ABSTRACT:
A curable silicone composition for a vibration-isolating laminate comprising (A) 100 parts by weight of an organopolysiloxane having at least two alkenyl groups per molecule and a viscosity of 10-100,000 mPa.s at 25.degree. C.; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule and a viscosity of 1-100,000 mPa.s at 25.degree. C. in an amount such that this component contains 0.2-5 mol of silicon atom-bonded hydrogen atoms per mole of alkenyl groups in component (A); (C) 1-300 parts by weight of an inorganic filler; and (D) a hydrosilylation catalyst in an amount sufficient to cure the composition, designed for forming a cured silicone product for a vibration-isolating laminate by laminating a metal layer and a cured silicone layer having a loss factor of 0.4 or greater and a storage modulus of 1.0.times.10.sup.5 dyne/cm.sup.2 or greater at 25.degree. C. and a shear frequency of 0.2 Hz.
