Two-component painting system for road fixtures

Abstract

The utility model relates to the field of protective and marking coatings for road infrastructure, and in particular to painting systems for road structures. The utility model is used to form coatings on concrete, cement, asphalt, metal, and other surfaces of roads, bridges, viaducts, tunnels, ramps, crosswalks, bike lanes, and other elements of road infrastructure. The two-component coating system for road infrastructure comprises a primer formulation for forming a base coat on the surface of a road structure and a paint formulation for forming a topcoat over the base coat. According to the utility model, the primer composition includes polyurethane resins in an amount of 40 to 55 wt. %, bentonite in an amount of 0.2 to 0.6 wt. %, a dispersing agent in an amount of 2 to 4 wt. %, butyl acetate in an amount of 8 to 12 wt. %, titanium dioxide in an amount of 8 to 12 wt. %, and a mineral filler in an amount of 24 to 26 wt. % relative to the total amount of the primer composition. The paint composition includes acrylic resin in an amount of 25 to 30 wt. %, mineral turpentine in an amount of 15 to 17 wt. %, titanium dioxide in an amount of 14 to 16 wt. %, calcium carbonate in an amount of 28 to 32 wt. %, a dispersing agent in an amount of 0.8 to 1.2 wt. %, bentonite in an amount of 0.3 to 0.7 wt. %, and at least one processing additive in an amount sufficient to make up 100 wt. % of the paint composition.
