Beschreibung
Zusammenfassung:	FIELD: varnish-and-paint industry. ^ SUBSTANCE: object of invention is to remove old coatings without use of mechanical cleaning means both in industry and in household. Composition according to invention contains dichloromethane, acetic acid, solid paraffin, and copolymer, in particular copolymer A-25. Additionally, as loosening agent, sodium acetate is used at weight ratio to acetic acid 0.6:1 and, as thickener, aqueous solution sodium-carboxymethylcellulose. ^ EFFECT: reduced toxicity while preserving washing effect of composition, and lowered cost due to more accessible and effective components as functional additives. ^ 2 tbl
