POLYURETHANE-ACRYLIC POLYMER DISPERSIONS AND USE THEREOF Russian patent published in 2015 - IPC C09D5/02 C09D133/06 C09D133/14 C09D175/04 C09D175/14 E04D7/00 E04F15/12 E04F13/02 C08J7/04 

FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous composition for coating roots, facades, floors or vertical exterior coatings. The composition contains at least one acrylic polymer and at least one polyurethane polymer and at least one ethylene-vinyl acetate emulsion in an amount between 15 and 30 wt % of the total weight of the composition, water in an amount between 10 and 40 wt % of the total weight of the composition, wherein at least one acrylic polymer and at least one polyurethane polymer is in the form of a combined product. Also described is a method of coating roofs, facades, floors or vertical exterior coatings using said compositions and use of said compositions as coating for roofs, facades, floors or vertical exterior coatings.

EFFECT: comparable results on resistance to water absorption, permeability, resistance to colour change under the effect of solar radiation and ageing under the effect of heating of the coatings made from a composition containing a combined product with properties of coatings made from polyurethane dispersions.
