Fired clay moldings are hydrophobicized by applying a long chain alkyl-substituted alkoxysilane or hydrolysate thereof having up to 5 silicon atoms, and an alkoxy-functional silicone resin. The moldings, which may be roof tiles, are hydrophobicized to a significant depth, without discoloration.

Method for the hydrophobic impregnation of fired ceramic molded bodies

The invention relates to a stable aqueous cream consisting of the following components: (A), which is selected from (A1) C -C -alkyl-C -C -alkoxysilanes and (A2) organopolysiloxane containing alkoxy groups; (C) an emulsifier; and (D) an organic solvent. The stable aqueous cream is suitable for the hydrophobic impregnation or priming of mineral building materials.

The invention relates to a process for stabilizing organopolysiloxanes which contain phosphazenes and/or their reaction products which promote the condensation and/or equilibration of organopolysiloxanes. To stabilize any previously known organopolysiloxanes which contain phosphazenes and/or their reaction products against re-arrangements and also molecular weight changes and viscosity changes resulting therefrom, it is proposed that the said phosphorus compounds be brought into contact with at least one non-basic, solid adsorbent.
