Abstract
Aqueous, stiff cream comprising; (A) a silicone compound selected from the group consisting of (A1) a C.sub.1 -C.sub.20 -alkyl-C.sub.2 -C.sub.6 -alkoxysilane and (A2) an alkoxy-containing organopolysiloxane, optionally (B) an organopolysiloxane which, in addition to other organosiloxane units, contains siloxane units which contain radicals bonded via SiC and containing basic nitrogen, with the proviso that the amine number of the organopolysiloxane is at least 0.01, and (C) an emulsifier.
Claims18
An aqueous, stiff cream comprising;
- (A) a silicone compound selected from the group consisting of
- (A1) a C.sub.1 -C.sub.20 -alkyl-C.sub.2 -C.sub.6 -alkoxysilane and
- (A2) a alkoxy-containing organopolysiloxane,
- (B) optionally an organopolysiloxane which, in addition to other organosiloxane units, contains siloxane units which contain radicals bonded via SiC and containing basic nitrogen, with the proviso that the amine number of the organopolysiloxane is at least 0.01, and
- (C) an emulsifier,
- wherein the total amount of components (A) and (B) is at least 65% by weight based on the weight of said stiff cream, and
- wherein the stiffness of said stiff cream is such that when applied to a vertical concrete surface in a thickness of 1 mm by spraying or knife coating, the cream will not run down the vertical concrete by more than 5 cm before it has been completely absorbed by the concrete.
