Abstract
Abstract A curable composition comprising (A) a fluorinated organic silicon compound of the formula: Z-R<1>-Rf-R<1>-Z wherein Rf is a divalent fluorinated polyether group, R<1> is a divalent hydrocarbon group, and Z is a silyl or siloxane group terminated with OH, (B) an organic silicon compound as a crosslinking agent, and (C) a condensation accelerator is curable to depth at room temperature even in the absence of moisture.
