Abstract
Compositions for the impregnation of mineral building materials, which comprise (A) salts of organic or inorganic acids and an organopolysiloxane siloxane or mixture of organopolysiloxanes containing SiC-bonded radicals containing basic nitrogen, in amounts of at least 0.5% by weight, based on the weight of the organopolysiloxane, optionally (B) an organosilicon compound containing basic nitrogen, in amounts of 0 to 0.5% by weight, based on the weight of the organosilicon compound, and (C) a fluorine-containing organic or organosilicon compound.
Claims9
A composition for the impregnation of mineral building materials, which comprises
- (A) salts obtained by the reaction of
- (i) organic or inorganic acids, with
- (ii) an organopolysiloxane or mixture of organosiloxanes, wherein the organosiloxane(s) contain SiC-bonded radicals containing basic nitrogen, in amounts of at least 0.5% by weight, based on the weight of the organopolysiloxane(s),
- (B) optionally an organosilicon compound containing basic nitrogen, in amounts of 0% to 0.5% by weight, based on the weight of the organosilicon compound, and
- (C) a fluorine-containing organic or organosilicon compound.
