Beschreibung
Zusammenfassung:	A thermosetting composition comprising a crosslinkable component such as a vinyl ester and/or an unsaturated polyester, and an initiator component, such as cumene hydroperoxide or BPO or blends of cumene hydroperoxide and methyl ethyl ketone peroxide. The composition is suitable to be used in additive manufacturing to form objects such as molds or prototypes. La présente invention concerne une composition thermodurcissable comprenant un composant réticulable tel qu'un ester vinylique et/ou un polyester insaturé, et un composant initiateur, tel que l'hydroperoxyde de cumène ou le BPO ou des mélanges d'hydroperoxyde de cumène et de peroxyde de méthyléthylcétone. La composition est appropriée pour être utilisée dans la fabrication additive afin de former des objets tels que des moules ou des prototypes.
