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.

Method for coating a textile medium

The invention relates to an additive manufacturing process for producing a silicone elastomer item. In particular, the invention relates to an additive manufacturing method for producing a silicone elastomer item from a photocrosslinkable silicone composition. The invention also relates to a photocrosslinkable silicone composition.

Additive manufacturing method for producing a silicone elastomer item

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: &#x2014;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&#x2014;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.
