Color-changeable organopolysiloxane composition and structural material adhered by the composition

摘要

This is to provide an organopolysiloxane composition curable at room temperature wherein a curing degree can be visually recognized when the composition is cured, and the color-changeable organopolysiloxane composition comprises
(A) 100 parts by mass of an organopolysiloxane composition curable at room temperature,
(B) 0.01 to 10 parts by mass of cobalt chloride, and
(C) 0.001 to 10 parts by mass of a silane coupling agent represented by the following formula (1),
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(R 1 O) 3-n R n SiQ 1 NHQ 2 NH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R and R 1 may be the same or different from each other, and each represent an unsubstituted or substituted monovalent hydrocarbon group having 1 to 10 carbon atoms; Q 1 and Q 2 may be the same or different from each other and each represent an unsubstituted or substituted divalent hydrocarbon group having 1 to 10 carbon atoms; and "n" represents an integer of 0 to 2.
