Document Type and Number:
WIPO Patent Application WO/2020/129744
Kind Code:
A1
Abstract:
An addition-curable silicone rubber composition which contains: 100 parts by mass of (A) an organopolysiloxane that has at least two alkenyl groups, each of which is bonded to a silicon atom, in each molecule, and wherein an alkenyl group is bonded to a silicon atom at one end or both ends of the molecular chain; 1-80 parts by mass of (B) γ-cyclodextrin; (C) an organohydrogen polysiloxane that has at least two hydrogen atoms, each of which is bonded to a silicon atom, in each molecule in such an amount that the molar ratio of the hydrogen atoms bonded to silicon atoms (Si-H groups) to the total amount of the alkenyl groups bonded to silicon atoms in the entire composition, namely (Si-H groups)/(Si-alkenyl groups) is from 0.5 to 5.0; and a catalytic amount of (D) an addition reaction catalyst.
