Aqueous formulations suitable as sealing compounds of adhesives for ceramic tiles
First Claim
1. An aqueous formulation suitable as a sealing compound or an adhesive for ceramic tiles and containing as essential components,A) from 3 to 30% by weight of plastics particles which consist ofa) from 0.1 to 4% by weight of one or more mercaptosilanes of the general formula I ##STR3## where n is from 1 to 8, R1 and R2 are individually hydrogen or C1 -C4 -alkyl, R3, R4 and R5 are individually C1 -C6 -alkyl or C1 -C6 -alkoxy, with the proviso that one or more of the radicals R3 to R5 is alkoxy, andb) ethylenically unsaturated monomers capable of undergoing free radical polymerization, as the residual amount, the polymer having a glass transition temperature of from -60°
- to +40°
C.,B) from 40 to 90% by weight of an inorganic filler,C) an effective amount of an emulsifier,D) from 0 to 15% by weight of an external plasticizer andE) from 5 to 40% by weight of water.

Abstract
Aqueous formulations suitable as sealing compounds or adhesives for ceramic tiles essentially contain
A) from 3 to 30% by weight of plastics particles which consist of
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, R1 and R2 are hydrogen and/or C1 -C4 -alkyl, R3, R4 and R5 are C1 -C6 -alkyl and/or C1 -C6 -alkoxy, with the proviso that one or more of the radicals R3 to R5 is alkoxy, and
b) ethylenically unsaturated monomers capable of undergoing free radical polymerization, as the residual amount,
the polymer having a glass transition temperature of from -60 to +40° C.,
B) from 40 to 90% by weight of an inorganic filler,
C) an effective amount of an emulsifier,
D) from 0 to 15% by weight external plasticizer and
E) from 5 to 40% by weight of water.
