The invention relates to silicone urethane (meth)acrylates, particularly having at least three (meth)acrylate groups and not more urethane groups than (meth)acrylate groups, methods for preparing said silicone urethane (meth)acrylates, compositions comprising said silicone urethane (meth)acrylates, and their use in the production of release coatings, protective films and protective coatings as well as their use in the manufacturing of 3D printed objects by means of stereolithography. L'invention concerne des méthacrylates d'uréthane de silicone, en particulier possédant au moins trois groupes méthacrylate et pas plus de groupes uréthane que de groupes méthacrylate, des procédés de préparation desdits méthacrylates d'uréthane de silicone, des compositions comprenant lesdits méthacrylates d'uréthane de silicone, et leur utilisation dans la production de revêtements antiadhésifs, de films de protection et de revêtements de protection, ainsi que leur utilisation dans la fabrication d'objets imprimés en 3D par stéréolithographie.
