Polysiloxane composition for optical three-dimensional modeling, cured product and optical three-dimensional modeling product

摘要

PROBLEM TO BE SOLVED: To have an excellent balance of rubber elasticity, heat resistance and light resistance, which are the original excellent properties of a curable silicone-based composition, to have low viscosity and excellent storage stability, and to have a curing performance suitable for optical three-dimensional modeling. To provide a polysiloxane composition for optical three-dimensional modeling having the above. SOLUTION: A polysiloxane composition for optical three-dimensional modeling containing the following components (A) to (D). Further, the following component (E) may be contained. Component (A): Polysiloxane compound containing two or more alkenyl groups in one molecule Component (B): Siloxane compound containing two or more hydrosilyl groups in one molecule Component (C): Photoactive platinum-based catalyst Component (D): Reaction inhibitor having a boiling point of 150 ° C. or lower under normal pressure Component (E): Silica [Selection diagram] FIG.
