  • Method for applying at least one silicone layer by laser transfer printing
    Patent number: 11903320
    Abstract: At least one silicone layer is applied to a substrate by a method employing laser transfer printing. The method is suitable for producing sensors, actuators and other EAP layer systems. The silicone layer in these systems may serve as an electrically conducting electrode layer or as a dielectric layer. The method may be configured to be continuous and may be combined with various other coating technologies.

  • STABILIZATION OF NOBLE METAL CATALYSTS
    Publication number: 20200172677
    Abstract: Shelf life of noble metal catalyzed addition crosslinkable organosilicon compositions is remarkably increased by treatment of a noble metal catalyst having an oxidation state greater than 0 with a bidentate chelate compound. The latter may remain in the catalyst mixture or be removed, and the treatment may be performed in situ or ex situ with respect to the remainder of the crosslinkable composition components.
