Abstract
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═C; X is —C(O)NH— or —C(O)—; Ris —O—, —O[CH(R)]O—, —(CH)O—, —OC(O)—(CH)O— or —(CH)OC(O)—(CH)O—, where Ris —H, —OH, —CHOH or —O—X—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.
