SILICONE RESIN POWDER AND ITS PRODUCTION

Silicone resin powders are obtained by spray drying aqueous colloidal suspensions of organopolysiloxanes which are prepared by adding an alkoxysilane and/or a partial hydrolysate thereof and, if appropriate, mixed with an organo(poly)siloxane which is free of alkoxy groups and contains a maximum of...

Beschreibung
Zusammenfassung:	Silicone resin powders are obtained by spray drying aqueous colloidal suspensions of organopolysiloxanes which are prepared by adding an alkoxysilane and/or a partial hydrolysate thereof and, if appropriate, mixed with an organo(poly)siloxane which is free of alkoxy groups and contains a maximum of 8 siloxane units per molecule, to water in the presence of an emulsifier at a maximum rate of 5 moles of organosilicon compound per hour per liter of water.
