Abstract: Method of coating mineral moldings with film-forming aqueous formulations involves applying first coat(s) containing copolymer(s) (P1) as binder and inorganic pigment(s); optionally drying; then applying coat(s) containing copolymer(s) (P2) as binder and optionally inorganic pigment, in which copolymers P1 and P2 consist of (A) vinyl-aromatic(s) (A1) and/or 1-4 C alkyl methacrylate(s) (A2), (B) 1-12 C alkyl ester(s) (B1) of alpha , beta -ethylenically unsaturated carboxylic acids, other than (A2), and/or vinyl esters (B2) of aliphatic carboxylic acids and optionally (C) other alpha , beta -ethylenically unsaturated monomer(s). The novelty is that P1 and P2 consist of the same monomers A and B and the pigment volume concentration (PVC) of the first formulation is at least 10 times higher than that of the second. Independent claims are also included for (a) the coating formulation system; and (b) mineral moldings coated in this way.

Abstract: Surprisingly aqueous preparations containing a copolymer P as completely or largely cross linked constituent comprising methacrylic acid alkyl esters, in which the bulk of methyl methacrylate monomer varies give coatings of gloss with increased stability over time. The coatings show good adhesions to mineral substrates and guarantee good protection against efflorescence. The use of an aqueous film forming preparation, for coating a mineral molded body, containing at least one copolymer P as film forming component dispersed in the preparation and ethylenically unsaturated monomers M is new. The monomer M comprises (wt. %): (i) 70-99 of at least one methacrylic acid ester with a 1-10C alkanol and (ii) 0.1-30 of at least one of different ethylenically unsaturated monomers, in which at least 50 wt. % of monomer M comprises methacrylic acid methyl ester, and at most 1 wt. % of monomer M contains two or more ethylenically unsaturated double bonds. Independent claims are included for: (1) A process for coating a mineral molded body with at least one aqueous film forming preparation; (2) a mineral molded body.

Abstract: A process for preventing efflorescence on mineral substrates (I) comprises treating the surface of (I) with an aq. prepn. contg., as principal component, an aq. dispersion of a polymer (II) contg. 0.1-5 wt.% chemically-bonded organo-Si cpd. (III) which forms a silanol by hydrolysis. Pref., (II) is prepd. by emulsion polymerisation of a mixt. of 95-99.5 wt.% n-butyl or 2-ethylhexyl acrylate, ethyl or methyl methacrylate and/or styrene (at least 2 of these monomers) and 0.5-5 wt.% (meth)acrylic acid, (meth)acrylamide or vinylsulphonic acid, in the presence of (III), esp. e.g. vinyltrimethoxysilane, gamma-methacryloxypropyl- trimethoxysilane, 3-mercaptopropyl- trimethoxysilane, gamma-glycidoxypropyl- trimethoxysilane (IIIA). USE/ADVANTAGE - Used esp. for preventing efflorescence on concrete roof tiles, bricks, etc.. The process provides a highly weather-resistant coating which affords excellent protection against lime efflorescence; the coating does not become sticky at elevated temp. and therefore does not attract dirt in hot weather.
