Liquid radiation-curable composition especially for producing cured articles by stereolithography having high heat deflection temperatures

The present invention provides a liquid resin composition comprising: (a) at least one cationically curable compound comprising an alicyclic polyepoxide having at least two epoxy groups per molecule with a monomer purity of over 94%; (b) at least one photoinitiator for the cationically cured compond...

Beschreibung
Zusammenfassung:	The present invention provides a liquid resin composition comprising: (a) at least one cationically curable compound comprising an alicyclic polyepoxide having at least two epoxy groups per molecule with a monomer purity of over 94%; (b) at least one photoinitiator for the cationically cured componds; (c) a free-radically-curable component and (d) a free radical photoinitiator. The use of the high purity alicyclic polyepoxide provides unusually good thermal performance
