PHOTOPOLYMERIZABLE COMPOSITION BASED ON AN EPOXYVINYLESTER RESIN AND A URETHANE ACRYLATE RESIN AND USE THEREOF FOR MAKING DENTAL PROSTHESIS PREFORMS AND/OR MODELS

摘要

The invention concerns a photopolymerizable composition comprising: at least one epoxyvinylester resin, at least one urethane acrylate resin, at least one organic silicon-free particulate filler having an average particle size less than 10 νm and a specific surface more than 10 m2/g, at least one photoinitiator. Said composition is in particular useful for making dental prosthesis preforms and models.
