Approaches are described for coating various flexible media, such as sheets of paper, synthetic polymer (polyolefin, polyester, etc.) sheets or fabric sheets, with a silicone on high-speed rolls. For example, an efficient method is described for minimizing and/or reducing mist formation when coating flexible supports with a liquid silicone composition precursor of crosslinked coatings. The coating process can be performed using a coating device that includes a roll operating at a high speed.
