    Abstract: A concrete roof tile is coated with an unfilled or aggregate- and/or pigment-filled film of a copolymer containing (a) from 0.03 to 2% by weight of tin in the form of a polymerizable organotin compound (b) from 0.5 to 5% by weight of (meth)acrylic acid, (meth)acrylamide and/or vinylsulfonic acid and (c) from 0.1 to 5% by weight of carbonyl-containing monomers crosslinked with certain dicarboxodihydrazides, besides (d) at least two (meth)acrylic esters of C1-C8alkanols and/or styrene as copolymerized units in such an amount and such mixing ratios that the copolymer has a glass transition temperature of -15 to +10 DEG C. prior to crosslinking.

    Abstract: A concrete tile (I) is claimed, which is coated with a copolymer (A) with Tg -25 to +30 deg.C, derived from (a) 0.1-10 wt.% monomer of formula R1CH=CR2-CO-X-R3-Z-CHR4R5 (III), (b) 85-99.9 wt.% at least 2 monomers of the type (1-24C alkyl) (meth)acrylates, vinyl esters of 1-20C carboxylic acids, up to 20C vinylaromatics, 3-6C unsatd. nitriles, vinyl halides and/or 2-8C non-aromatic hydrocarbons with olefinic double bond(s), and (c) 0-10 wt.% other Sn-free comonomers; R1, R2 = H or 1-4C alkyl; R3 = 1-20C bridging gp.; R4 = -COR6, -COOR6 or CN; R5 = H, -COR9, -COOR9 or CN; X = O or NR7; Z = single bond, CH2, O, NR8 or -OCO-; (with R6-R9 = H, or 1-12C alkyl, aryl, alkaryl or aralkyl). Also claimed is a process for the prodn. of (I), by application of an aq. prepn. contg. (A) to at least one surface of the green concrete, and drying the prepn. by hardening the concrete. More specifically, monomer (a) is acetylacetoxyethyl (meth)acrylate, acetylacetoxybutyl (meth)acrylate, cyanoacetoxyethyl (meth)acrylate, 1,1-dibenzoyl-2-(meth)acrylamidoethane, 1-benzoyl-1-acetyl-2- (meth)acrylamidoethane, or ethyl alpha-benzoyl-beta-(meth) acrylamidopropionate, and (b) are vinylaromatics or (1-8C alkyl) (meth)acrylates; (I) is coated with a prepn. contg. copolymer (A) and up to 450 wt.% mineral additives (B) and/or colour pigments (C) (w.r.t. amt. of A); another layer of the aq. prepn. is applied to the hardened tile and dried; the amt. of prepn. used is such that the total amt. of dry coating is 50-500 g/m2.

    Abstract: The use of an aqueous polymer dispersion for modifying cement bonded mineral coatings for concrete mold bodies. The polymer comprises: (A) a polymer P in the form of ethylenic unsaturated polymer particles with a glass transition temperature of -20 - + 80 C; and (B) an emulsifier for stabilizing the polymer particles. (A) comprises: (i) 90 - 99.9 wt. % hydrophobic, monoethylenic unsaturated monomer(s) (M1) from styrene, butadiene, 1 - 4 C alkylester of methacrylic acid and 2 - 12 C alkylester of acrylic acid; and (ii) 0.1 - 10 wt. % hydrophilic, monoethylenic unsaturated monomer (M2) comprising up to 2 wt. %, based on the total amount of monomer of a monoethylenic unsaturated monomer(s) containing an acid group (M2a) and/or up to 10 weight. % thereof different hydrophilic monomer (M2b). (B) comprises: (a) the salt of a sulfuric acid half ester of an alkoxylated alcohol, containing a 4 - 20 C alkyl chain(s) (salt a); and (b) an alkoxylated alcohol containing a 4 - 20 C alkyl chain(s) (compound b). An independent claim is also included for the preparation of a mineral coated concrete roofing slabs, comprising: (i) conventional manufacture of the uncoated roofing slabs blank; (ii) application to the damp blank of a cement bonded mineral mixture comprising the novel aqueous polymer dispersion, inorganic pigment dye, conventional additives, cement and water; and (iii) removal of the roofing product.
