  • Publication number: 20100139843
    Abstract: The present invention provides one-component silicone compositions, particularly useful as sealants, having low modulus and high elongation, as well as good resistance to high temperatures and humidity, and methods for preparing these sealants. In particular, the present invention provides compositions including a chain-extended curable polyorganosiloxane, a high molecular weight silicone gum and a cure system. The compositions may be used, for example, in sealing the stitching of automotive airbags.

  • Patent number: 6864340
    Abstract: The present invention provides novel “hybrid” silyl-terminated polymers that contain at least two different reactive end-capping groups. The “hybrid” silyl-terminated polymers of the present invention are produced by a novel single multi-step end-capping reaction of at least one silanol-terminated polymer with at least two silanes in the presence of a catalyst.

  • Patent number: 6645339
    Abstract: Silicone compositions are disclosed which exhibit excellent adherence to magnesium-based substrates such as magnesium alloys and which exhibit excellent resistance to organic solvents. These compositions include at least one polymerizable silicone component, at least one amino-containing silane adhesion promoter which enhances adhesion of the composition to magnesium-based substrates, and at least one viscosity modifier, which enhances the resistance of the compositions to organic solvents. Methods of making these compositions, articles of manufacture including these compositions, and a method for providing enhanced adhesion to magnesium-based substrates using these compositions are also disclosed.

  • Patent number: 6451870
    Abstract: The present invention relates to dual curing silicone compositions which are capable of cross-linking when subjected to ultraviolet (“UV”) or visible (“VIS”) light and/or by a moisture condensation method. When cured, these compositions have excellent adhesion to a variety of substrates. These are particularly useful in potting and coating applications.

  • Patent number: 6444740
    Abstract: 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.

  • Patent number: 5434214
    Abstract: 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.
