This application relates to polysiloxane compositions grafted with improved heat curable, moisture curable, or heat/moisture curable groups. In particular, the polysiloxane compositions have reactive groups on the terminal or pendent areas of the siloxane backbone, which once reacted provide improved heat and/or moisture curable polysiloxanes.

Polysiloxanes grafted with radically curable and/or moisture curable groups

The present invention relates to curable silicone compositions which include a fluorescent agent for detection purposes and which have a cure system which enables the silicone compositions to possess improved depth of cure. The silicone compositions are photocurable, and may also be moisture or heat curable.

Curable silicone compositions incorporating a fluorescent detection system

The present invention relates to photoradiation and/or moisture curing silicone compositions and methods for producing and using the same. In particular, the methods of the present invention permit controlled growth of a polymer, and allow for incorporation of pendant functional groups along the length of the polymer.

Reactive polyorganosiloxanes having controlled molecular weight and functionality

The present invention relates to a process for forming a cured-in-place gasket by liquid injection molding. More particularly, the present invention relates to a low pressure and room temperature process for forming a cured-in-place gasket by liquid injection molding.

Injection molding process, apparatus and material for forming cured-in-place gaskets

The present invention generally relates to a moisture curable composition in the form of a hot melt. The inventive compositions contain hydrolyzable silyl groups connected to a polymer which is capable of crosslinking when exposed to moisture.

Moisture curable silicone hot melt

The present invention provides curable hot melt compositions including reactive polymers, which are reinforced by organic polymers to impart higher tensile strength and elongation to the compositions upon cure. In particular, the present invention provides curable hot melt compositions including a silicone urea based polymer and a reinforcement polymer. In some embodiments, the compositions cure upon exposure to moisture and/or radiation. The compositions may be used, for example, as sealants or adhesives.

Moisture curable silicone urea hot melt reinforced by organic polymers

A room temperature vulcanizing silicone polymer composition including:  Enhanced elongation ability is possessed by these compositions.

Highly elongated single component, non-corrosive RTV silicone compositions

The invention provides fast moisture and photo/moisture curing silicone compositions and methods for the preparation thereof. More particularly, the compositions provided are prepared from silanol and silane cappers; the cappers have an &#x3b1;-carbon bonded to the silicon atom allowing for a favorable hypervalent silicon transition state when reacting the silane and silanol. This favorable transition state enables both a fast endcapping reaction and contributes to the fast moisture curing properties of the inventive compositions.

Fast moisture curing and UV-moisture dual curing compositions

The invention provides a reaction product derived from an epoxy-functional acrylic monomer and an alkylaminoalkylene polyalkoxysilane or from a reaction product derived from acrylic acid and an epoxidized polyalkoxysilane.

Polyurethane compositions containing both radiation and moisture curable groups

This invention relates to resin-reinforced silicone compositions curable upon exposure to radiation in the electromagnetic spectrum, which compositions when cured demonstrate improved elastomeric properties, such as tensile strength, modulus and elongation. The inventive resin-reinforced silicone compositions may alternatively be rendered curable by exposure to moisture. In addition, the inventive composition may be rendered curable by exposure to radiation in the electromagnetic spectrum, and exposure to moisture. The inventive silicone compositions are particularly well suited for use in electronic conformal coating and potting applications, as well as in automotive gasketing applications, pressure sensitive adhesive applications and the like.

Resin-reinforced UV, moisture and UV/moisture dual curable silicone compositions

The present invention relates to the preparation of a new class of materials, namely, an acrylate terminated or end-capped urethane/urea copolymer containing silicone soft segments capable of dual cure via unsaturated groups and dialkoxyl silanol groups. This new class of material is a reaction product of a partially methacrylated end-capped urethane polymer containing hard segment blocks and an amino alkylene dialkoxy end-capped siloxane block polymer, containing soft-segments. The aminoalkylene dialkoxysilane end-capped siloxane segment of this copolymer can include siloxane diol segments of various molecular weights (e.g., 1,000 to 20,000) end-capped with various alkylaminoalkylene trimethoxy silanes. This copolymer is therefore capable of dual cure via these functional groups.

Methacrylated polyurethane copolymers with silicone segments containing alkoxysilyl groups

The present invention relates to dual curing silicone compositions which are capable of cross-linking when subjected to ultraviolet (&ldquo;UV&rdquo;) or visible (&ldquo;VIS&rdquo;) 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.

Dual curing silicone compositions

The present invention provides anaerobic adhesive compositions, reaction products of which demonstrate controlled-strength at ambient temperature conditions and enhanced resistance to thermal degradation at elevated temperature conditions. The compositions are (meth)acrylate- and/or polyorganosiloxane-based and may include one or more of a variety of other components, such as certain coreactants, a maleimide component, a diluent component reactive at elevated temperature conditions, mono- or poly-hydroxyalkane components, and other components.

High temperature, controlled strength anaerobic compositions curable under ambient environmental conditions

The invention relates to a catalyst system for reacting a silanol group with an alkoxysilane containing a polymerizable ethylenically unsaturated group. The catalyst system includes an organo-lithium reagent and a hydroxylamine. The catalyst system, permits reaction of the silanol group with alkoxysilanes containing rapidly polymerizable ethylenically unsaturated groups, such as an acryloxyalkyl group, for instance an acryloxypropyl group.

Catalyst system, process, and silicone compositions

A curable composition, having utility for threadlocking engageable members of a threaded mechanical fastener, comprising: a reactive silicone (meth)acrylate emulsified in an aqueous medium, optionally further comprising a polymerizable non-silicone (meth)acrylate monomer or oligomer; and a microencapsulated peroxy initiator which is initiatingly effective for cure of the reactive silicone (meth)acrylate. The curable composition may be usefully employed for adhesively bonding engageable structural parts, by applying the aqueous emulsion of the reactive silicone (meth)acrylate, containing a microencapsulated peroxy initiator, to at least a portion of an engagement surface of a matable part which is matably engageable with a complimentary engagement structure, to yield an emulsion-coated engagement surface, drying the emulsion-coated engagement surface to form a dried coating thereon; and thereafter engaging the surface having the dried coating thereon, with the complimentary engagement structure, to release the microencapsulated peroxy initiator and bond the matable part and complimentary engagement structure.
