摘要:
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 R 1 is hydrogen atom or methyl group; R 2 is a hydrocarbon group having ethylenic C=C; X is -C(O)NH- or -C(O)-; R 3 is -O-, -O[CH(R 4 )] m O-, -(CH 2 ) m O-, -OC(O)-(CH 2 ) n O- or -(CH 2 ) m OC(O)-(CH 2 ) n O-, where R 4 is -H, -OH, -CH 2 OH or -O-X-R 2 , 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.
