    摘要： The present invention provides silicone compositions, cured elastomers thereof demtonstrate improved resistance to oil. The compositions include a reactive silicone component, wherein the silicone component cures by way of an addition cure mechanism or a condensation cure mechanism; and a basic filler component to confer oil resistance to the cured elastomer. Where the reactive silicone component cures by way of an addition cure mechanism, an addition cure catalyst is also included. To that end, in one embodiment of the invention, the composition includes a vinyl-terminated silicone fluid, a hydrogen-functionalized silicone fluid; a basic filler to confer oil resistance to the cured elastomer and an addition cure catalyst. In another embodiment of the invention, the composition includes a hydroxy-terminated diorganopolysiloxane, a precipitated calcium carbonate, at least about 5% by weight of a composition comprising magnesium oxide particles having a mean particle size of about 0.5 &mgr;M to about 1.5 &mgr;M and a mean surface area of about 50 M2/g to about 175 M2/g and a crosslinker.

    摘要： Vibration dampening hydrosilation cured silicone formulations which cure at room temperature and, after a subsequent heat cure cycle, provide good primerless adhesion to aluminum and titanium substrates and improved adhesion to polymeric composite materials such as polyimide/glass fiber composite materials. The composition includes (a) a polyorganosiloxane having plural alkenyl groups thereon; (b) a polyorganosiloxane having plural silicon hydride groups thereon; (c) a hydrosilation catalyst, and (d) a combination of adhesion promoter compounds including at least one silane adhesion promoter compound; triallyl isocyanurate; and diallyl maleate. Still further improvements to polyimide substrates are provided when a primer is employed or the substrate is treated by a very brief exposure to a flame or to UV irradiation.
