The present invention relates to curable compositions comprising a) at least one organic polymer selected from polyurethanes, polyesters and polyethers, having at least one end group of the general formula (I) -A n -R-SiXYZ (I), in which A is a divalent linking unit selected from the amide, carbamate, urea, imino, carboxylate, carbamoyl, amidino, carbonate, sulphonate and sulphinate group and from the oxygen atom and nitrogen atom, and R is a divalent hydrocarbon radical having 1 to 12 C atoms that optionally contains a heteroatom, and X, Y and Z each independently of one another are C 1 -C 8 alkyl, C 1 -C 8 alkoxy or C 1 -C 8 acyloxy radicals, with at least one of the radicals X, Y and Z being a C 1 -C 8 alkoxy or C 1 -C 8 acyloxy group, and n is 0 or 1; and b) a filler mixture comprising at least one alkaline earth metal carbonate and at least one silicate-based filler, and also to the use thereof as an adhesive, sealant or coating material, more particularly for the adhesive bonding of tiles, including glass tiles, glass or ceramic mosaics or natural-stone slabs, and also for the sealing of substrates and walls against water penetration. |
