Title:
PHOTOCURABLE POLYSILOXANE COMPOSITION FOR 3D PRINTING, AND DENTAL MOLD COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/004601
Kind Code:
A1
Abstract:
The present invention relates to a photocurable polysiloxane composition for 3D printing, and a dental mold comprising the same. A photocurable composition for 3D printing comprising a novel polysiloxane compound according to one aspect is suitable for use as a dental material because a cured product thereof has excellent hardness, strength, elongation, heat resistant coloring properties, light resistant coloring properties, flexural properties, and biocompatibility. In addition, the photocurable composition has an advantageous effect on a 3D printing process because the photocurable composition is in a liquid phase, which is easy in terms of control of molecular weight and viscosity.
