Aqueous creams of organosilicon compounds for waterproofing building materials

摘要

Stable aqueous cream, containing (A) (1-20C alkyl)-(2-6C alkoxy)-silanes (A1) and/or alkoxy group-containing organopolysiloxanes (A2), optionally (B) organopolysiloxanes with an amine number of at least 0.01, containing Si-C linked groups with basic nitrogen in addition to other organosiloxane units, and (C) emulsifier. Also claimed is a process for the production of this cream, by (a) making a mobile aqueous emulsion from part of (A) and (B) and most of (C), and then (b) mixing in the rest of (A) and optionally (B) to a creamy consistency.
