  • Method for producing silicone multi-layer composites
    Patent number: 10518455
    Abstract: Multilayer silicone composites with precise thickness are produced by sequential extrusion of curable silicone films, and partially but not fully crosslinking a preceding silicone film prior to extruding a next subsequent film.
    Type: Grant
    Filed: January 23, 2015
    Date of Patent: December 31, 2019
    Assignee: WACKER CHEMIE AG
    Inventors: Andreas Koellnberger, Alfred Schwinghammer
  • Production of thin silicone films
    Patent number: 9950453
    Abstract: Thin silicon films of high thickness uniformity and thicknesses of from 0.1 ?m to 200 ?m are prepared by applying a crosslinkable silicone composition to a moving carrier by means of a slot die, removing solvent, if present, and subsequently crosslinking the silicone layer formed on the carrier.
