Title:
UV-CURABLE SILICONE COMPOSITION FOR STEREOLITHOGRAPHY, CURED PRODUCT THEREOF, AND METHOD FOR PRODUCING CURED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2022/224793
Kind Code:
A1
Abstract:
Provided is a UV-curable silicone composition containing: (A) an organopolysiloxane having, in one molecule, two groups represented by formula (1) (R1 is a monovalent hydrocarbon group, R2 is an oxygen atom or an alkylene group, R3 is an acryloyloxyalkyl group, etc., p represents a number satisfying 0≤p≤10, and a represents a number satisfying 1≤a≤3.); (B) an organopolysiloxane resin which comprises (a) a unit represented by formula (2) (R1 to R3, a and p are the same as above), (b) a R4
3SiO1/2 unit (R4 represents a monovalent hydrocarbon group), and (c) a SiO4/2 unit, and in which a molar ratio of the sum of the unit (a) and the unit (b) and the unit (c) is 0.6 to 1.2:1; (C) a photopolymerization initiator; and (D) an organic peroxide, wherein the UV-curable silicone composition has a viscosity applicable to a stereolithography such as a laser process, can be shaped even with a small amount of UV irradiation, and forms a cured product exhibiting excellent rubber physical properties.
