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.
