ANTIMONY-FREE PHOTOCURABLE RESIN COMPOSITION AND THREE DIMENSIONAL ARTICLE

摘要

The present invention provides a low viscosity photocurable composition including (i) a cationically curable component (ii) a free radically active component (iii) an antimony-free cat ionic photoinitiator and (v) a free radical photoinitiator. The photocurable composition can be cured using rapid prototyping techniques to form three-dimensional articles which can be used in various aerospace and investment casting applications.
