摘要:
The invention relates to the use of a composition comprising a C1 to C6 alkanol and a carboxylic acid ester of formula (I) wherein R1 is selected from a C1 to C6 alkyl, which may be unsubstituted or substituted by OH or F, and —X21—[O—X22]n—H; R2 is selected from a C1 to C6 alkyl, which may be unsubstituted or substituted by OH or F, and —X21—[O—X22]n—H; X21, X22 are independently selected from C1 to C6 alkandiyl, which may be unsubstituted or substituted by OH or F; n is an integer from 1 to 5. wherein, the C1 to C6 alkanol and the carboxylic acid ester are selected so as to form an azeotropic mixture and are present in an amount from 20% by weight below to 20% by weight above such azeotropic mixture.
摘要:
The present invention relates to latex paints, which contain a) a multistage carboxylated polymer latex binder obtainable by multistage aqueous emulsion polymerisation of a monomer composition M consisting of at least one non-ionic monomer M1, which is selected from C1-C20-alkyl esters of acrylic acid, C1-C20-alkylesters of methacrylic acid, and vinyl aromatic monomers; one or more monoethylenically unsaturated monomers M2, which are selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, and optionally one or more non-ionic monomers M3, which are different from monomers M1; where in at least one stage, the relative amount of monomers M2 in added in this stage is at least 6% by weight, based on the total amount of monomers added in said stage, the total amount of monomers M2 being from 0.05 to 5% by weight, based on the total amount of the monomer composition M; b) a titanium dioxide pigment; c) a polymeric dispersant PD which is selected from homo and copolymers of monomers M4, which are selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, where the monomers M4 make up at least 85% of the monomers forming the polymeric dispersant; and d) an associative thickener polymer.
