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. Una composición termoestable que comprende un componente entrecruzable, como un éster vinílico y/o un poliéster insaturado, y un componente iniciador, como hidroperóxido de cumeno o BPO, o mezclas de hidroperóxido de cumeno y peróxido de metiletilcetona. La composición es apropiada para utilizarse en la fabricación aditiva para formar objetos como moldes o prototipos.
