摘要： 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.
