PRIMING COMPOSITION Russian patent published in 2008 - IPC C09D167/08 C09D5/06 C09D5/12 

FIELD: protecting materials.

SUBSTANCE: invention relates to priming compositions used for anticorrosive covers applied on surface of mainly ferrous metals in machine engineering, and woody and other materials. The priming composition comprises lacquer GF-01, red pigment, siccative, solvent, chalk of sort M-5 and lecithin as a disperser, siccative NF-1 as a siccative, and slime after dry scrubbing in electric steel melting production of the following chemical composition, wt.-%: SiO₂, 7.76; phosphorus (P), 0.041; chrome (Cr) total, 1.0; Al₂O₃, 0.93; TiO₂, 0.099; MnO, 2.29; CaO, 21.3; MgO, 24.5; FeO, 3.91; Fe₂O₃, 32.02; CaF₂, 5.26; CaO (incompletely burned material), 0.89 in the following granulometric composition of slime, %: below 20 mcm, 15; from 20 to 25 mcm, 60, and from 25 to 100 mcm, 25. Invention provides decreasing cost and enhancing exploitation parameters of the priming in coating the broad spectrum of surfaces in machine engineering and building.

EFFECT: improved and valuable properties of priming composition.
