  • SILICONE URETHANE (METH)ACRYLATES AND THEIR USE IN 3D PRINTING RESINS AND COATING COMPOSITIONS
    Publication number: 20240101752
    Abstract: Silicone urethane (meth)acrylates can have at least three (meth)acrylate groups and not more urethane groups than (meth)acrylate groups. A method for preparing the silicone urethane (meth)acrylates involves reacting at least one hydroxy functional silicone (meth)acrylate with at least one isocyanate functional urethane (meth)acrylate. Compositions can contain the silicone urethane (meth)acrylates, and are useful for the production of release coatings, protective films, and protective coatings; and for the manufacturing of 3D printed objects by stereolithography.
