摘要： The present invention relates to a photo-curable silicone composition comprising a release control additive which is an organopolysiloxane resin comprising Si—OH groups. In particular, the invention relates to a silicone composition comprising at least one organopolysiloxane A including at least one (meth)acrylate group, at least 25% by weight of an organopolysiloxane resin B comprising Si—OH groups, and at least one radical photoinitiator C. The compositions of the invention can be used to form release coatings.

摘要： A process is provided for preparing composite articles composed of a rigid glass, metal or thermoplastic resin substrate and of a silicone elastomer with good mechanical properties and good adhesion between the substrate and the silicone elastomer E such that there is a solid bond between the two parts. The composite articles are used in very diverse fields such as electrical and electronic equipment, motor vehicle and medical equipment, and they may be found, for example, in household appliances, consumer goods, medical equipment and sports and leisure articles.

摘要： 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.
