fluoropolyether
compound having at least two alkenyl groups and a perfluoropolyether structure,
(B) an organosilicon compound having at least two SiH groups, (C) a perfluoroparaffin
or derivative in powder form, at least 80% by weight of which volatilizes off when
held in a drier at 200 C. for 4 hours, and which has a melting point of at
least 50 C., and (D) a hydrosilylation catalyst cures into a product that
exhibits solvent resistance, chemical resistance, weather resistance, water repellency,
oil repellency and heat resistance, and is improved in mold release and compression set.
