester. Invention provides hardness and wear-resistance of coating. ^ EFFECT: improved and valuable properties of composition. ^ 2 tbl, 7 ex |
