  • Antimony-free photocurable resin composition and three dimensional article
    Patent number: 8334025
    Abstract: 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 cationic photoinitiator (v) a free radical photoinitiator, and (vi) a toughening agent. 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.

  • PHOTOCURABLE COMPOSITIONS FOR PREPARING ABS-LIKE ARTICLES
    Publication number: 20100119835
    Abstract: The present invention relates to a photocurable composition comprising: (a) 30-80% by weight of an epoxy-containing component (b) 5 to 65% by weight of a compound containing an oxetane ring in its molecule; (c) 1-25% by weight of a polyol having a molecular weight Mw of 2.000 or higher, (d) an antimony-free cationic photoinitiator. wherein the percent by weight is based on the total weight of the photocurable composition. The curable resin composition can be used for photocurable coatings per se and in specific for stereolithography and other such three dimensional printing applications where a 3D object is formed.
