Publication number: 20130309498Abstract: A granulated product comprises a liquid organosilicon compound supported on a particulate carrier which is agglomerated into granules by a binder. A process for the production of a granulated product comprises depositing an organosilicon compound and a binder in a liquid state on a particulate carrier and subjecting the carrier thus treated to conditions in which the binder is solidified, thereby agglomerating carrier particles into granules. The particulate carrier is anhydrous sodium sulfate of mean particle size 1 to 40 ?m.Type: ApplicationFiled: December 9, 2011Publication date: November 21, 2013Applicant: Dow Corning CorporationInventors: Sung-Hsuen Chao, Alain Hilberer, Jean-Paul Lecomte, Stephane Lecomte, Marc Thibaut
