Patent ID: 8236195

Claim:
A method for curing a fluorine-containing curable composition containing (A) a fluorine-containing amino compound having primary or secondary amino groups at both ends, said compound being represented by the formula (1): Y-Q-Rf—(X—Rf) n -Q-Y (1) wherein Rf is a divalent perfluorooxyalkylene group, each Q is independently a divalent organic group having 1 to 20 carbon atoms and, optionally, containing an oxygen atom and/or a nitrogen atom, X is a divalent organic group having 1 to 20 carbon atoms and, optionally, containing an oxygen atom and/or a nitrogen atom, Y is an organic group having a primary or secondary amino group and 1 to 20 carbon atoms and, optionally, containing an oxygen atom, and n is an integer of from 1 to 20, and (B) an epoxy compound having at least two epoxy groups in a molecule, in an amount such that the amount of the epoxy groups is 0.8 to 2 moles per mole of the amino groups of component (A), and wherein the method comprises the steps of adding (C) at least one alcohol containing fluorine atoms to the aforesaid fluorine-containing curable composition in an amount such that the amount of the alcoholic hydroxyl group is 0.01 to 0.2 mole per mole of the amino groups of component (A), wherein the alcohol is represented by the following formula (2): Rf′(CH 2 OH) m (2) wherein m is an integer of 1 or 2, Rf′ is a monovalent or divalent group containing 2 to 300 fluorine atoms, and at least one fluorine atom or at least one trifluoromethyl group is bonded to a carbon atom to which the methylol group is bonded, and allowing the composition to cure, wherein (C) the alcohol containing fluorine atoms, works as a catalyst.
