摘要： The field of the invention is that of the preparation of release and water-repellent coatings on a support, preferably a flexible support, such as a support made of paper or of synthetic polymer film, preferably of the polyolefin, polypropylene, polyethylene or polyester type. The release coatings taken into consideration are more especially those based on silicone elastomer crosslinked after coating on these supports.

摘要： The present invention relates to a coating method wherein a silicone composition crosslinkable by polyaddition reactions is used to form a silicone elastomer on an open-work and/or elastic textile medium. The crosslinking of the silicone composition is obtained by irradiating with UV radiation, the source of which is a UV-LED lamp.

摘要： The present invention concerns type II photoinitiators for the free-radical crosslinking of silicone compositions, in particular acrylic silicone compositions. The present invention concerns a silicone composition C1 that can be crosslinked by exposure to radiation with a wavelength of between 300 and 450 nm, comprising:—at least one organopolysiloxane A comprising at least one methacrylate group bonded to a silicon atom, at least one organohydrogenopolysiloxane H comprising at least two, and preferably at least three hydrogen atoms each bonded to different silicon atoms, and—at least one free-radical photoinitiator P. The present invention also concerns the provision of a silicone composition that can be polymerized or crosslinked by free-radical process comprising a type II photoinitiator system suitable for crosslinking silicone compositions, in particular by exposure to radiation, and absorbing light radiation with a wavelength greater than 300 nm.

摘要： 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.
