STABLE, FINELY DIVIDED AQUEOUS ONE-COMPONENT SILICONE CATALYSTS, PROCESS FOR THEIR PREPARATION AND THEIR USE

摘要

The present patent application relates to stable, finely-dispersed, aqueous single-component silicone catalysts which have been obtained by combining a silicone dispersion which is free to essentially free of lower monohydric alcohols and has been prepared in a conventional manner in the presence of long-chain liquid alcohols having 6 to 18 carbon atoms and with the use of known epoxyamine prepolymers as emulsifiers with a separately prepared, conventional nonionic or cationic dispersion of organometallic compounds. In addition, a process for the preparation of this emulsion and the use thereof are described. The catalysts according to the invention are distinguished by not having a flashpoint or having a flashpoint above 65 DEG C. and nevertheless having excellent stability, in particular mechanical stability.
