Title:
ULTRAVIOLET CURABLE SILICONE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/189929
Kind Code:
A1
Abstract:
The present invention provides an ultraviolet curable silicone composition which has excellent curability in a portion that is not irradiated with light and in the thickness direction. The present invention provides an ultraviolet curable silicone composition which contains: (A) a polyorganosiloxane that has at least two alkenyl groups in each molecule and an average alkenyl group content of 0.08 mmol/g or more; (B) a polyorganohydrogen siloxane that has at least three hydrogen atoms, which are bonded to silicon atoms, in each molecule; and (C) a platinum catalyst that is activated by ultraviolet light. With respect to a cured product that is obtained by irradiating the composition with ultraviolet light having a wavelength of 365 nm for 45 seconds at an illuminance of 100 mW/cm2 with a diameter of 7.0 mm in a yellow room and subsequently storing the resulting composition at 23°C for 16 hours, the curing diameter at a depth of 1.8 mm is 10.8 mm or more.
