摘要:
The invention relates to a stable aqueous cream consisting of the following components: (A), which is selected from (A1) C1-C20-alkyl-C2-C6-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.
摘要:
Aqueous emulsions contain the components (A) organosilicon compounds which are selected from (A1) C1-C20-hydrocarbon-C1-C6-alkoxysilanes and (A2) branched organopolysiloxanes containing C1-C6-alkoxy groups, (B) organosilicon compounds which are selected from (B1) C1-C6-alkoxysilanes containing aminoalkyl groups and (B2) branched organosiloxanes containing aminoalkyl groups and (C) an emulsifier. The aqueous emulsions are suitable for imparting water repellency to porous mineral building materials and building coatings and to wood. .
