FLUORINE-CONTAINING ETHER COMPOSITION METHOD FOR PRODUCING SAME COATING FLUID AND METHOD FOR MANUFACTURING SUBSTRATE HAVING SURFACE-TREATED LAYER

摘要

The present invention provides a fluoroether composition capable of imparting good water repellency and oil repellency to the surface of a base material and having excellent friction resistance and not being deteriorated in performance even by repeated rubbing. Ratio of including the AOR ^F -B, fluorine ether compound B is also more different two kinds represented by, and the proportion of the group, a group (5-1) of the total number of B 90 ~ 95% by mole, based 5-2 Is from 5 to 10 mol%. A is an alkyl group or a perfluoroalkyl carbon number of 1 ~ 6 B. R ^F is _{- (CF 2 CF 2 O)} b (CF (CF 3) CF 2 O) c (CF 2 O) d (CF 2 CF 2 CF 2 O) _e -, and the order of repeating units is not limited. b, c, d and e are each independently an integer of 0 or more, and b + c + d + e is 5 to 150; (5-1): - (CF ₂ ) _a CFXCH ₂ OCH ₂ CH ₂ CH ₂ SiL _m R _n (5-2): - (CF ₂ ) _a CFXCH ₂ OCH ₂ CH (SiL _m R _n ) CH ₃ (5-3): - (CF ₂ ) _a CFXCH ₂ OCH ₂ CH = CH ₂ (5-4): - (CF ₂ ) _a CFXCH ₂ OCH = CHCH ₃ [a is 0 or 1, X is F or CF _3, L is a hydrolyzable group, R is a hydrogen atom or a monovalent hydrocarbon group, m is an integer of 1 ~ 3, n is an integer of 0 ~ 2, m + n = 3]
