Abstract:
A curable silicone elastomer composition comprising:100 parts by weight of a vinyl-containing polydimethylsiloxane polymer; from about 0.002 to about 6.67 parts by weight platinun; from about 0.5 part to about 1.5 parts by weight of allyltrimethoxysilane; from about 5 to about 100 parts by weight of filler selected from the group consisting of precipitated silica, fumed silica and mixtures thereof; from about 0.1 to about 25 parts by weight of an Si-H containing polysiloxane crosslinker resin; a linear hydride polysiloxane coupler having a viscosity from about 1 to about 500 centipoise at 25Â° C.; and wherein the elastomer cures at a temperature from about 20Â° C. to about 100Â° C., to form a high strength adhesive bond having a Shore A durometer of at least about 35 durometer, tensile strength of at least about 750 psi (5.2 Mpa), elongation of at least 400%, and Tear B of at least about 100 Pi (17.6 KN/M).
