Patent number: 11332582Abstract: Crosslinkable or crosslinked silicone compositions that can be used, in particular, to form a non-stick and water-repellent coating or film for flexible substrates and in the form of natural or synthetic polymer films are provided. These compositions comprise crosslinking organopolysiloxanes bearing SiH units and unsaturated organopolysiloxanes, preferably vinyl organopolysiloxanes, capable of reacting with the crosslinker by addition reaction, in the presence of platinum in order to form the non-stick crosslinked coating on the flexible substrate, and at least one crosslinking and attachment-promoting additive X. These compositions are advantageously free of solvent and can be crosslinked instantaneously into a non-stick and/or water-repellent coating for a flexible substrate.Type: GrantFiled: September 22, 2016Date of Patent: May 17, 2022Assignee: Elkem Silicones France SASInventors: Michel Feder, John White, Sébastien Marrot
