Provided is a curable silicone composition and applications thereof. The curable silicone composition has hot-melt properties, excellent workability, and curing characteristics such as overmolding, and a cured product obtained therefrom does not become hard or brittle, even if left at a temperature of 150° C. or higher for a long time. The curable silicone composition comprises: an organopolysiloxane resin component which is non-hot-meltable, comprises a siloxane unit represented by SiOmaking up at least 20 mol % or more of the total siloxane units, and has a mass loss of 2.0 mass % or less when exposed to 200° C. for 1 hour; a liquid straight-chain or branched chain organopolysiloxane; and a curing agent.

There is provided a curable fluorine-containing polymer composition which is quickly cured at relatively low temperatures by hydrosilylation reaction and provides a coating film which has high hardness, excellent solvent resistance and flexibility. The curable fluorine-containing polymer composition comprises a fluorine-containing polymer comprising a fluorinated ethylenic monomer unit and a non-fluorinated ethylenic monomer unit, in which a part or the whole of the non-fluorinated ethylenic monomer units is a unit represented by the formula: wherein Ris hydrogen or methyl; Ris a hydrocarbon group having ethylenic C&#x2550;C; X is &#x2014;C(O)NH&#x2014; or &#x2014;C(O)&#x2014;; Ris &#x2014;O&#x2014;, &#x2014;O[CH(R)]O&#x2014;, &#x2014;(CH)O&#x2014;, &#x2014;OC(O)&#x2014;(CH)O&#x2014; or &#x2014;(CH)OC(O)&#x2014;(CH)O&#x2014;, where Ris &#x2014;H, &#x2014;OH, &#x2014;CHOH or &#x2014;O&#x2014;X&#x2014;R, a siloxane compound having hydrogen atom bonded to silicon atom, and a catalyst for hydrosilylation reaction.

Curable fluorine-containing polymer composition

There is provided a curable fluorine-containing polymer composition which is rapidly cured at relatively low temperature by hydrosilylation reaction to form a coating film having not only high hardness and flexibility but also water- and oil-repellency, thereby giving stain-proofing effect for a long period of time, especially maintaining property of removing and wiping-off stain. The curable fluorine-containing polymer composition comprises a fluorine-containing polymer comprising a fluorinated ethylenic monomer unit and an un-fluorinated ethylenic monomer unit, in which a part or the whole of the un-fluorinated ethylenic monomer units are units represented by the formula: where Ris hydrogen atom or methyl group; Ris a hydrocarbon group having ethylenic C&#x2550;C; X is &#x2014;C(O)NH&#x2014; or &#x2014;C(O)&#x2014;; Ris &#x2014;O&#x2014;, &#x2014;O[CH(R)]O&#x2014;, &#x2014;(CH)O&#x2014;, &#x2014;OC(O)&#x2014;(CH)O&#x2014; or &#x2014;(CH)OC(O)&#x2014;(CH)O&#x2014;, where Ris &#x2014;H, &#x2014;OH, &#x2014;CHOH or &#x2014;O&#x2014;X&#x2014;R, a siloxane compound having hydrogen atom bonded to silicon atom, a catalyst for hydrosilylation reaction, and a siloxane compound having no hydrogen atom bonded to silicon atom.
