AQUEOUS-DISPERSION COMPOSITION Russian patent published in 2003 - IPC

FIELD: paint and varnish compositions. SUBSTANCE: invention relates to acrylic priming for aqueous-dispersions. Composition comprises film-forming agent an aqueous anionic dispersion of copolymer based on acrylic acid ester and carboxyl-containing monomer "Emular-272" or non-plasticized polymeric dispersion of copolymer of n-butyl acrylate and styrene "Finndisp A-10", thickening agent - copolymer of (meth)acrylic monomers "Akremos" or "Reolat - 420", or acrylurethane thickening agent of associative type "Polifob", preserving addition solution of derivatives of isothiazolone, coalescing addition complex esteroalcohol 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and/or butyl diglycol (diethylene glycol monobutyl ester), foam suppressor addition tributyl phosphate or highly aromatic mineral oil "Foameks", antifreeze ethylene glycol or propylene glycol, medium pH stabilizing agent 25% ammonium aqueous solution and water. Composition comprises additionally antiseptic addition synergetic mixture of aromatic and heterocyclic algicide and fungicide active additions of sort "Parmetol DF-19" or an aqueous preparation based on dairon, carbendacim and octylisothiazolone of sort "Preventol TP SP 80036". Combination of components taken in the definite ratio allows preparing priming providing protection against mold fungi, decaying, atmospheric and other hazard effects. Composition is designated for priming and impregnation of facing walls of buildings and apartments, among them with enhanced moisture by concrete, gas concrete, brick, stone, plastered surfaces, by surfaces made of gypsum cardboard, splint-slab and wood- -fiber plates and wood surfaces before carrying out the painting works. EFFECT: valuable properties of composition. 3 cl, 2 tbl, 12 ex
