Patent

CA 2164679

Disclosed are water-based organopolysiloxane-containing compositions which are essentially free from organic solvents, have a flashpoint above 80°C and essentially liberate no alcohols by hydrolysis on dilution with water. The organopolysiloxane-containing compositions are obtainable by mixing water-soluble aminoalkylalkoxysilanes with alkyltrialkoxy-silanes, dialkyldialkoxysilanes or mixtures thereof which are not water-soluble, adding water to the mixture, adjusting the pH of the reaction mixture to a value of between 1 and 8 and removing the alcohol already present or formed during the reaction. A process for the preparation of the organopolysiloxane-containing compositions and their use are also disclosed.
