Abstract: The present invention relates to the use of compositions comprising at least one aqueous polymer dispersion wherein the polymer has carbonyl or oxirane groups (component a)) and at least one compound with at least two NH2 groups per molecule as sealing or coating compositions, especially for substrates with a hydrophobic surface. The present invention further relates to coating compositions containing such binder formulations.

Abstract: A process for preparing aqueous polymer dispersions comprises first of all subjecting ethylenically unsaturated monomers to free-radical aqueous emulsion polymerization to prepare an aqueous dispersion of a polymer 1 having a glass transition temperature Tg1, then dissolving further, comparatively hard monomers in the dispersed particles of the polymer 1, and subsequently carrying out free-radical polymerization of the monomers dissolved in the particles.

Abstract: Aqueous polymer preparations containing dispersions of (i) a hydrophilic polymer (P1) based essentially on ethylenic monomers with a water solubility of 10-100 g/l and (ii) a hydrophobic polymer (P2) based on monomers with a water solubility of less than 10 g/l, in which the glass transition temperatures of P1 and P2 differ by less than 10 K. Aqueous preparations containing (i) hydrophilic polymer particles (P1) in the form of an aqueous dispersion based on ethylenic monomers (M) comprising 20-100 wt% unsaturated monomer(s) (M1) with a water solubility (at 25 deg C/1 bar) of 10-100 g/l, 0-80 wt% unsaturated monomer(s) (M2) with a water solubility of less than 10 g/l and 0-20 wt% other monomer(s) (M3) and (ii) hydrophobic polymer particles (P2) as an aqueous dispersion based on unsaturated monomers (M') comprising 0-20 wt% monomer(s) (M1') with a water solubility of 10-100 g/l, 80-100 wt% monomer(s) (M2') with a water solubility of less than 10 g/l and 0-20 wt% other monomer(s) (M3'), in which the glass transition temperature (Tg1) of polymer (P1) differs from that of (P2) (Tg2) by less than 10 K.

Abstract: An aqueous composition (I) containing a copolymer (II), formed of ethylenically unsaturated monomers, as a film forming component, is used for coating mineral based molded articles. The copolymer (II) has a glass transition temperature of 25-80 degrees C and the monomer contains 0.2-5.0 wt.% itaconic acid. Independent claims are included for: (i) the production of coated, mineral molded articles by application of (I) onto at least one surface of the article and drying; and (ii) the resulting coated, molded article.
