Abstract

Aqueous formulations suitable as sealing compounds or adhesives for ceramic tiles essentially contain PA0 A) from 3 to 30% by weight of plastics particles which consist of PA1 a) from 0.1 to 4% by weight of one or more mercaptosilanes of the general formula I ##STR1## where n is from 1 to 8, R.sup.1 and R.sup.2 are hydrogen and/or C.sub.1 -C.sub.4 -alkyl, R.sup.3, R.sup.4 and R.sup.5 are C.sub.1 -C.sub.6 -alkyl and/or C.sub.1 -C.sub.6 -alkoxy, with the proviso that one or more of the radicals R.sup.3 to R.sup.5 is alkoxy, and PA1 b) ethylenically unsaturated monomers capable of undergoing free radical polymerization, as the residual amount, PA0 the polymer having a glass transition temperature of from -60 to +40.degree. C., PA0 B) from 40 to 90% by weight of an inorganic filler, PA0 C) an effective amount of an emulsifier, PA0 D) from 0 to 15% by weight external plasticizer and PA0 E) from 5 to 40% by weight of water.
