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 a method for the additive manufacturing of a silicone elastomer article using a 3D printer. The invention also relates to a crosslinkable silicone composition for the additive manufacturing of a silicone elastomer article.

The invention relates to the general field of coating various flexible supports, such as sheets of paper or synthetic polymer (polyolefin, polyester, etc) sheets or fabric sheets, with a silicone on high-speed rolls. The invention relates to an efficient method for preventing mist formation when coating flexible supports with a liquid silicone composition precursor of cross-linked coatings, said coating process being performed using a coating device that includes a roll operating at a high speed.
