Fluorine-containing organopolysiloxane composition.

摘要

A room temperature curable fluorine-containing organopolysiloxane composition comprising: (A) a fluorine-containing organosilicon compound having the general formula (1): R<2>-NHCO-[Rf-CONH-R<1>-Q-R<1>-NHCO]a-Rf-CONH-R<2> (1) wherein a is an integer of 0 or more, Rf is a divalent perfluoroalkylene group or a divalent perfluoropolyether group, R<1> is a divalent hydrocarbon group, R<2> is a monovalent aliphatic unsaturated group-containing hydrocarbon group, and Q is a divalent siloxane group (B) a hydrogenorganopolysiloxane containing at least two Si-H groups in its molecule, and (C) a platinum family metal catalyst. The cured product of this composition exhibits good solvent resistance against non-polar solvents as well as polar solvents, in addition to good chemical resistance, heat resistance, release properties and water repellency.
