Cross-linkable coating composition.

摘要

A cross-linkable coating composition comprising a fluorine-containing elastomeric copolymer which comprises (a) 50 to 95 % by mole of repeating units derived from a fluoroolefin of the formula: CF2=CXY (I) wherein X and Y are the same or different and a fluorine atom or a chlorine atom, (b) 50 to 5 % by mole of repeating units derived from a perfluorovinyl ether of the formula: Rf-[OCFZCF2(CF2)m]n-OCF=CF2 (II) wherein Rf is a C1-C6 perfluoroalkyl group, Z is a fluorine atom or a trifluoromethyl group, n is an integer of 0 to 5 and m is 0 or 1 provided that when m is 1 (one), X is not a trifluoromethyl group and a cross-linking agent for the copolymer, the copolymer and the cross liking agent being dissolved or dispersed in a fluorosolvent is provided.
