WATER-DISPERSION COMPOSITION Russian patent published in 2009 - IPC C09D5/02 C09D133/04 C09D133/08 

FIELD: chemistry.

SUBSTANCE: water-dispersion composition for coating includes acrylic film-forming material - 47-49%, water-acrylic dispersion stabilised with anion system of emulsifier "Finndisp", thinner - silicone dioxide "Aerosil A-300", organic derivative of smectite clays "Benton LT" and acrylic latex "Polyphob TR-117" with dry solids content 40%, pigments, calcite filler, antifoamer - mineral oil - mixture of the unsaturated fatty acids esters with hydrophobic "Foamex K-3" or dispersion of the hydrophobic wax and ester in mineral oil "Serdas 7005", coalescent - esteroalcohol 2,2,4-trimethyl-1,3-pentadiol monoisobutirate "Texanol" and butyldiglicole, dispersant - "Orotan 731K", conservant - solution of isothiazoline derivatives: 1,2-hydroxy-5,8,11-trioxadodecane, 1,3-bis (hydroxydimethyl)-carbamide, 1,6-hydroxy-2,5-dioxahexane "Parmetol A-26", pH regulator - 25% water ammonia solution, antifreeze - ethyleneglycol, surfactant -polyoxymethylene ether of alkylphenol and 75% water solution of anion wetting surfactant agent "Nuosperse 2006", hydrophobic additive - 29-31% wax emulsion "Aquacer -535" and solvent - water at the determined components ratio. The claimed water-dispersion composition for coatings has the film rinsability index 0.7-1.4 g/m².

EFFECT: enhancing of composition performance.
