Patent ID: 8907011

Claim:
An aqueous dispersion of organosilicon compounds, comprising: (A) a mixture consisting essentially of inorganic filler (B) and siloxane (C) containing units of the formula (I) R a (R 1 O) b SiO (4-a-b)/2 (I) in which R are the same or different and are hydrogen or a monovalent, SiC-bonded, optionally substituted hydrocarbyl radical, R 1 are the same or different and are hydrogen, or a monovalent, optionally substituted hydrocarbyl radical, a is 0, 1, 2 or 3, and b is 0, 1, 2 or 3, with the proviso that the sum of a and b is less than or equal to 3, and the siloxane (C) has a viscosity at 25° C. of 5 to 1,000,000 mPas, the mixture (A) having a viscosity of 10 to 10,000,000 mPas at 25° C., and filler (B) comprising silica, (D) silanes of the formula R 3 c R 2 d Si(OR 4 ) 4-c-d (II) in which R 2 are the same or different and denote monovalent, SiC-bonded, optionally substituted hydrocarbyl radicals having 1 to 3 carbon atoms, R 3 are the same or different and denote monovalent, SiC-bonded, optionally substituted hydrocarbyl radicals having at least 4 carbon atoms, which may be interrupted by heteroatoms and/or carbonyl groups, R 4 are the same or different and denote monovalent, optionally substituted hydrocarbyl radicals or hydrogen, c is 1, 2 or 3, and d is 0, 1 or 2, with the proviso that the sum of c and d is 1, 2 or 3, and/or partial hydrolysates thereof, (E) optionally organopolysiloxanes, (F) emulsifier, (G) water, and (H) optionally further substances.
