Abstract:
A curable silicone composition for a vibration-isolating laminate comprising (A) 100 parts by weight of a mixture of (i) an organopolysiloxane described by mean unit formula (R.sub.3 SiO.sub.1/2).sub.x (R.sub.2 SiO.sub.2/2).sub.y (RSiO.sub.3/2).sub.z, where R is a substituted or unsubstituted monovalent hydrocarbon group and at least two R groups per molecule are alkenyl groups, x is a number from 0.01 to 10, y is a number from 80 to 99.7, and z is a number from 1 to 5 and (ii) a linear 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 1-10,000 mPa.s at 25.degree. C. in an amount such that said 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, where the curable silicone composition when cured has 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.
