Aqueous creams of organosilicon compounds for hydrophobicizing building materials

摘要

Aqueous, stiff cream comprising;PP(A) a silicone compound selected from the group consisting ofPP (A1) a C. sub.1 -C.sub.20 - alkyl-C.sub.2 -C.sub.6 -alkoxysilane and P P(A2) an alkoxy-containing organopolysiloxane, optionallyP P(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 PP(C) an emulsifier.
