Document Type and Number:
Japanese Patent JP2022141921
Kind Code:
A
Abstract:
To provide a cured product of a silanol composition having excellent crack resistance during light irradiation and a curing method therefor.SOLUTION: The present invention discloses a cured product of a silanol composition comprising a cyclic silanol containing a silanol group and having a cyclic structure formed by a siloxane bond, and a dehydration condensate thereof. In an IR spectrum, the ratio of a peak area derived from SiO-H stretching observed at 2600 to 3800 cm-1 to a peak area derived from Si-O-Si stretching observed at 960 to 1220 cm-1 (SiO-H stretching/Si-O-Si stretching area ratio) is 0.01 or more.SELECTED DRAWING: None
