WATER-REPELLENT, OIL-REPELLENT COMPOSITE FILM FORMATION SOLUTION, METHOD FOR MANUFACTURING A WATER-REPELLENT, OIL-REPELLENT COMPOSITE FILM USING THE SAME, AND WATER-REPELLENT, OIL-REPELLENT COMPOSITE FILM MANUFACTURED BY USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide, on an occasion for forming, on windows of automobiles or buildings or top plates of electromagnetic cookers, a water-repellent, oil-repellent antifouling film excellent in terms of abrasion resistance, weather resistance, water droplet separability, and antifouling capacity, a water-repellent, oil-repellent composite film formation solution unaccompanied by the generation of hydrochloric acid (or capable of greatly abating the generation thereof).SOLUTION: The provided water-repellent, oil-repellent composite film formation solution includes not only (1) CF3(CF2)n(CH2)2Si(OA)3, [CF3(CF2)n(CH2)2]2Si(OA)2, or [CF3(CF2)n(CH2)2]3SiOA (n is an integer of 1 to 22; A is an alkyl group), (2) Si(OCH3)4, Si(OC2H5)4, (CH3O)3Si(OSi(OCH3)2)mOCH3 (m is an integer), SiH(OC2H5)3, SiH2(OC2H5)2, or (C2H5O)3Si(OSi(OC2H5)2)mOC2H5 (m is an integer), and (3) a non-aqueous organic solvent but also (4) a silanol condensation catalyst or (5) an acid catalyst.
