Abstract: 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 ?-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.

Abstract: 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.

Abstract: 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.
