Abstract
A liquid curable composition prepared from a polydiorganosiloxane having ethylenically unsaturation, a polyhydrogenorganosiloxane, a catalyst for the addition of silicon-bonded hydrogen to ethylenically unsaturation, a particulate filler wherein the composition cured to an elastomeric state has a loss modulus, E", of at least 100 MPa at -120.degree. C., a loss tangent of at least 0.15 at -120.degree. C., and a tear strength of less than 10 kN/m at 23.degree. C., makes an interlayer for a laminate of glass or other brittle which fails safely when receiving a breaking impact.
