Composition of comprising nano metal oxide/hydroxide particles and a polyorganosiloxane having increased refractive index, processes to cure these compositions for making transparent coats, shaped articles by an extrusion or molding process having a refractive index above the refractive index of the polyorganosiloxane. Use of the cured polyorganosiloxane compositions as optical devices, coats, lenses or light guides.

Modified filler particles and silicone compositions comprising the same

A heterogeneous catalyst comprising a metal-containing polymer matrix covalently bonded to a support material and a method of making and using such catalysts. The metal-containing polymer matrix comprises metal nano-particles encapsulated in a polymer matrix, e.g., a siloxane. In one aspect, the metal-containing polymer matrix can be bonded to the support material via a hydrophobic group attached to the support material. The catalyst can be recovered after being used in a metal catalyzed reaction and exhibit excellent catalytic activity upon reuse in subsequent reactions.

High activity catalyst for hydrosilylation reactions and methods of making the same

A curable composition comprises (a) a mercapto-functional siloxane; (b) a siloxane comprising unsaturated functional groups; (c) a photoinitiator; and (d) an antioxidant compound. In one embodiment, the antioxidant is chosen from a hindered phenolic compound. The curable compositions can be utilized to form a cured article, which may be useful in a variety of applications including, but not limited to, optical applications. The cured articles from the cured compositions may exhibit good physical properties including, for example, high refractive index. The articles may also exhibit good thermal stability.

Thermally stable, high refractive index curable silicone compositions

The invention relates to curable, storage-stable silicon-containing compositions reinforced with functionalized silica useful as one and two-part sealant and adhesive systems. The cured compositions provide silicon-containing rubber having excellent translucency, physical properties and primerless adhesion.

Curable silicon-containing compositions possessing high translucency

A method for producing a functionalized silica, compositions and methods for forming curable silicone rubber compositions by using the functionalized silica are also disclosed. Compositions and methods for forming cured silicone resin compositions and products having high transparency, high tensile strength, desirable percent elongation, or a combination of the foregoing properties are also disclosed.
