Publication number: 20180244909Abstract: Highly condensed silicon resins are obtained by a three step continuous procedure without the use of organic solvent, by preliminarily forming a partial alkoxylate by reacting a chlorosilane with alcohol containing no or a minimal amount of water, feeding the partial alkoxylate to a reaction column to form a silicone resin of low degree of condensation, and further condensing the silicone resin intermediate thus formed to produce a silicone resin product.Type: ApplicationFiled: February 18, 2016Publication date: August 30, 2018Applicant: Wacker Chemie AGInventors: Hans-Peter WEITZEL, Ulf DIETRICH, Peter FRITZE, Klas SORGER
